LOS ANGELES (Reuters) – The Prius hybrid automobile is popular for its fuel efficiency, but its electric motor and battery guzzle rare earth metals, a little-known class of elements found in a wide range of gadgets and consumer goods. That makes Toyota's market-leading gasoline-electric hybrid car and other similar vehicles vulnerable to a supply crunch predicted by experts as China, the world's dominant rare earths producer, limits exports while global demand swells. Worldwide demand for rare earths, covering 15 entries on the periodic table of elements, is expected to exceed supply by some 40,000 tonnes annually in several years unless...

General Motors announced with great fanfare last week that its new Chevy Volt will get 230 miles per gallon. Not to be outdone, Nissan quickly announced that its new electric car, the Leaf, will get 367 mpg. If you believe that, we have a couple of auto companies in Detroit to sell you. The car companies are using the Environmental Protection Agency's draft methodology to figure out their fantastical mileage numbers. The hitch is that mpg estimates measure the efficiency of engines that run on petroleum. In an era of electric cars -- when vehicles supposedly won't be propelled by...

The push for conversion to plug-in electric cars will do nothing to stop carbon emissions, a report by the GAO warns, throwing cold water on a push by Democrats to get more plug-ins on the road. In fact, the problem could be made worse as demand goes up at coal-fired electrical plants. Plus, the need for batteries may just have the US changing the dictators to which we’re chained, as IBD reports...

Conservation: The Chevy Volt is said to be able to get 230 miles per gallon. That's if it's continually plugged into a fragile and overburdened power grid. Where will you be when the lights go out? Since most U.S. electricity generation is not carbon-free, the Congressional Research Service agrees. The "widespread adoption of plug-in hybrid vehicles through 2030 may have only a small effect on, and might actually increase, carbon emissions," it observes. "If you are using coal-fired power plants and half the country's electricity comes from coal powered plants, are you just trading one greenhouse gas emitter for another?"...

Alternative Energy: A government report says reliance on electric cars will do little to reduce greenhouse gas emissions and may merely shift our dependence on foreign sources from one set of dictators to another..."If you are using coal-fired power plants, and half the country's electricity comes from coal-powered plants, are you just trading one greenhouse gas emitter for another?" asks Mark Gaffigan, co-author of the GAO report. The report itself notes: "Reductions in CO2 emissions depend on generating electricity used to charge the vehicles from lower-emission sources of energy."
