Zero emissions sounds wonderful but it's not entirely true. While electric cars typically emit less CO₂, over its lifetime a Tesla S will emit about 13 tonnes of CO₂.  The production of its batteries alone will emit 14 tonnes. <ref>[http://www.telegraph.co.uk/opinion/2016/04/06/dont-be-fooled---elon-musks-electric-cars-arent-about-to-save-th/ Don't be fooled - Elon Musk's electric cars aren't about to save the planet, The Telegraphe, April 6, 2016]</ref>

Coal power still accounts for 39% of America's electricity power. This means that electric vehicles will still be responsible for producing CO₂. A North Carolina State University study showed that a nation full of electric cars powered will make no ecological difference. <ref>[http://www.investors.com/politics/editorials/tesla-the-coal-powered-car-wont-be-saving-the-world/ Tesla, The Coal-Powered Car, Won’t Be Saving The World, Investors.com, April 4, 2016]</ref> This is due in part to its production costs, rare metal mining.

The disposal of batteries is also a concern. Dead ones can't be tossed in a landfill and few companies will recycle lithium batteries and electric cars have giant batteries.
