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»
Why is Germany planning to phase out nuclear power? In a nutshell, because they fear it — self-serving behavior based on irrational fear. They’re doing it because a sufficient number of German citizens have been convinced by the fear tactics used by the anti-nuclear lobby that their nuclear power poses a significant safety risk (which it doesn’t).
They will be removing from the European grid their low emission nuclear power exports while simultaneously increasing the use of fossil fuels domestically in addition to using more from the E.U. grid, which is almost entirely nuclear and fossil fueled. They are counting on that power from the E.U. grid to fill in the gaps inherent in their own renewable power. To meet their goal of 100% renewable they would have to isolate themselves from the European grid.
My new book — Power Plays: Energy Options in the Age of Peak Oil — has been published. A press release issued last week describes the book in some detail:
Here I want to describe a bit about the evolution of the book, discuss what’s in it, and finally provide contact information for reviewers who would like a copy.
It was less than a year ago that I was contacted by Jeff Olson, a Senior Editor at Apress, which is a division of the large global publisher Springer about writing “a book for educated laypeople on today’s energy issues.” I had been contacted a couple of times previously about writing a book, but the timing wasn’t right for various reasons. This time, I felt like I could pull it off, and around the first of August 2011 I actually sat down to write the first words. Eight months and 272 pages later, it was published. CONTINUE»
Battle Over the Definition of Success in the ‘Cleantech’ Industry This past week PayPal co-founder Peter Thiel — who was also an early investor in Facebook — made headlines when he declared that “Cleantech is an increasingly large disaster that people in Silicon Valley aren’t even talking about any more. The failure in energy and transportation points to a larger failure in clean energy — we aren’t moving any faster, literally, than we were when modern airplanes first came out.” Those comments ruffled the feathers of Cleantech VC Vinod Khosla, who responded “Cleantech is not a disaster.” So who is correct? It depends entirely upon how one defines success: Over the last 12 months, Khosla has generated more than $1… Continue»
The following is a guest post from Andrew Smolski of OilPrice.com. ———————————– Alternative energy (or renewable energy) is a new manufacturing industry paradigm that is in its infancy. However, the discussion is not new, and it looks as if the United States has positioned itself to be behind history on what can be a very promising industry for a stumbling economy. After the oil shortages in the 70′s, government officials began discussing energy policy as a matter of national security, but this misses the point of a globally competitive economic world. It was too early then to begin thinking that China could out-invest the United States in order to produce an alternative energy manufacturing industry. Yet, now we must come… Continue»
The Renewable Energy Policy Network for the 21st Century has just released their annual Renewables 2011 Global Status Report. I was one of the reviewers of the draft report, and therefore got to read and comment on it prior to publication. The report provides a comprehensive overview of global renewable energy sectors, breaking different categories down by total installed capacity and capacity added in 2010. It also ranks the global leaders for many categories. Renewable energy grew strongly in 2010, as the total global investment in renewable energy reached $211 billion, up 32% from the $160 billion invested in 2009. Globally, the capacity of various renewable energy categories at the end of 2010 was: Solar PV – 40 GW Wind… Continue»
