Electric cars are greener in France than in China

Countries that use cleaner sources of energy can help maximize the benefits of an electrically charged car. Norway, for example, is an almost completely hydro-powered nation while France relies heavily on nuclear and renewable energy. China on the other hand is still mostly coal-powered. That means an electric car in China is only 15% cleaner than a fossil fuel car, compared to a worldwide average of 40%, according to a Bloomberg News analysis.
