Well, gee whiz, the stimulus is a total fail in another area:  Electric Cars Will Not Decrease Greenhouse Gas Emissions, Says Federal Study

The stimulus law enacted in February promoted the purchase of plug-in electric cars by the federal government and the broader market, but a Government Accountability Office (GAO) report released this month says that the use of plug-in electric vehicles will not by itself decrease greenhouse gas emissions.

To do that, the report argues, the United States would have to switch from coal-burning plants to lower-emission sources to generate electricity such as nuclear power.

“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?”
Mark Gaffigan, co-author of the GAO report and a specialist in energy issues told CNSNews.com.

The report found that the adoption of plug-in cars could result in benefits, including reduced petroleum consumption and dependency.

But it concedes that in regions of the country heavily reliant on coal for power generation, electric plug-in vehicles will not result in a decrease in green house gas emissions.

“Reduction in CO2 emissions depend on generating electricity used to charge the vehicles from lower-emission sources of energy,” GAO reported.

“For plug-ins to reach their full potential, electricity would need to be generated from lower-emission fuels such as nuclear and renewable energy rather than the fossil fuels–coal and natural gas–used most often to generate electricity today.”

So the anticipated results will only occur after a major overhaul of electricity production in the country.  Good going, Congress, signing bills without reading them and considering the consequences.
