Takes a lot of lost heat just to generate that electricity....

Power plants need fuel to burn as well that need to be mined and depending on the fuel refined. And power plants are not much more efficiant.
Typical thermal efficiency for utility-scale electrical generators is around 33% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.) source
Modern gasoline engines have a maximum thermal efficiency of about 25% to 50% when used to power a car. source
Over all electric vehicles just shift the fossil fuel consumption from one place to another.
