Strip-mining the Moon: Bad idea, or the worst idea?
As a millennial, I don't share boomers' enthusiasm for the power of science to solve all problems. So when someone says that strip-mining the Moon for rocks rich in helium-3, heating the rocks to harvest the helium, and using that helium for nuclear fusion will solve the world's energy problems, I am inclined to say, “Ha! You power-mad old person, you are living in a science fiction story.” But that, in fact, may be the direction humanity is heading in, moon-wise.

The U.S. gets more power from renewables than from nuclear
A new report from the Energy Information Administration shows that in 2011, renewable power in the U.S. surpassed nuclear for the first time. In the first three months of the year, renewable energy plants -- including geothermal, biomass, wind, water, and solar -- were responsible for about 12 percent of the country's energy production, while nuclear produced only 2 percent.

Fukushima radiation was double previous estimates
Japanese officials have admitted that the meltdown at Fukushima released almost twice as much radiation as they had initially allowed. ("Did we say 370,000 terabecquerels? Oops, that should have been 770,000.") They also said that the meltdown at the plant began five hours after the quake/tsunami double-punch. The plant's operator had said earlier the meltdown […]

Oops: Germany’s nuclear shutdown will cause 100s of million of tons of CO2 emissions
Riding a wave of anti-nuclear sentiment in the wake of Japan's Fukushima disaster, the German government has decided to phase out all nuclear power plants by 2022. That’ll certainly prevent nuclear meltdowns. On the flip side, though, analyses by experts suggest that eliminating those plants will lead to a short-term increase in coal burning, resulting […]

Authorities finally admit that all three reactors at Fukushima melted down
It's official: All of Fukushima's working reactors saw drops in their water levels sufficient to melt their radioactive cores. (Experts have been telling us this for months, but Japanese power company TEPCO wouldn’t acknowledge it.) The only way the self-immolation of the Fukushima Daiichi nuclear power complex could get any worse would be a large […]

Why Germany had to phase out nuclear to build its renewables
Lots of American journalists (including this one!) have gone on and on about renewables and nuclear power in Germany without having a first-hand appreciation of the situation, or even any German language ability. This has led us all to misapprehend some pretty basic facts about why the Germans decided to phase out their existing nuclear […]

Japanese utility baffled that nuclear plant leak couldn’t be plugged with shredded newspaper
Newest terrifying thing at the Fukushima Daiichi plant: A breach in a trench is leaking highly radioactive water into the surrounding ocean. Japanese utility TEPCO tried over the weekend to use concrete to plug the leak. When that failed, they went for the next most logical solution: a mixture of "132 pounds of sawdust, 18 […]
