Turkey Point Power Station and its Ecosystem

I recently took a trip to Florida, which is home to both the American alligator and the American crocodile.  Thanks to effective laws and effective enforcement of those laws, the alligator population has rebounded into the millions. They’re all over the place. In comparison, the crocodile population has rebounded from an estimated low of about two or three hundred to about 1,500. Crocodiles were never as common in North America as the cold-adapted alligator. The opposite is true in South America where there are no alligators. Click here to see a video I took several years ago of crocodiles in Costa Rica.

Google Engineers Conclude that Renewable Energy Will Not Result in Significant Emissions Reductions


Graphic from Stockholm Resilience Centre Study Combined with Pie Chart of WWF Study

Back in 2007, Google assembled a team of engineers to investigate the feasibility of replacing fossil fuels with renewable energy. The effort ended in 2011 with the conclusion that it can’t be done with existing technology. Two of the engineers on that team wrote about their efforts in Spectrum Some excerpts from that article:

Google’s boldest energy move was an effort known as RE<C [Renewables less than Coal], which aimed to develop renewable energy sources that would generate electricity more cheaply than coal-fired power plants do. The company announced that Google would help promising technologies mature by investing in start-ups and conducting its own internal R&D.

At the start of  RE<C, we had shared the attitude of many stalwart environmentalists: We felt that with steady improvements to today’s renewable energy technologies, our society could stave off catastrophic climate change. We now know that to be a false hope—but that doesn’t mean the planet is doomed.

As we reflected on the project, we came to the conclusion that even if Google and others had led the way toward a wholesale adoption of renewable energy, that switch would not have resulted in significant reductions of carbon dioxide emissions. Trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work; we need a fundamentally different approach.

So our best-case scenario, which was based on our most optimistic forecasts for renewable energy, would still result in severe climate change, with all its dire consequences: shifting climatic zones, freshwater shortages, eroding coasts, and ocean acidification, among others. Our reckoning showed that reversing the trend would require both radical technological advances in cheap zero-carbon energy, as well as a method of extracting CO2 from the atmosphere and sequestering the carbon.

We’re glad that Google tried something ambitious with the RE<C initiative, and we’re proud to have been part of the project. But with 20/20 hindsight, we see that it didn’t go far enough, and that truly disruptive technologies are what our planet needs. To reverse climate change, our society requires something beyond today’s renewable energy technologies. Fortunately, new discoveries are changing the way we think about physics, nanotechnology, and biology all the time. While humanity is currently on a trajectory to severe climate change, this disaster can be averted if researchers aim for goals that seem nearly impossible.

The key is that as yet invented sources have to be cheaper than fossil fuels. The problem is that existing scalable low carbon energy sources (nuclear and renewables) are all more expensive than fossil fuels, which I’ve been pointing out for years. They make a stab at explaining why wind and solar are more expensive but trust me, their explanation will largely fall on deaf ears when presented to renewable energy enthusiasts who either don’t want to hear it or are incapable of comprehending it. They argue that subsidies for renewables and nuclear to compete with fossil fuels are essentially a financial penalty to fossil fuels which simply shift their use to another part of the planet (export of oil, gas, and coal, along with manufacturing jobs).

New IEA Study: Least Cost Scenario has Nuclear as the World’s Largest Source of Electricity by 2050

An article in Grist about the same study had a different headline: “How solar can become the world’s largest source of electricity.” From the study:

The hi-Ren requires cumulative investments for power generation of USD 4.5 trillion more than in the 2DS, including notably PV but also wind power and STE (Solar Thermal Energy).

The study also notes that, in theory and given enough time, power systems that don’t burn fossil fuels should eventually pay for themselves with fuel cost savings (which is also a trait of nuclear). See Figure 5 below.

Nuclear Energy Deniers

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 Base Load Free Power System

Below I Fisk an article titled Why Germany is phasing out nuclear power by David Roberts.

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.

Energy Sources Versus Nature

Welcome to the sixth extinction event.

This is a portrait of an axolotl. My youngest daughter has two of them. They are almost extinct in the wild. However, because they breed well in captivity and because they are valuable for research (they can regenerate entire lost appendages), there is a large captive population. Coincidentally, she also has a pet New Caledonia crested gecko, also on the verge of extinction in the wild, which also breeds well in captivity, and also has a large captive population.

Electrifying the USPS

I usually scan the energy headlines each morning, but had somehow missed the stories on the recently introduced bills to electrify the U.S. Postal Service fleet:U.S. Postal Service to test a repurposed electric vehicle fleet Rep. Gerald E. Connolly (D-Va.) introduced a bill Friday that would pay for 109,500 electric vehicles, though the cost of that program isn’t known yet. “This, to me, would be a very productive thing and . . . likely to produce jobs and revitalize an industry,” Connolly said. In December, Rep. José E. Serrano (D-N.Y.) announced an “e-Drive” bill that would give $2 billion to the Energy Department and Postal Service to convert 20,000 mail trucks into electric vehicles. I have always liked the idea… Continue»

Book Review – Power of the People

I will finish up my long-promised concluding post in the recent series on ethanol and oil imports. I have been traveling for ten days, and inadvertently left all of my graphics for that post on another computer. I am back home now, and will try to tidy it up and post it in the next few days. On the long plane ride back to Hawaii, I read Power of the People: America’s New Electricity Choices. I picked this book up at the 2009 Solar Tour – Pikes Peak Region, which I visited on my trip to Colorado. My new job has me getting more involved in the electricity sector, and I thought this would be a book that would help… Continue»

Vinod Khosla at Milken Institute: Part III

This will be the conclusion of Vinod Khosla’s (VK) recent lengthy interview at the Milken Institute 2009 Global Conference. The interview was conducted by Elizabeth Corcoran (EC) of Forbes and can be viewed here. In Part I, VK discussed the role of government money, capital intensity of renewable projects, and some of his solar investments. In Part II, VK discussed butanol, cellulosic ethanol, nuclear power, and cap and trade. Here in Part III, VK discusses his beef with electric cars, has lots to say about Black Swans, discusses his problems with nuclear in more detail, talks about green jobs, sugarcane ethanol, and weighs in on indirect land use issues for biofuels. EC (39:00): Let’s get to those electric cars. You… Continue»
