...Therefore, it is no great surprise that power generators routinely store fly ash in unsafe conditions—and not just in Kingston. A 2007 EPA report concluded that fly ash had contaminated surface and ground water at 67 sites. Last month, the Department of the Interior found that 27 percent of American freshwater fish contained unsafe levels of mercury; fly-ash pollution is a likely contributing factor. The coal industry’s failure to safely dispose of fly ash has put hundreds of American towns in harm’s way. A rapid and meaningful response from...
...EPA has already taken steps in the right direction. In March, the agency’s director, Lisa Jackson, announced a plan to inspect disposal sites, order cleanups and repairs, and develop safety regulations to be announced by December. Furthermore, Representative Nick Rahall has proposed legislation that would federally mandate engineering standards for fly-ash impoundments. The TVA is now preparing to convert its coal waste disposal from slurry form to dry storage, which is much less likely to leach into soil and cause toxic spills...
...With the Volt, GM is among the first to make some marketing hay from the unreleased EPA revisions, which evidently take into account onboard gasoline generators like the Volt's. Specifically, GM bases its 230-m.p.g. boast on a blend of the Volt's electric-only mode - which has a 40-mile-range limit - and charge-sustaining mode, with its 1.4-L electric generator running. (The generator is a small gas-powered engine that keeps the batteries charged while the car is being driven, hence the "extended range...
...EPA's new EREV testing process, like the one that California's Air Resources Board (ARB) uses, may not actually measure gasoline usage at all but rather kilowatt hours per 100 miles, or kWh/100m. That figure is converted into miles per gallon, which effectively makes miles per gallon irrelevant...
...says the EPA will weight plug-in electric vehicles as traveling more city miles than highway miles on only electricity, presumably figuring that people buy electric cars primarily for local driving. GM expects the Volt to consume 25 kilowatt hours per 100 miles of city driving. At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for enough electricity to travel 100 miles, or less than 3 cents per mile. (Conversely, a gasoline-powered car that gets 20 m.p.g., for which the driver pays $3 per gallon...
