The New York Times published <a href="http://www.nytimes.com/2011/01/21/us/21tttransmission.html?ref=science">a story</a> this week about Texas where the Public Utility Commission has struggled to site 2,300 miles of new transmission lines. Much of the battle revolves around citizens unhappy with the prospect of lines degrading the quality of public and private property. Utilities are also constrained and looking to avoid costs associated with circuitous routing and permitting.</p><p class="MsoNormal"><br /></p> <p class="MsoNormal"> </p> <p class="MsoNormal">Controversies over electricity lines always leave me envious of the Germans. In Germany, a country that stands near the top of world rankings for total wind capacity, distribution lines are mostly underground – a considerable factor in mitigating localized power outages caused by downed trees. Destruction of infrastructure during WWII explains why Germany has a more modern and reliable electricity system compared to the US. Germany is also exploring underground transmission options through <a href="http://www.germanenergyblog.de/?p=2118">a pilot project</a> near Bremen. Historically avoided due to premiums on installation and maintenance, underground transmission lines may be a solution to overcoming stateside NIMBY battles.</p><p class="MsoNormal"><br /></p> <p class="MsoNormal"> </p> <p class="MsoNormal">What exactly are the barriers to placing transmission lines underground? An operational barrier, emphasized by <a href="http://www.atcllc.com/IT5.shtml#operational">the American Transmission Company</a>, is the fact that electricity transmission creates heat, which must be dissipated for safe and reliable delivery of power. While air is a much more effective medium for heat transfer relative to soil, releasing heat into the atmosphere is a waste of a valuable resource. If heat is released into the soil, however, the challenge of heat dissipation may be an opportunity for efficient heat capture. Capturing electricity transmission waste heat is a concept I’ve not heard about. Geothermal heating and cooling, a process that uses convection and heat pumps to capture ground warmth, is the obvious comparison.</p><p class="MsoNormal"><br /></p> <p class="MsoNormal"> </p> <p class="MsoNormal">There seem to be opportunities for coupling underground transmission development with heat capture, or combined transmission and heating. Namely, a chief inefficiency in the electrical grid, unused electrons, can be transformed into a revenue generating tool as heat is captured and sold to customers. This benefit alone may be enough to overcome the cost barriers associated with placing transmission lines underground. On the other hand, it seems like a bad idea putting fluids in close proximity to an electrical current. An additional concern is infrastructure requirements (I.e., electrical and fluid piping) under the principle of placing people close to heat sources to minimize heat loss, but away from electrical currents to minimize health risks.<br /></p><p class="MsoNormal"><br /></p> <p class="MsoNormal"><span style=""> </span></p> <p class="MsoNormal">I believe that is as far as my hair-brained idea should go without consulting experts. What are your thoughts?

The Nuclear Energy Institute and many others <a href="http://www.nei.org/newsandevents/newsreleases/nei-files-amicus-brief-supporting-challenges-to-does-yucca-mountain-license-withdrawal/">support</a> the NRC's decision. But what people aren't talking about is how we got into this predicament in the first place. President Obama could use this situation to correct decades of poorly communicated policy on nuclear waste storage by keeping Yucca Mountain on the table but using a transparent decision analysis process with public participation that takes into account the efforts already expended on preparing Yucca Mountain for storage. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">In one of my classes here in Portugal, we had decision analysis expert Larry Philips give a guest lecture on the multi-attribute decision making process that Great Britain is using to determine how to handle their nuclear waste. (Multi-attribute decision making refers to the process of determining objectives, developing criteria from those objectives on which to score alternatives, weighting the importance of each criterion, and the determining the best alternative by ranking them by score.) After they finish the first process and decide on a method, they will enter another round of thoughtful deliberation on where to locate whichever waste storage method they choose. Intrigued, I asked him what he thought of the U.S. process of picking Yucca Mountain. He glibly replied that the U.S. didn’t use any rational decision-making process to speak of. </div><div style="text-align: left;"><br /></div>Of course we didn’t.<span> </span>Because in the U.S., we rarely let scientific and rational thought interfere with a decision that a politician could use to his or her own electoral benefit.<span> </span>The case of where to site our nuclear waste repository was no exception.<span> </span><p></p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal"><br /></p><p class="MsoNormal">The year was 1987.<span> </span>Three repository locations were on the table:<span> </span>Washington state (near the Hanford Nuclear Reservation site), salt formations in Texas, and Yucca Mountain in Nevada.<span> The Nuclear Waste Policy Act of 1982 </span><a href="http://www.law.cornell.edu/uscode/html/uscode42/usc_sec_42_00010132----000-.html"><span class="Apple-style-span" style="color:#000000;">called for an environmental assessment</span></a><span> of each of the three ca</span><span>ndidate sites, and for the president to choose a site to begin centralized storage.

In this area, we ought to act more like the British. If U.S. citizens could follow the steps of the decision-making process in a timely, organized way, they are more likely to accept the outcome of the process, whether that outcome is storage at Yucca Mountain, or some other location or method. </p><div style="text-align: left;"> </div><p></p><p class="MsoNormal"><br /></p><p class="MsoNormal">Right now President Obama's decision to drop Yucca Mountain from consideration holds just as much logic as President Reagan's decision to drop Texas and Washington state in favor of Yucca Mountain. By embarking on a process that is more inclusive of ideas and that seeks to educate the public as much as it does to gain their approval, President Obama could reverse years of public misconception and apprehension about dealing with spent nuclear fuel.</p><p class="MsoNormal"></p><div style="text-align: left;"> </div><div><br /></div>I'll end with some vintage Daily Show footage...but even Jon Stewart fails to grasp the inter-generational complexities that have gone into making Yucca Mountain the political stalemate that it is today:<p></p> <table style="font: normal normal normal 11px/normal arial; background-color: rgb(245, 245, 245); " cellpadding="0" cellspacing="0" width="360" height="353"><tbody><tr style="background-color:#e5e5e5" valign="middle"><td style="padding:2px 1px 0px 5px;"><a target="_blank" style="color:#333; text-decoration:none; font-weight:bold;" href="http://www.thedailyshow.com/"><span class="Apple-style-span" style="color:#000000;">The Daily Show With Jon Stewart</span></a></td><td style="padding:2px 5px 0px 5px; text-align:right; font-weight:bold;">Mon - Thurs 11p / 10c</td></tr><tr style="height:14px;" valign="middle"><td style="padding:2px 1px 0px 5px;" colspan="2"><a target="_blank" style="color:#333; text-decoration:none; font-weight:bold;" href="http://www.thedailyshow.com/watch/thu-may-9-2002/the-little-engine-that-could----kill-us-all"><span class="Apple-style-span" style="color:#000000;">The Little Engine That Could...

