When I built my electric bicycle back in 2007, I had been waiting for a battery that was less volatile than what had been available. I didn’t want to risk having a fireball under my seat. Tesla traded volatility for power density.
I think electric cars are great for all kinds of reasons, which is why I bought one in 2011. But like any car, they are not created equal, and as marketers begin the process of differentiating them to get us to buy them, that inequality will grow and diversify as it has for conventional cars. And for any fellow electric car enthusiasts out there who think electric cars are going to make a significant dent in carbon emissions in the foreseeable future, read Robert Rapier’s article on that subject. Even a strongly biased study by the UCS shows that electric cars, on average, presently produce about half of the emissions of conventional cars in a cradle-to-grave analysis. Eliminating fossil fuels instead of nuclear from our energy mix will improve that over time. CONTINUE»
I was recently invited to attend the first annual Clean Energy Forum, hosted by Energy Northwest in Richland, Washington, which included a tour of the Columbia Generating station.
We were greeted at the security gate by three polite security guards who inspected the bus and checked our photo IDs against a list. This level of security isn’t unique to nuclear power stations. You would have to go through a similar procedure to take a tour of Hoover dam. We also had to leave our cell phones on the bus (which would also be the case should you ever get the chance to take the highly recommended Boeing, Everett factory tour). CONTINUE»
Melomys Rubicola has been declared extinct. Had it been something like a fuzzy koala or panda instead of a rat, the world might have taken more notice, but maybe not. A Google search on the topic goes over 20 pages deep. This seems to have struck a nerve.
It’s possible that an undiscovered genetically identical population exists somewhere else. It’s not unheard of for a species declared extinct to show up again. But if it has been on that tiny island off the coast of Papua New Guinea long enough for speciation to occur, then it is extinct because to repopulate someplace else a pregnant female would have needed to leave the island and establish itself elsewhere, and that is extremely unlikely.
There have been some dubious claims of extinctions caused by climate change, as one would expect, and I’m sure there will be many more. But little by little, the real extinctions will arrive. CONTINUE»
Contrary to what you read in the lay press, nuclear energy is starting to make major headway around the world with a plethora of new technologies (and attendant potential investment opportunities) on the horizon.

Andrew Revkin posted an interesting article a few weeks back:
Lately, I’ve come to frame the challenge as a question: Can we foster an online (and real-life) culture in which veracity is cool? You’ll see more on this here in the coming months.
As social primates, we are instinctively motivated to seek higher status in our given troop hierarchies. The word cool is sometimes used as a synonym for impressive. Impressive denotes a measure of status. Coolness is any marketer’s primary weapon. I like Andy’s idea of making veracity cool, but I’m skeptical it could ever take hold. How would car marketers ever convince us to buy their cars? Although, certainly, he’s on the right track in that, if you want to change behavior, like getting people to drive electric cars (or Hummers), convincing them it’s cool to drive one will work wonders.

What’s with the green parrots you may be asking? A parrot repeats what it hears without understanding what it’s saying. And by “green” I’m referring to people who, like myself, consider themselves to be environmentalists (whatever exactly that means). To the left of the green parrots is a screenshot of the “shares” from a guest post on the Clean Technica website, which has at least 99 parrots sitting on their wire.
It all started when an apparent shale gas enthusiast (Nick Grealy) wrote a 1,100 word article at his blog about the use of shale gas in France which contained the following rather cryptic throwaway sentence:
French nuclear exports help Germany, the UK, Italy and Spain accelerate their renewable uptake.

Although quite upbeat about solar PV (and I’m also a big fan of solar PV), this article generated almost 300 comments because it was also frank about the limits of solar PV, and wind, and to make matters worse, he concluded the article with the following statement:
My view is that only two forms of energy — solar and nuclear power — can plausibly supply tens of terawatts without a huge environmental impact.
Nicholas Kristof wrote an opinion piece for the New York Times a few weeks ago titled: “Terrorists, bathtubs, and snakes.“
It was about how our evolved abilities to assess risk (which worked great when we were hunter-gatherers) can fail us pretty miserably in the modern industrial world–a point that has been made over and over again by lesser known writers over the last decade about the safety of nuclear powerplants.
In short, our brains are perfectly evolved for the Pleistocene, but are not as well suited for the risks we face today. If only climate change caused sharp increases in snake populations, then we’d be on top of the problem!
Yet even if our brains sometimes mislead us, they also crown us with the capacity to recognize our flaws and rectify mistakes. So maybe we can adjust for our weaknesses in risk assessment — so that we confront the possible destruction of our planet as if it were every bit as ominous and urgent a threat as, say, a passing garter snake.
I found this study on Nature Energy, which I subscribe to: Moving beyond alternative fuel hype to decarbonize transportation.
Although I disagree with the study’s main conclusion, the above chart they put together (which I have modified) was of interest to me because it suggests that things are finally starting to happen when it comes to electrification of transportation. CONTINUE»
The front page of last Sunday’s edition of the Seattle Times had an article titled Elwha: Roaring Back to Life. It’s an update on the many positive impacts to the river ecosystem after removal of the Glines Canyon and Elwha hydroelectric dams, writes Russ Finley.
