According to the laws of physics it would be more efficient to have our energy based upon electricity instead of hydrogen Hydrogen as an energy carrier would be less efficient than electricity.
In a sustainable energy future, electricity will become the prime energy carrier. We now have to focus our research on electricity storage, electric cars and the modernization of the existing electricity infrastructure.

The focus should be on modernizing our energy sources, which I have pointed out should have as its first priority the reduction in the usage and eventual elimination of coal power.