They've bought the rights to 114 MW of capacity, either to use themselves to power their 'definitely not evil' enterprises, or sell on the open market. <br /><br /> Google has been playing in the clean energy field for awhile, but this is their most serious financial move to date. The article quotes a Google spokesperson as saying the deal represents 350 - 450 million kWh annually...if google <a href="http://www.awea.org/faq/wwt_costs.html">paid $0.05/kWh</a>, the deal is worth $350 million - $450 million. Some serious cash, and it should be viewed as a strategic business move, not as a 'beyond petroleum' greenwashing ploy.<br /><br />I think these long term wind contracts are a good idea. Google gets power at a reasonable, guaranteed rate for 20 years and is protected against volatile and likely increasing electricity costs. The wind farm gets a guaranteed customer and doesn't have to worry about expiring tax credits, which means it can probably get cheaper financing. Most importantly, it shows other companies that wind isn't just for hippies or politicians, it can make economic sense. <a href="http://techcrunch.com/2010/07/20/apple-data-center/">Apple, you're next!</a>Rogerhttp://www.blogger.com/profile/06893990318191297037noreply@blogger.com0tag:blogger.com,1999:blog-1305485489754759960.post-63679690906096102742010-07-15T22:33:00.010-04:002010-07-16T11:03:10.322-04:00Small step for electric cars, giant leap towards killing BP's Macondo well<span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">Today's post is somewhat of a news roundup.</span></span><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">President Obama </span></span><a href="http://www.washingtonpost.com/wp-dyn/content/article/2010/07/14/AR2010071406046.html?hpid=topnews"><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">promoted electric vehicles</span></span></a><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"> at the opening of a battery factory in Michigan yesterday, while engineers finally </span></span><a href="http://www.washingtonpost.com/wp-dyn/content/article/2010/07/15/AR2010071500642.html?hpid=artslot"><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">stopped the oil gusher</span></span></a><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"> completely (albeit possibly not permanently) for the first time since it began nearly three months ago.</span></span><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">While Gulf wildlife is not out of the <strike>oil infested waters</strike> woods yet, this is a major step on the way to permanently stopping the uncontrolled flow of oil.

His speech clarified what we already knew...that the government is impotent to stop the spill, and we are all at the mercy of a gaggle of incompotent BP engineers.<br /><br />However, the real problem is that the government also has no way to stop the other gusher...America's oil use. The President talks up alternative technologies such as PHEVs and next gen biofuels, but these will not substantially cut oil use for at least a decade.<br /><br />The only short term way to dramatically reduce American oil consumption is to jack up the price, but mentioning a gas tax in DC is now as politically savvy as chanting "drill baby drill", and the President's speech avoided the topic like the plague.<br /><br />...<br /><br />With all of these issues swirling, I spent last week in Boulder Colorado, apparently the happiest place on earth. The first thing you notice in Boulder is the beautiful mountain vistas. The second is the funky smell emanating from the dozens of medical marijuanna dispensaries.<br /><br />Boulder's liberal medical marijuanna laws mean that obtaining a doctor's perscription for pot requires $200 and a slight cough. The town is reaping the benefits of the many Colorado University students suffering from 'chronic pain' by taxing the hell out of the bud. And slowly, the city is relying more and more on the funds to keep budgets afloat...and legalized marijuana is becoming a reality in Colorado.<br /><br />My proposition is this: liberal cities like Boulder make their crunchy citizens happy by dramatically increasing local gas taxes...by $3 or $4 / gallon... and offset the tax hike by lowering income taxes. The tax would be revenue neutral for citizens, but the income from travelers would fill city coffers.<br /><br />Naturally, the city would pressure it's neighbors to follow suit, so people don't fill up next door. Eventually the effort would gain steam, and gas tax hikes would become tenable at the state and federal level.<br /><br />The Boulder Chronic Model (BCM) is the best cure for America's chronic oil addiction.<br /><span style="font-style:italic;"><br />-------<br />Update, 7/20/10: </span>The NYT did a great story a few weeks back on the burgeoning Boulder marijuana business: http://www.nytimes.com/2010/06/27/business/27pot.html?pagewanted=allRogerhttp://www.blogger.com/profile/06893990318191297037noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-19904430019813929622010-06-10T10:36:00.005-04:002010-06-10T11:00:55.180-04:00Offshore Wind and Oil: BFFs in a new Federal BureauHere's a link to a <span class="blsp-spelling-error" id="SPELLING_ERROR_0">betterworld</span>.org post about <a href="http://www.brighterenergy.org/11780/news/wind/east-coast-states-pledge-to-develop-offshore-wind-resources/">offshore wind on the east coast</a>. Governors from ten East Coast states pledged to work together on exploration and development of offshore wind resources. The post also mentions Department of the Interior's new "Bureau of Ocean Energy Management." I hadn't heard of it before, but apparently it is a third of the new <span class="blsp-spelling-error" id="SPELLING_ERROR_1">trifecta</span> of bureaus replacing the Minerals Management Service. Here is a very under-hyped (in my opinion, maybe I'm just out of the federal energy loop) <a href="http://www.mms.gov/">Secretary Order</a> citing the formation of the Bureaus of Ocean Energy Management and Safety and Environmental Enforcement, and the Office of Natural Resources Revenue (the link goes directly to a <span class="blsp-spelling-error" id="SPELLING_ERROR_2">pdf</span> on the right hand side of the page, three items down). This effectively splits up the party responsible for ensuring offshore drilling ventures are safe from the one that collects the paychecks from the drilling profits. It sounds similar to the split of the Atomic Energy Commission back in 1974, forming one body responsible for the licensing and safety of nuclear plants (the Nuclear Regulatory Commission) and another responsible for the research and promotion of nuclear energy, now part of DOE. <div><br /></div><div>It will be interesting to see how one bureau handles the management of both wind energy (and possibly wave and tidal energy eventually) and drilling for oil.

