My personal issue with EVs is that most people who like them don't really understand or refuse to acknowledge that their cars also run on fossil fuels, they're just not doing the combustion under the hood.
The three major fossil fuels—petroleum, natural gas, and coal—accounted for most of the nation's energy production in 2015:
Natural gas—32%
Petroleum (crude oil and natural gas plant liquids)—28%
Coal—21%
Renewable energy—11%
Nuclear electric power—9%

Since EVs are also much heavier in general (Tesla P85D is ~4936lb vs a Corvette at ~3347lb or a Civic at ~2738lb), even though they are pretty efficient, they're still pretty close (when I ran the numbers before, they were higher) in greenhouse gas emissions once you factor in how much energy it takes to drive one vs an ICE vehicle. Batteries are also pretty nasty to dispose of and have a comparatively short lifetime -- a well-maintained car from the 90s is still very much drivable today (and cars without batteries can be maintained almost indefinitely), while battery packs aren't very useful past 7-10 years.
In that same vein, rare earth minerals are required in much larger quantities for EVs due to the batteries and the motors. Many countries mining and processing those don't care much about the environment, so they're mined and processed in environmentally-irresponsible ways, and we're now massively increasing demand for them. This is from 2010: http://www.cbsnews.com/news/forget-lithium-its-rare-earth-mi...
Because they're sold as "green" and "zero emissions", and due to the various government tax breaks (which even applied to >$100k Teslas and >$1m Porsche 918s), single-driver carpool lane privileges in California (significant because about 50% of EVs sold in the US are in CA), priority parking spots, free (employer-subsidized) charging at many workplaces, EVs are ever more popular despite them being about even from what I can tell for the environment when you look at the total lifecycle vs normal cars. This bothers me. Many EV drivers do not seem to understand the impact their vehicles have, seemingly because it says "zer0 emissions" on the license plate frame.
