Energy crisis is not a myth it has become a reality.
Recent data showt that within a decade or two mankind will have expended more than half of Earth's oil. So the mankind can meet major crises connected to oil: global warming, the mounting debt of poorer nations that control no reserves, and the Middle East conflict.
The only alternative to oil for today is hydrogen.
This idea has already found support from the US government and leading carmakers. The federal government recently announced an agreement with major automakers to speed the development of fuel-cell vehicles, which would turn hydrogen into electricity.
Most commercial hydrogen is currently extracted from natural gas. And in the future, renewable resources such as wind, hydro, and geothermal energy will be used to separate hydrogen from water.