It came as a surprise to me since growing up in the U.S., most (if not all) families had both a washer and a dryer, and if not there were laundromats. (Sidebar: I would question the logic of adopting clothesline drying in my hometown near Washington, DC since most warm months are accompanied by such high humidity that it would make line drying take about as long as drying your laundry in a bathtub full of hot water.) Line drying works amazingly fast when it is sunny and dry, though. And it is so satisfying to take dry warm clothes off the line that you know took absolutely no electricity to dry. (Maybe I derive satisfaction in different ways than most people, though. It's a possibility.)</div><div><br /></div></div></div><div><br /></div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_rE9Q4NBtdrE/S-Hmoh1aWVI/AAAAAAAAA-A/h6R4zEX0dcA/s1600/hang-laundry-TP-lg.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 250px; height: 320px;" src="http://4.bp.blogspot.com/_rE9Q4NBtdrE/S-Hmoh1aWVI/AAAAAAAAA-A/h6R4zEX0dcA/s320/hang-laundry-TP-lg.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5467905006556043602" /></a><br /><div><br /></div><div><div>However, there is one flaw in the plan. Much like winter seems to take Portugal by surprise each year (by my experience of n=1 years), two to three-week bouts of rain make line drying laundry difficult if not impossible during January, February, and March. My roommates and I would race to the washer at the first sign of a sunny day, keeping an eye on the weather report as we put our clothes out to dry, and more than once racing to pull them down as it became clear our luck with the sun had run out. During one particularly long rainy spell, where I had used up virtually all of my clean clothes, I decided to use a laundromat. But upon asking a few Portuguese how to do this, getting some blank looks and "what is a laundromat?" questions, my only other timely option was to go to a dry cleaners. This expedition cost me about 20 euros for the equivalent of 2 loads of laundry - washed, dried, and folded. Lesson learned. My advice: when you come to Portugal for the winter, make sure you bring plenty of clean underwear. Or, you might want to open a laundromat...you would have my business.</div></div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com0tag:blogger.com,1999:blog-1305485489754759960.post-67475654486830978372010-04-25T12:50:00.008-04:002010-04-26T05:56:39.291-04:00Welcome to Portugal Part ISuch a long time has passed between my last post and now, I'll give a quick life update first and offer lame excuses as to why I haven't been posting.<div><br /></div><div>In a nutshell, I'm in my second semester of a PhD program called Engineering and Public Policy through Carnegie Mellon University and Instituto Superior Tecnico-Lisbon. In January I moved to Lisbon, and in the interim I have worked to adjust to life in southern Europe and keep up with some demanding classes, which have left me with little energy or motivation for blogging.</div><div><br /></div><div>But that will all change as of now. It is not so much that courses have gotten easier or there is less work to do, but that I am so full of interesting things to say about energy in Portugal that I am bursting at the seams to let it out. So here it goes...</div><div><br /></div><div>Part I: What do you mean there's no heat?</div><div><br /></div><div>This wasn't exactly what I said to my landlady upon arrival, because I had been warned by students who came here last year that this was generally the way things were in temperate Portugal. Most of the year it's no big deal, but for a few weeks in January the temperature in Lisbon flirts with freezing, usually settling in at 3-4 degrees C overnight. This made my first days after my arrival January 9th somewhat of a shock. My landlady introduced me to the wonders of the hot water bottle and the art of wearing layers indoors. I met other students from different parts of Europe and they, too, found the lack of indoor heating something to get used to. Even students from Eastern Europe, no strangers to cold, complained about the weather constantly those first weeks (the cold, but also the relentless rain - also a trademark of Lisbon in January). In talking to them we decided the difficult thing to get used to was the lack of temperature difference between inside and outside. They, like me, were used to entering warm buildings during winter. The Portuguese, to their credit, are not. Despite spending nights clinging to the hot water bottle I rather like the fact that the Portuguese can endure a few weeks of being chilly during the winter while often the first frost in October-November prompts homeowners in the states to crank up their thermostats to 65 F (I'm being generous here...usually its more like 72 F). </div><div><br /></div><div>Well, this is part of the reason that <a href="http://www.blogger.com/www.eia.doe.gov/pub/international/iealf/tablee1c.xls">Portugal's per capita energy consumption in 2006 was less than one third that of the United States' (downloads an xls file),</a> and other reasons are forthcoming in subsequent parts of my newly christened "Welcome to Portugal" series.

A number of inches are dedicated to a potential scandal involving bid-rigging and the president of China National Nuclear Corporation, later noting that "</span></span><span class="Apple-style-span" style=" line-height: 22px; "><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">While none of Mr. Kang’s decisions publicly documented would have created hazardous conditions at nuclear plants, the case is a worrisome sign that nuclear executives in China may not always put safety first in their decision-making.</span></span></span><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">" Reading between the lines on that sentence, I'd say the NYT tried really hard to find a link from that scandal to safety, and finding none, decided to make everything hypothetical and run with it anyway. </span></span><div><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></div><div><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">Despite that segment, the article actually touches on an interesting trend in Chinese energy policy, which I happened to also hear about last night at a talk by Jeff Tolnar, the CTO of </span></span><a href="http://www.bplglobal.net/eng/index.aspx"><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">BPL Global</span></span></a><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">. His talk focused on smart grid technology, but within that mentioned how China prefers to do things from a centralized perspective (big surprise there), so for smart grid that means focusing on the supply side first. This paradigm fits with its nuclear ambitions as well: China plans to build 391 GW of new nuclear capacity by 2050, 61 GW of that by 2020. It currently has 9 GW. In comparison, the US has 100 GW of nuclear capacity today. Even if China meets its nuclear goal, the IEA projects that its emissions will grow "72 to 88 percent by 2020" according to the same NYT article. </span></span></div><div><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></div><div><span class="Apple-style-span" style="font-family:georgia;"><span class="Apple-style-span" style="font-size: medium;">So this has gotten me thinking, is China focusing on its large energy infrastructure because that is how its government functions best? Or would China actually be a very effective implementer of demand response and energy efficiency? (After all, if a government can tell you how many kids to have it could probably also be able to tell you what kind of light bulbs to use as well as when to use them.)</span></span></div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com0tag:blogger.com,1999:blog-1305485489754759960.post-47276300265712164872009-12-08T23:14:00.003-05:002009-12-08T23:34:44.510-05:00Copenhagen: Christmas in December for EnvirobloggersConsidering I've posted a few times on the lead up to Copenhagen, the rational blog reader would expect feverish updates right about now on all the goings-on of the summit.

