Nothing "fixes the problem". That is a non-argument. But electric cars are a huge step in the right direction and important in enabling the transition to renewables. Be it only by being a storage by nature.

This is the whole problem. Its only a small step forward but people think it'll make a huge difference. Ideally people would move to a small urban apartment and walk or take public transport. EVs let people continue to drive and think they're OK.
