China’s New Breeder Reactors May Produce More Than Just Watts

Cars That Think

Fast neutrons—that is, ones with 1 megaelectron-volt or more of kinetic energy—split the plutonium atoms, releasing secondary neutrons that are captured by the U-238 and convert some of that U-238 into plutonium. But when bombarded with neutrons, U-238 is readily transformed into an isotope that can: plutonium-239.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. A paper describing the work is published in the ACS journal Environmental Science & Technology. other parts of the US and the world could be different.

Cars That Think

It’s very similar to the infrastructure for electric cars because the idea, ultimately, for electric cars is that you also are revamping your grid to facilitate, whatchamacallit, intermittent renewable energy sources, like wind and solar, because having an electric car that runs off a coal-fired power plant is defeating the purpose, essentially.

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

The team characterized the vehicle emissions across the United States under alternative assumptions for regional electricity emission factors, regional boundaries, and charging schemes. The third highest state subsidies ($5000) are in Georgia, where the comparison of the Leaf and Prius is inconclusive and the Volt is higher emitting.