While a strategic move by Chairwoman Senator Barbara Boxer (D-CA), this will no doubt leave a bad taste in the mouths of many Republicans when the bill finally screeches to a halt on the Senate floor for a full debate. </span></span><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">Now, ominously, Senator Lugar (R-IN) has emerged from a high profile meeting with UN Secretary General Ban Ki-moon, Sens. John Kerry (D-MA) and Joe Lieberman (I-CT) saying </span></span><span class="Apple-style-span" style="line-height: 18px; "><span class="Apple-style-span" style="font-size:medium;"><a href="http://voices.washingtonpost.com/capitol-briefing/2009/11/lugar_warns_democrats_i_dont_s.html?hpid=news-col-blog"><span class="Apple-style-span" style="font-family:georgia;">"I don't see any climate bill on the table right now that I can support</span></a><span class="Apple-style-span" style="font-family:georgia;">," which is really bad news for Democrats, because Sen. Lugar is one of a handful of Republicans who the Democrats were hoping would support the bill, as well as an influential member of his own party.</span></span></span></div><div><span class="Apple-style-span" style=" line-height: 18px;font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style="line-height: 18px; "><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">I was curious to know why he might oppose the bill, and after reading a recent </span><a href="http://lugar.senate.gov/press/record.cfm?id=307401&&"><span class="Apple-style-span" style="font-family:georgia;">speech</span></a><span class="Apple-style-span" style="font-family:georgia;"> of his I have a theory. Out of concern for potential crop shortages in developing countries (and likely also his home constituency) as a result of climate change, he is a proponent of genetically modified (GM) crops for increased productivity, which does not play a part in S.1733. (As some areas become more arid due to climate change, one negative effect could be decreased crop productivity. GM crops are one adaptation option to keep food supply steady for a growing population.) So perhaps it's the lack of this potentially beneficial climate change adaptation technique in the bill that's keeping his support at bay. However, the Obama administration </span><a href="http://www.gourmet.com/foodpolitics/2009/04/politics-of-the-plate-genetically-modified-foods"><span class="Apple-style-span" style="font-family:georgia;">does not seem to be opposed to GM crops</span></a><span class="Apple-style-span" style="font-family:georgia;">, keeping many former Bush policies on that matter in tact. So why would GM not find its way into S.1733 as a compromise? </span></span></span></div><div><span class="Apple-style-span" style=" line-height: 18px;font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style="line-height: 18px; "><span class="Apple-style-span" style="font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">One word: Copenhagen. Sen. Lugar even mentions it in his speech that the European Union is vehemently opposed to promoting GM crops, and the US wants to make a good impression when the </span><a href="http://unfccc.int/2860.php"><span class="Apple-style-span" style="font-family:georgia;">UNFCCC</span></a><span class="Apple-style-span" style="font-family:georgia;"> convenes in December in Copenhagen to hash out a successor treaty to the Kyoto Protocol.</span></span></span></div><div><span class="Apple-style-span" style=" line-height: 18px;font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;"><br /></span></span></div><div><span class="Apple-style-span" style=" line-height: 18px;font-size:medium;"><span class="Apple-style-span" style="font-family:georgia;">Well, that's probably part of the story, and just my theory.

Pragmatists, among whom I count myself, expound the importance of nuclear power expansion to supply near-zero carbon baseload power. Idealists think we can achieve an 80% reduction in CO2 emissions by mid-century by using renewables, smart grid, and happy thoughts.*</div><div><br /></div><div>An <a href="http://www.washingtonpost.com/wp-dyn/content/article/2009/10/27/AR2009102704081.html">article</a> today in the Washington Post illuminates how this debate is playing out on capitol hill, with Republicans weary of supporting any climate bill that leaves out significant incentives (such as federal loan guarantees and federal support for training workers at nuclear plants) for nuclear power. Interestingly, it seems the Senate's nuclear proponents are even more optimistic than those in the nuclear industry when it comes to the question of how many plants we can expect to build in the next 30-40 years: Senator Lamar <a href="http://en.wikipedia.org/wiki/Lamar_Alexander">Alexander</a> (R-TN) wants 100 new plants (doubling the nation's current capacity), while nuclear industry finance experts place the most optimistic estimates at around 50 by 2035.</div><div><br /></div><div>This leads to an interesting demand-side management problem: nuclear plants are designed to provide continuous baseload. With a much higher percentage of electricity coming from nuclear, utilities will need to find ways to utilize that power at night when demand is at its lowest. One option would be to install electric water heaters, a method France uses to absorb its electricity output at night (it uses upwards of 75% nuclear power). Another would be using that electricity to charge electric vehicles (more of a long term goal).</div><div><br /></div><div>Another interesting snippet from this article is that for nuclear to be a more attractive option than gas-fired plants, the price of natural gas must be above $7 per 1000 cubic ft. Right now, the price is about half that. The volatility of this price point notwithstanding (see figure), I thought it would be interesting to see what sort of carbon tax would be needed to make nuclear and gas-fired plants break even. With natural gas having an emissions coefficient of 116 lbs CO2/1000 cubic ft (from the <a href="http://www.eia.doe.gov/oiaf/1605/coefficients.html">EIA</a>) and a price of $3.5/1000 cubic ft, a carbon price of $60/ton would make nuclear the more attractive option for additional generating capacity development. And that includes a huge assumption about natural gas prices staying constant: accounting for the uncertainty in price would make nuclear the more attractive option with a much smaller (if any) carbon price.</div><div><br /></div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_rE9Q4NBtdrE/SuhETTj2VqI/AAAAAAAAAIw/BcKaGoUt1Ew/s1600-h/NGpriceEIA.jpg" style="text-decoration: none;"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 130px;" src="http://2.bp.blogspot.com/_rE9Q4NBtdrE/SuhETTj2VqI/AAAAAAAAAIw/BcKaGoUt1Ew/s320/NGpriceEIA.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5397639251862378146" /></a><div><br /></div><div><br /></div><div><br /></div><div>*The author apologizes to anyone she's offended with her snarkiness.</div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com2tag:blogger.com,1999:blog-1305485489754759960.post-86133096082706530902009-10-25T16:30:00.007-04:002009-10-28T09:52:30.514-04:00Human rights today, climate change tomorrow<p><a href="http://online.wsj.com/article/SB10001424052748704500604574481341183751038.html">A recent editorial in the Wall Street Journal</a> questions President Obama’s recent softening on human rights negotiations. Bret Stephens cites Obama’s refusal to meet with the Dalai Lama, softening positions on Sudan, Burma, and Iran as appeasement to China. Mr. Stephens feels the goal of these compromises is to get China at the table in <a href="http://en.cop15.dk/">Copenhagen for climate negotiations in December</a>.<br /><br />The claim is serious. Currently, there are <a href="http://en.wikipedia.org/wiki/Refugee#Climate_refugees">nearly a million</a> Sudanese refugees. Approximately <a href="http://www.tibet.com/exileglance.html">110,000</a> Tibetans live in exile. <a href="http://en.wikipedia.org/wiki/Burma">50 million</a> Burmese live under a brutally repressive regime.