Woot! This is good news for all of us, from the NRDC’s report on Toxic Power: The electric power sector is the largest industrial source of toxic air pollution in the United States. Thanks to new standards by the Environmental Protection Agency (EPA), toxic pollution from power plants will decline dramatically over the next several …

Andrew Revkin from Dot Earth explores whether China will soon switch to natural gas and the answer appears to be, yes. Reports showed that China — which was once considered gas poor — now has estimated volumes greater than those of the United States (which are, as you know, enormous). With the two greatest economies on Earth …

We have an aging fleet of power plants: 51% of all generating capacity is 30+ years old. 73% of all coal plants are 30+ years old 24 out of 25 oldest plants (60+ years) are hydropower Nearly all nuclear plants are 20+ years old Here is a graphic from EIA with more detail. The pie …
From the AWEA press release: The 50 gigawatts (GW) online today means that U.S. wind turbines now power the equivalent of nearly 13 million American homes, or as many as in Nevada, Colorado, Wisconsin, Virginia, Alabama, and Connecticut combined. In addition, 50 gigawatts (GW) of wind power capacity: Represents the generating power of 44 coal-fired …

The other day I heard in passing, “wind is now cheaper than coal.” If true, this symbolizes the holy grail of renewable energy. It would mean that a turning point for not only cleaner energy, but global warming, climate change, pollution, foreign oil dependence, and more. To fact check this, I pulled up the top …

Last month, Michael Noble of Fresh Energy put up a fascinating list of projections made by energy experts around 2000 or so. Suffice to say, the projections did not fare well. They were badly wrong… What should we take from this? The projections weren’t just off, they were way off. You can find similarly poor projections from the ’70s that …

The final review of the radiation leak at the San Onofre Nuclear Generating Stations (SONGS) has been completed by the Nuclear Regulatory Commission (NRC). Among its findings are that Southern California Edison (SCE) responded appropriately to the issue, while Mitsubishi Heavy Industries, a company based in Japan, is to blame. They found that Mitsubishi’s “faulty …
Here are a few of our favorite alternative ice cream-making apparatuses, ranging from low — to even lower — tech: #1 A plastic Ziploc bag inside a larger bag filled with ice and rock salt applies the standard equation — freezing temperature plus agitation for 5 minutes — and wins the prize for the most elegantly …
That coffee you’re drinking while gazing at your iPad? It cost more than all the electricity needed to run those games, emails, videos and news stories for a year. The annual cost to charge an iPad is just $1.36, according to the Electric Power Research Institute, a non-profit research and development group funded by electric …

“In the past year, coal plants have been facing a perfect storm of falling natural gas prices, a continued trend of high coal prices and weak demand for electricity,” Susan Tierney wrote in the report. Tierney wrote that those factors have combined to make coal a less desirable fuel source. Coal-generated electricity has been waning …
