I think this really points out just how big of a problem energy sources are.

We are having major problems with fossil fuels and the impact the byproducts of getting energy that way. Batteries, which are very important to many forms of electric cars, are very difficult to scale up without being dangerous in a small percentage of cases.

Whomever finds the silver bullet of energy will become the next richest group in the world (and incidently save the planet from boiling).