</p><p>However, Stephens never asks why Obama is making these sacrifices for climate change. He should have instead asked if preventing climate change is worth turning a blind eye to human rights abuses.<br /><br />Climate change will have a disastrous impact on human welfare. The <a href="http://www.ipcc.ch/pdf/assessment-report/ar4/wg2/ar4-wg2-spm.pdf">IPCC AR4</a> report states, “In the year 2000, climate change is estimated to have caused the loss of over 150,000 lives”. <a href="http://www.unep.org/Documents.Multilingual/Default.asp?ArticleID=5551&DocumentID=504&l=en#">Impacts will be higher in the future</a>: by 2050, the an estimated 133 million people will be at risk of hunger because of climate change. Decreased freshwater availability in Asia, due to melting glaciers, “could adversely affect more than a billion people by the 2050s”. And by the end of the 21st century, climate change will increase the number of people flooded in coastal populations by 80 million.<br /><br />Enough of the scary forecasts. Bottom line: climate change is expected to increase the suffering of hundreds of millions of people. The real question is: how much are we willing to increase suffering today to reduce suffering tomorrow?<br /><br />An easy answer is that we’re not willing to compromise at all on human rights. Human rights compromises lead to a slippery slope that undermines our moral character. Although this is a noble position for an individual to take, it is an impractical position for the U.S. government. International diplomacy requires compromise. Not compromising equals inaction, which will increase suffering from climate change.<br /><br />Economists deal with this problem by discounting future lives, just as you discount the costs of future purchases because of inflation. OMB suggests federal agencies adopt a <a href="http://www.ombwatch.org/node/1213">3% discount rate </a>on statistical lives for regulatory policies that impact human health.<br /><br />A 3% discount rate means 15 million deaths in 2009 equal 50 million deaths in 2050 and 122 million in 2080. Are we willing to sacrifice the human rights of 15 million today to prevent the suffering of 50 million in 2050? How should we, as a society, value future human lives?</p>Rogerhttp://www.blogger.com/profile/06893990318191297037noreply@blogger.com4tag:blogger.com,1999:blog-1305485489754759960.post-24797283407988625142009-09-24T16:30:00.005-04:002009-09-24T21:27:38.855-04:00An End to Fossil Fuel Subsidies?<span style="font-style:italic;">Simon writes each week on international issues relating to energy policy.</span><br /><br />Among the most recent grand ideas to emerge in the pre-Copenhagen scrum is <a href="http://www.ft.com/cms/s/0/2b82d566-a86a-11de-9242-00144feabdc0.html">this</a> from the US administration. President Obama has thrown his backing behind a plan to ban all government subsidies of fossil fuels, everywhere in the world. <br /><br />It is a plan with considerable merit. New forms of electricity generation are constantly called on to prove themselves economically - a difficult enough task without their fossil fuel competition receiving both implicit and explicit subsidies in many countries. <br /><br />However, fossil fuel subsidies are used to achieve a variety of policy objectives, and their removal will leave governments having to work out how to replace them. In the developing world, especially oil-producing countries, though they distort consumption patterns, they can be a more effective way of transferring wealth to the population. After all, in nations bedeviled by corruption, the choice is often not between cheap fuel and other government services, but between cheap fuel and embezzlement. In non-producing LDCs, subsidized fuel is not a perk for the very poorest, but can facilitate simple entrepreneurial activity - being able to run a tractor to improve land's productivity or have a generator so a factory no longer depends on unreliable municipal electrical utilities.<br /><br />In the developed world, meanwhile, programs such as the <a href="http://www.acf.hhs.gov/programs/ocs/liheap/">Low Income Home Energy Assistance Program (LIHEAP)</a> in the US or Britain's <a href="http://www.thepensionservice.gov.uk/winterfuel/">Winter Fuel Allowance</a> program, fuel subsidies are a standard form of redistribution to the poor or elderly. Abandoning these programs risks leaving vulnerable communities bearing the brunt of switching to more efficient energy production. <br /><br />Meanwhile, the tax breaks, competition protection and generous regulatory environments that western governments offer for a variety of industries, including oil and gas exploration and drilling, electricity generation and utilities could all come under pressure from the new agreement.<br /><br />I think the idea is a good one - removing government subsidies for big business and polluting fuels is a necessary step towards leveling the marketplace for energy production and nurturing the next generation of energy solutions. However, as with almost all the big ideas in energy these days, the political obstacles are going to be large, with influential industry and citizen groups both being affected. Having resolved the question of what to do, it'll be interesting to see how to make it happen.Simonhttp://www.blogger.com/profile/12602265056226581605noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-56357861691537624202009-09-17T09:50:00.008-04:002009-09-17T11:06:32.043-04:00You have a nice day too, Mr. Friedman<span class="Apple-style-span" style="font-size:medium;">I've been mulling over an </span><a href="http://www.nytimes.com/2009/09/16/opinion/16friedman.html?_r=1"><span class="Apple-style-span" style="font-size:medium;">Op-Ed</span></a><span class="Apple-style-span" style="font-size:medium;"> by well-known economist Thomas Friedman for the past few days. To summarize, Mr. Friedman visits Applied Materials' Silicon Valley headquarters and bemoans the fact that all of their solar panel production facilities are located abroad (in Germany, Taiwan, Spain, Italy, Abu Dhabi, India, and China, to be precise) and therefore the U.S. is doomed to become an importer of solar panels from China, thus repeating the vicious cycle of being beholden to another area of the world for our energy needs for decades to come. Well, there it is. Global competitiveness: doomed. National security: doomed. </span><div><span class="Apple-style-span" style="font-size:medium;"><br /></span></div><div><span class="Apple-style-span" style="font-size:medium;">Fear not. As you may have gleaned from my tone, I don't entirely agree with Mr. Friedman's assessment of the situation and here's why:</span></div><div><span class="Apple-style-span" style="font-size:medium;"><br /></span></div><div><span class="Apple-style-span" style="font-size:medium;">One of his major points is that the solar industry needs clear and stable policy signals and he references Germany's feed-in tariff system as a way to do that. I completely agree but Mr. Friedman is putting his cart (solar PV) before his horse (the electricity grid). Any major policy effort to increase significantly the amount of variable electricity generation feeding into the grid will first require an overhaul of how the grid operates and interacts with external power sources. </span><a href="http://energy.ihs.com/News/renewable-energy/2009/doe-solar-energy-grid-security-083109.htm"><span class="Apple-style-span" style="font-size:medium;">This</span></a><span class="Apple-style-span" style="font-size:medium;"> needs to happen first. Even more challenging will be your average Joe Megawatt who wants to sell his excess power back to the grid: this isn't </span><a href="http://www.gap.com/"><span class="Apple-style-span" style="font-size:medium;">The Gap</span></a><span class="Apple-style-span" style="font-size:medium;">, people, returning electricity isn't free. It takes extra modifications and operational planning. If all of this isn't optimized then feeding in Mr. Friedman's "zero variable cost" renewable energy could cost more in terms of dollars and emissions than the "do nothing alternative."