Why electric cars are only as clean as their power supply

Electric cars have never been closer to the mainstream, the market pushed ahead by California subsidies for electric car buyers, and a wide array of new models from established car firms such as Toyota and Chevy. Tesla’s focus on luxury, high-performance vehicles has also broadened their appeal; electric cars are no longer purely an environmental statement, but a tech status symbol too.

Yet the “zero emissions” claim grates on some experts, who have continued to argue over whether electric cars are really more environmentally friendly than gas guzzlers, once the manufacturing process for the vehicles and their batteries are taken into account.

Electric cars rely on regular charging from the local electricity network. The power plants providing that energy aren’t emission-free; even in California, 60% of electricity came from burning fossil fuels in 2015, while solar and wind together made up less than 14%.

Too true.. in Western Canada we are pretty good as we use hydro power. I would feel better though if tidal n wind power were used more as hydro power isn't perfect
