The New York Times on how electrical cars are making money Matthew L. Wald reports on how a University of Delaware professor is testing the use of electrical cars in regulating the electricity grid, thus turning a profit for their owners: "A line of Mini Coopers, each attached to the regional power grid by a thick cable plugged in where a gasoline filler pipe used to be, no longer just draws energy. The power now flows two ways between the cars and the electric grid, as the cars inject and suck power in tiny jolts, and get paid for it. ... The market that Professor Kempton is tapping into, known as frequency regulation, has become increasingly important as the mix of generators on the grid has changed. If electric cars become more popular, proponents say that a network of thousands of plug-in cars could help stabilize the grid."
Grist on the fear of carbon trading After discussing recent questions facing the European Union's carbon-emissions trading scheme — prices for carbon credits are dropping — David Roberts argues that prices aren't exactly the point of carbon-trading programs. "The idiotic and ill-informed debate over cap-and-trade in the U.S. in 2009-2010 distorted how many Americans see carbon trading," he writes. "And as many recent media reports illustrate, people everywhere still have trouble grasping how such programs are supposed to work. But carbon markets remain a powerful tool, popular among policymakers, and they are slowly creeping their way across the globe. We are, admittedly, a long way off from a global carbon market, but that once-fanciful goal is at least visible on the horizon. So let’s chill out a little."