</span></div><div><span class="Apple-style-span" style="font-size:medium;"><br /></span></div><div><span class="Apple-style-span" style="font-size:medium;">Another problem I have with the article is his singular focus on solar PV and sometimes wind. He states, "</span><span class="Apple-style-span" style=" line-height: 22px; "><span class="Apple-style-span" style="font-size:medium;">The world is on track to add another 2.5 billion people by 2050, and many will be aspiring to live American-like, high-energy lifestyles. In such a world, renewable energy — where the variable cost of your fuel, sun or wind, is zero — will be in huge demand.</span><span class="Apple-style-span" style=" line-height: normal; "><span class="Apple-style-span" style="font-size:medium;">" Not true. </span><i><span class="Apple-style-span" style="font-size:medium;">Energy </span></i><span class="Apple-style-span" style="font-size:medium;">will be in high demand, and most people won't be thinking about whether it came from a solar panel or a nuclear power plant. So let's not lose focus on the big picture and all the other options (carbon capture, nuclear power, geothermal, hydro) out there for providing low-carbon reliable, baseload electricity. And let's not forget that many of these low-emissions alternatives to solar panels are being developed and built right here in the USofA.</span></span></span></div><div><br /></div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-53471638292036793542009-09-15T20:10:00.003-04:002009-09-15T20:15:03.357-04:00The Hydrogen Challenger<!--StartFragment--> <p class="MsoNormal">A couple days ago I was cruising the internet and stumbled across something interesting: the <a href="http://en.wikipedia.org/wiki/Hydrogen_Challenger">Hydrogen Challenge</a>r.</p> <p class="MsoNormal">The Hydrogen Challenger is a tanker ship that has been refitted with wind turbines and an electrolyzer to make hydrogen.<span style="mso-spacerun: yes"> </span>The ship cruises out to the open sea where the wind blows the hardest, anchors for awhile and fills up with hydrogen, then cruises back to port and unloads the hydrogen.</p> <p class="MsoNormal">At first I thought this was a weird idea cooked up by someone with too much money, or maybe another Rainbow Warrior.<span style="mso-spacerun: yes"> </span>But at a second glance, I think it may be an idea ahead of its time.<span style="mso-spacerun: yes"> </span>Compared to the most similar alternative, offshore wind turbines, it has several advantages.</p> <p class="MsoNormal"><i>Higher wind speed</i>s: The best wind resources on land are about 9 m/s.<span style="mso-spacerun: yes"> </span>A mile or two offshore, where offshore wind turbines are located, the wind blows at about 13 m/s.<span style="mso-spacerun: yes"> </span>The Hydrogen Challenger can go further from the coast than offshore turbines, where wind speeds approach 20 m/s. The power delivered from a wind turbine increases by the wind speed cubed, so the same turbine could deliver almost four times the power if its on the Hydrogen Challenger instead of stationed offshore.</p> <p class="MsoNormal"><i>Higher Capacity Factor</i>: A wind turbine only generates electricity when the wind blows, and when people want to buy its electricity.<span style="mso-spacerun: yes"> </span>A lot of times, turbines generate power when it isn’t needed, such as at night, so the power is wasted.<span style="mso-spacerun: yes"> </span>The Hydrogen Challenger stores energy in hydrogen, so the generated power is never wasted.</p> <p class="MsoNormal"><i>Storage and Markets</i>: Unlike electricity, hydrogen can be stored in large quantities and for long periods of time.<span style="mso-spacerun: yes"> </span>Storing energy in hydrogen allows the generator to sell power only when and where the price is highest.<span style="mso-spacerun: yes"> </span>This means that every kWh of hydrogen energy is much more valuable than a kWh of electricity.</p> <p class="MsoNormal"><i>Transmission</i>: Although it seems impractical to retrofit barges with wind turbines, I bet it is cheaper than running undersea electric lines to offshore power turbines.<span style="mso-spacerun: yes"> </span>Undersea electric lines are very expensive, ranging from $20,000 - $80,000 /MW-km.<span style="mso-spacerun: yes"> </span>Sources say transmission costs are 10% - 20% of total cost for offshore wind farms.</p> <p class="MsoNormal">I think the Hydrogen Challenger is a good idea that we’ll see more of in the future, but there are some problems that will need to be addressed:</p><p class="MsoNormal"><i>Electrolyzer cost / efficiency</i>: Electrolyzers are expensive and inefficient (~70%).</p><p class="MsoNormal"><i>Storage</i>: To generate as much power as possible, the barge should stay at sea generating power as much as possible and minimize unloading trips.<span> </span>A barge may not have enough volume to store the amounts of hydrogen generated.</p><p class="MsoNormal"><i>Wind Speed</i>: Curiously, no commercial wind turbines today can handle the 20 m/s winds hydrogen barges would see…most max at 13 m/s.</p><p class="MsoNormal"><b><i>Shipwreck!</i></b>: The top heavy barge can't capsize in a storm.</p><p class="MsoNormal">An interesting concept.<span style="mso-spacerun: yes"> </span>What do you think…will we see fleets of pirate turbine-barges trolling the open seas in the future?</p> <!--EndFragment-->Rogerhttp://www.blogger.com/profile/06893990318191297037noreply@blogger.com4tag:blogger.com,1999:blog-1305485489754759960.post-38310045795166883092009-09-01T19:33:00.004-04:002009-09-01T19:55:44.010-04:00Innovative idea of the day: space-based solar energyWhile the idea of capturing solar energy in space and transmitting it back to earth has been around for decades, it seems the <a href="http://www.bloomberg.com/apps/news?pid=20601101&sid=aJ529lsdk9HI">idea is gaining traction in Japan</a> as well as within the U.S. government (see the topic mentioned on the change.gov website <a href="http://change.gov/open_government/entry/space_solar_power_ssp_a_solution_for_energy_independence_climate_change/">here</a> and the 2007 National Security Space Office report <a href="http://www.acq.osd.mil/nsso/solar/solar.htm">here</a>).<div><br /></div><div>There are a lot of potentially interesting hurdles to explore with respect to this extremely nascent technology, but I'd like to focus on the contrast between the Japanese and U.S. approaches to space-based solar for a minute. </div><div><br /></div><div>First, notice the dollar (or yen) figures involved. The U.S. has spent $80 million over three decades studying the feasibility of space-based solar (SBS). Japan has committed the equivalent of $21 billion (over <b>260</b> times what the U.S. has spent) to develop and build a SBS station over the next three decades. So it seems likely that if SBS ever becomes reality, the U.S. will be an importer (and whether that's bad is another discussion on global competitiveness I can save for a later date).</div><div><br /></div><div>Also, Japan has immediately brought its <a href="http://www.bloomberg.com/apps/quote?ticker=6503%3AJT">heavy</a> <a href="http://www.bloomberg.com/apps/quote?ticker=7013%3AJT">hitters</a> to bat for this technology, while the U.S. allocated a study to DoD's obscure (but nonetheless effective and important) National Security Space Office. In sum, the U.S. ought to get its proverbial toe out of the water and decide whether to dive in with Japan or go find another pool to play in when it comes to advanced renewable energy ideas.</div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-24631427223858423652009-08-27T23:02:00.003-04:002009-08-28T01:06:05.212-04:00Sinn oder Unsinn...