Clean Electric Cars Need Clean Power Sources

South Africa's heavy reliance on coal to generate electric power, like in China, deflates the environmental value of electric cars.

Cape Town - Wits researchers have reported that electric cars will not reduce greenhouse gas emissions blamed for global warming.

"We found that, as the bulk of South Africa's electricity is generated from relatively low-quality coal and the advanced exhaust clean up technologies are not implemented in the current coal-fired power plants, the use of electric vehicles in South Africa would not help to cut greenhouse gas emissions now (2010) or in the future, " the researchers reported.

Electric vehicles have been suggested as a way to reduce the carbon emissions in urban centres, but researchers Diane Hildebrandt, David Glasser and Xinying Liu said that the generation of electricity should be taken into account.
