moving away from fossil fuels is a good idea, because they are not the future, and they are not unlimited. At some point, we face the simple fact that oil will run out sooner than the sun or the wind.
So, we need to continue to invest in research of products that are comparable and that don't rely on them. Even if currently creating electrical cars involves burning fossil fuels or mining of some metals, we don't just throw our hands up and say....well we give up.