<span style="font-style:italic;">Simon writes each week on international issues relating to energy policy.</span><br /><br /><a href="http://www.ft.com/cms/s/0/2992000e-92a0-11de-b63b-00144feabdc0.html">Writing </a>in the <span style="font-style:italic;">Financial Times</span> this week, German professor Hans-Werner Sinn describes what he terms "the green paradox" ("a green paradox" might have been more suitable, but that's beside the point). By this, he means the unfortunate consequences of future policy to limit carbon emissions being to encourage producers to extract more oil, gas and coal today, before their costs are increased. His solutions: a perfect, "seamless" global emissions cap (easier said than done) or a punitive tax regime on producers (a Sinn Tax?).<br /><br />How the latter is supposed to operate is a mystery. Who is going to be able to tell Saudi Arabia to hand over the $69 profit it makes on a $70 barrel of oil as a matter of international law? No organization that currently exists could do it, and can't image one that could without giving rise to very serious concerns about democratic accountability and liberty that would outweigh any environmental benefit. It is also worth noting that, with the price of oil in Sinn's vision still high, temptations to cheat would be rampant. From OPEC through the Iraqi Oil for Food program, history has shown attempts - even internationally sanctioned attempts - to compel countries to stop producing their only revenue source to be destined for failure.<br /><br />The carbon cap, improbably, seems the more viable of Sinn's proposals. But the only way that it will work is the only way that any demand management strategy (most of which he appears to loath) works. The prices for substitutes have to come down. This straightforward observation is completely absent from his argument, but is crucial to it. Without functional and affordable alternative technologies, all the king's horses and all the king's men couldn't keep people from wanting energy products, and the countries that have them from supplying them. A cap changes the definition of what's affordable, moving the equilibrium from, nominally, the cost of producing oil to some other, policymaker-set value. But it doesn't change the fundamental; that unless there's some other way of powering the lights, that oil, coal and gas is going to be produced and combusted.Simonhttp://www.blogger.com/profile/12602265056226581605noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-12217171317705824352009-08-23T12:15:00.004-04:002009-08-23T12:25:44.122-04:00Climate Science, Politics and Kurt Vonnegut<!--StartFragment--> <p class="MsoNormal" style="line-height:19.0pt;mso-pagination:none;mso-layout-grid-align:none;text-autospace:none"><span class="Apple-style-span" style="line-height: normal; "><i> "Here's what I think the truth is: We are all addicts of fossil fuels in a state of denial, about to face cold turkey."</i> Kurt Vonnegut, Jr.</span></p> <p class="MsoNormal">Research in the field of global climate change has made significant strides in the modern era. Paleontologists have used history to test and refine new concepts, advanced spatial and temporal models have allowed us to make long-term predictions, and socio-economic analysis of climate change impacts have all served to bring the issue into the political domain. The role of research (basic and applied) in bringing climate change to the political domain can not be understated. Without trust in the scientific method, climate change would have faltered as environmental propaganda from the get-go. Notice the emphasis on the <i>scientific method</i><span style="font-style:normal"> and not simply the science or science-based results. More on this in a moment.</span></p> <p class="MsoNormal">And so in time, climate change has been labeled environmental propaganda because the scientific arguments which at first held so much weight, have over-stayed their welcome and been uttered too many times by politicians. Politicians concluded more and new science was needed. In response, a portion of the scientific community and some politicians formed an unwritten agreement that science would attempt to advance a political agenda much as science originally placed the issue on the political agenda. To my mind, this has manifested itself most directly in the pursuit of climate proof, which often takes the form of tying weather events and climate trends to climate change. </p><p class="MsoNormal"><o:p></o:p></p> <p class="MsoNormal">Today we see a variety of researchers in the field of global climate change including honest brokers of climate policy alternatives, genuinely pure climate scientists, and issue advocates (both admitting and non-admitting) (see Roger Pielke, Jr. for more). I do not object to advocacy or politics in research as I believe the portrayal of science as objective is an illusion – no scientist operates in a vacuum free of values. What I do object to, and this is my motivation for contributing to this blog, is a failure to recognize the clout science holds lies less in its ability to generate new knowledge or even the purported objectivity of science, and more in the scientific method.</p> <p class="MsoNormal">There is no process of truth-seeking more logical than the scientific method. A testable and falsifiable hypothesis is formed, the hypothesis is tested and subsequently refuted or upheld, and an independent researcher reproduces the results. In other words, hypotheses are to be disproved and never proved. To me, the scientific method is holy because it says humans can never know any aspect of nature in its entirety and this is <u>fucking exciting</u>. A scientist seeking to prove a hypothesis simply isn’t using the scientific method and does not have the power of the scientific method on his/her side.</p> <p class="MsoNormal">I feel its time to draw some conclusions. 1 – At this stage in the game of climate politics, it seems like only proof will push the boulder over the hill. Don’t be fooled. 2 –The scientific method can’t generate proof, but it garners respect and is not to be ignored. So use it. 3 – Start listening to climate skeptics instead of always convincing them. Become a skeptic yourself on points that don’t sit well. 4 – Scientists and researchers should stop trying to build evidence and proof of climate change and instead cull and refine the hypotheses, models, and predictions already out there. Time should assist in re-evaluating past research, if only we make time (and funding) for it.<o:p></o:p></p> <p class="MsoNormal"><i> "Another flaw in the human character is that everybody wants to build and nobody wants to do maintenance."</i> Kurt Vonnegut, Jr. </p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:TimesNewRomanPSMT, serif;"><br /></span></p> <!--EndFragment-->Sean Williamsonhttp://www.blogger.com/profile/18131092640573071700noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-64787653756289035212009-08-20T03:43:00.005-04:002009-08-20T04:11:04.547-04:00Can lithium aid Bolivia's depression?<span style="font-style: italic;"></span><span style="font-style: italic;">Simon writes each week on international issues relating to energy policy.</span><br /><br /><br />Twice in the space of the past day, I encountered an energy story I'd never come across before. The story provides a glimpse of a potentially vast revenue stream for a highly impoverished country, but is accompanied by some warnings from history. It features a Latin American nation often overshadowed by its more truculent or troublesome neighbors to the north – Bolivia. It also features the lightest metal in existence, and perhaps the critical ingredient in the electric-car revolution – lithium. <br /><br />Bolivia is home to the world’s largest salt flats, and these salt flats are in turn home to the world’s largest lithium deposits – <a href="http://news.bbc.co.uk/2/hi/business/7707847.stm">by some accounts 50% of all the world’s lithium</a> is located in the high, hot Uyumi plateau. And, as demand for the metal is driven up by battery makers, for use in laptops, longer life AAs, and increasingly by carmakers, the Bolivian government is looking to develop this heretofore-untapped resource. President Evo Morales’ Socialist government has determined that the state will take sole responsibility for the new mining operations, speaking in grandiose terms about being not just the “Saudi Arabia of lithium” – extracting the metal for wholesale – <a href="http://news.bbc.co.uk/2/hi/programmes/from_our_own_correspondent/8201058.stm">but of becoming the world’s leading battery manufacturer</a> . Such ambitions are bold, but also risky, as many commodity-dependent economies can attest.