Hydrogen

Hydrogen is the fuel of the future but only after controlled fusion is developed. To use hydrogen today is a waste of energy since the electrolysis of water is too expensive and uses far more energy than it saves. In the interim the best way to tackle the problems of climate change is to use natural gas for power plants and transportation. The average person is not concerned about climate change at least based on their life style. For most people the concern about climate change is political not environmental.
