Last month the Department of Interior (DOI) Bureau of Land Management (BLM) held its first competitive auction for commercial solar development on public lands, offering three parcels for lease with a collective acreage of 3,700 in the San Luis Valley of Colorado. The three leases are located in two of DOI’s designated “Solar Energy Zones,” which the DOI carved out for quick solar development due to access to existing transmission, limited environmental impacts, and cheap land rental.
If fully developed, these two Solar Energy Zones could potentially produce 400 MW of energy, enough to power an estimated 125,000 homes. Unfortunately DOI was alone in their enthusiasm as the auction drew zero bids from solar companies. Moving forward, DOI should learn from this initial failure and expand its Solar Energy Zones to also act as a test bed for next-generation clean energy designs, not just off-the-shelf technologies.
The Energy Experts Reconvene at the WSJ
Generally when I find myself having to write a follow-up post to something I wrote, it’s because I obviously didn’t make my points clearly enough. I found this to be the case during a lively Twitter discussion following my latest contribution to the Wall Street Journal’s (WSJ) Energy Experts Panel. But I love these sorts of discussions because they help me hone the message I am trying to deliver.
This week the WSJ began publishing the latest round of answers to questions that were submitted to their energy panel several weeks ago. The first question answered this week was: What is the single biggest misconception people have about renewable energy in the U.S.?
First, if you don’t know about the WSJ Expert Panels, I explained that in some detail here. Essentially, the WSJ has groups of experts in different fields, and they pose questions on various topics. We are asked to write ~ 300-word answers to these questions, which often means leaving out caveats and/or clarifications. The answers are more detailed than the 140 characters allowed by Twitter, but some topics leave a lot of issues unaddressed with just a 300-word answer. CONTINUE»
Today I begin a series that looks at the recently released 2013 BP Statistical Review of World Energy. Because the past two posts have dealt with the Keystone XL pipeline project, I thought it would be a good change of pace to kick off this series by looking at the current global picture of renewable energy. Additional articles in the series will examine the world’s fossil fuel consumption and carbon emissions.
Overall, renewable energy once more displayed very strong growth in 2012. Renewable energy accounted for 2.4% of global energy consumption in 2012, and a record 4.7% of global power generation.
The only renewable energy sector that stagnated in 2012 was the production of biofuels. For the first time since 2000, global biofuels production declined. This decline was primarily a result of a 4.3% drop in the production of biofuels in the US (but I expect production will be higher for 2013).
An Oft-Used Energy Slogan
Last week, Real Clear Politics and API hosted an energy summit in Washington, DC entitled, “Fueling America’s Future”. It was intended to provide a quick overview of most of the key technologies and issues associated with an all-of-the-above energy strategy for the United States. Going through the highlights of the webcast gives me an opportunity to introduce my point of view to a new audience at Energy Trends Insider. I’d sum that up as “All of the Above”, with asterisks for the proportions and situations that make sense.
This slogan, at least in the manner in which it has been espoused by politicians in both parties, has attracted fair criticism for being overly bland and safe. I suspect that critique reflects a general sense that our energy mix has always been composed of all of the above, or all of the technologies that were sufficiently proven and economic to contribute at scale at any point in time. However, as both our technology options and choice criteria expand, our understanding of the evolving energy mix is hampered by metrics and assumptions that are overdue to be revisited.
Mike is a true clean energy entrepreneur, starting way back with a fuel cell start-up in the late 1990s, he’s run a venture capital firm, been an executive at a solar company and founded another solar company… and he’s voting for Mitt Romney.
I was rebutting a comment I found under a CER News Desk article titled: Utility Head: Japan Can’t Afford Renewable Energy, Needs Nuclear when I realized I had generated enough material for an article.
Although not a single talking point in the comment I addressed is novel (few thoughts are), and not a single footnote to a source was proffered, the comment serves a larger purpose by providing me an opportunity to express some critical thought.
I don’t want the commenter to feel singled out and welcome him to continue to participate, but I would also like to suggest that he take the time to provide links to sources so the audience knows who the originators of the talking points are and so they can assess the quality of the sources of the information he passes along. I know of one site that does not allow unsourced comment. I don’t think this is necessarily a good idea because it has a tendency to spill over into censorship. They do this in an attempt to keep the comment field from becoming a come-one-come-all liar’s club (although most people are inadvertently passing along information they don’t realize — or care — is bunk).
Here is the link to my comments.
A new power grid based around renewable energy will cost Japan $622 billion to build, according to government estimates
With Japan in the process of rebuilding the infrastructure damaged during 2011′s devastating tsunami, many in the country are suggesting that the time is right for a transition from nuclear to renewable energy in that country. Fears of nuclear disaster fueled by the damage and subsequent radioactive leak at the Fukushima nuclear reactor after the tsunami have many groups, both private and public, clamoring for an immediate shutdown of Japan’s nuclear program.
Despite public pressure, though, many politicians recognize that the cost for Japan to move away from dependance on nuclear energy would simply be too high.
The continued existence and expansion of human civilization is wholly dependent on affordable sources of energy. The latest study just released by the National Renewable Energy Laboratory (an organization that exists to study and promote the viability of renewable energy) suggests that it may be possible to get 80% or so of our electric power from renewable sources by 2050. The study also (inadvertently) provides evidence that renewable energy will be a minority player in humanity’s energy portfolio.
The results may disappoint my fellow solar enthusiasts because it suggests that only 13% of our electric energy will come from solar. Distributed solar enthusiasts (who favor photovoltaic solar panels on rooftops) will be further disappointed because half of that 13% will come from water-sucking centralized concentrated solar thermal power plants, many located in desert ecosystems, leaving only about 6% for solar panels on rooftops, of which many will probably not be on rooftops but in centralized power plants, probably displacing ecosystems or crops.
Today’s article is the 5th and final installment of my graphical look at the recently released 2012 BP Statistical Review of World Energy. Previous installments were:
- How Much Oil is Left in the World?
- How Much Oil Does the World Produce?
- World Energy Consumption Facts, Figures, and Shockers
- Global Carbon Dioxide Emissions — Facts and Figures
Today’s article looks at the explosive growth of renewable energy, but also places it in the context of our overall energy demands.
Rapid Rise in Biofuels Production — U.S. Takes the Lead
The first graphic shows the rapid rise in global biofuel production that has occurred in the past decade — led by the United States. CONTINUE»