<br /><br />The historical record in such situations is not good. The concept of the “Resource Curse” is well established, as the likes of <a href="http://www.earth.columbia.edu/articles/view/1804">Jeffrey Sachs</a> and <a href="http://en.wikipedia.org/wiki/Paul_Collier">Paul Collier</a> have expounded. Excessive dependence on one industry can skew economic allocations, engender corruption and sometimes violence, and inhibits growth. Still, while the problems are well-known, solutions are hard to find. The alternative, ignoring – or at least underutilizing – natural resources won’t help growth either, and may be morally indefensible in a country where 60% of people already live below the poverty line. The jobs and income quality development would provide would be invaluable, especially among the indigenous communities who inhabit the salt flats, and whose income levels are markedly lower than people in other parts of the country.<br /><br />As prices continue to rise, it is going to become harder to hold off developing these deposits. It seems inevitable that despite Morales’ ideological hostility, there will have to be some involvement from foreign companies. While he can maintain ownership of the resources and their rents, Bolivia simply lacks the expertise, not to mention the capital, to realize their prospects. The treatment of western oil and gas companies in the last few years, summarily nationalizing and expropriating their assets, will have done little to encourage involvement, though. <br /><br />Of the possible solutions suggested <a href="http://www.globalpolicy.org/component/content/article/198/40112.html">here</a>, one of the more interesting – and implementable – ideas may be one from close(ish) to home. Privatization is out for the time being, simply because it is incompatible with the current politics of the country. Whether or not it would have much success is also questionable, with instances such as the former USSR showing it to be easy to get devastatingly wrong. Creating a Norway- or Dubai-style sovereign wealth fund to take proceedings and invest them in other sectors, to provide a longer-term and diversified revenue stream. Such funds, though, are only as responsible as their governors, and it is hard to tell how accountable the Bolivian government would be. But the third, slightly familiar idea, that of establishing a revenue distribution fund, similar to Alaska’s program for distributing oil proceeds, may be the most preferable. It reduces the dangers of corruption by putting money in the hands of citizens rather than the government. It helps raise individual incomes, allowing for the expansion of other private enterprises. The risks of inflationary pressures exist, but are probably no worse than other forms of distribution of the revenues, and with this system would have the added advantage of helping less well-off parts of society rather than waiting for a trickle-down from elites (which would have the added risk of capital flight).<br /><br />There are a lot of ifs to be addressed before we see this experiment take shape – at present prices this windfall is still minor, compared with the lucre that hydrocarbon fields provide (the value of Bolivia’s lithium amounts to about two thirds of its current GDP. By contrast, Saudi Arabia’s proven oil reserve are valued at around 40 times its current GDP, and Venezuela’s at around 20x). However, if electric cars expand their market share, and if lithium batteries remain the technology of choice to power them, the price of their commodity should continue to climb. Bolivia may well provide an interesting test case for a country trying to handle a new bounty of natural resources, using all the experience economists have learned from the previous century.<br /><br />With energy resources having proven the most egregious contributors to the “resource curse” problem through the years, and with the desire to re-invent the sector potentially generating new demand spikes for previously neglected materials, it behooves policymakers to ensure that the mistakes of the past are not repeated in the present. Efficient development need not be irresponsible development, and the owners of such resources, be they public or private, can give extractive operations a better reputation in the this century than they had in the last one.Simonhttp://www.blogger.com/profile/12602265056226581605noreply@blogger.com0tag:blogger.com,1999:blog-1305485489754759960.post-48273121867628985362009-08-17T10:09:00.004-04:002009-08-17T10:20:55.654-04:00Moores Mill Road Follow-up<span class="Apple-style-span" style="font-family:'trebuchet ms';">On Friday I promised an explanation for the strange behavior of the power lines on Moores Mill Rd. Basically what happened was a malfunction at a transformer substation that is in charge of stepping down the voltage from 34 kV to 14 or 7 kV.

So rather than delivering electricity at 7 kV (around that) to the transformers, they were getting inputs at 34 kV, the highest voltage considered to be distribution-grade electricity (above that is transmission). One by one the transformers were overloading and exploding (partially due to the insulating oil that is used inside them), and then the electricity would reach the next transformer in sequence. </span>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com1tag:blogger.com,1999:blog-1305485489754759960.post-69181572215539837592009-08-14T08:58:00.005-04:002009-08-14T09:12:42.132-04:00Friday YouTube Treat<span class="Apple-style-span" style="font-family:'trebuchet ms';">Good morning energy blogosphere. My post today will be short and sweet. Yesterday I visited a <a href="http://www.bge.com/portal/site/bge/">BG&E</a> distribution training center (where they train the people who go out into neighborhoods to put up or repair electric wires). Besides being a national leader in smart grid <a href="http://www.bge.com/portal/site/bge/menuitem.538792730c68ac667e1e1c10016176a0/">pilot programs</a>, they have a really well-oiled training system. They show this video to all of their trainees to let them know what happens when multiple things go wrong:</span><div><span class="Apple-style-span" style="font-family:'trebuchet ms', fantasy;"><br /></span></div><div><span class="Apple-style-span" style="font-family:'trebuchet ms', -webkit-fantasy;"><span class="Apple-style-span" style="font-family: Arial, sans-serif; font-size: 10px; white-space: pre; "><object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/Dmy9CHCewtg&hl=en&fs=1&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/Dmy9CHCewtg&hl=en&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object></span></span></div><div><span class="Apple-style-span" style="font-family:Arial, sans-serif;font-size:85%;"><span class="Apple-style-span" style="font-size: 10px; white-space: pre;"><br /></span></span></div><div><span class="Apple-style-span" style="font-family:'trebuchet ms', -webkit-fantasy;">I'll let you mull it over this weekend on what might have caused such a light show, and post an explanation on Monday. </span></div>colleenhttp://www.blogger.com/profile/16404462293985480565noreply@blogger.com2tag:blogger.com,1999:blog-1305485489754759960.post-84760527312978416562009-08-14T08:19:00.003-04:002009-08-14T08:28:06.207-04:00Newsflash:The world's running out of oil (tomorrow).
