Yes, electric cars can help to reduce global warming. By running on electricity instead of gasoline, they eliminate tailpipe emissions, including nasty greenhouse gases that contribute to climate change. If electric car batteries are charged with renewable energy like wind or solar, the benefits are even greater, with their total greenhouse gas emissions hugely undercutting those of vehicles with internal combustion engines. So if people try to give you 10 reasons why electric cars are bad, remember, there are many reasons why they are good for the environment.
