* We obtain most of our energy in the United States today from petroleum, coal, and natural gas. We expend this energy primarily on electrical generation and on transportation.

(2)Second, if the greenhouse effect is really pushing temperatures up to damaging levels, the world--and most particularly the United States--may have to limit the burning of fossil fuel.


It has long been known that hydrogen could be an almost perfect energy source. Nonpolluting and theoretically obtainable from ordinary water, hydrogen burns more efficiently than hydrocarbon fuels, and hydrogen combustion yields no toxic substances, only heat and water. With all of these possible pluses, why are we not planning a hydrogen future? There are, it seems, tough technical and cost problems to solve first. What are the major disadvantages of hydrogen as an alternative energy source today? Cost of production is the major problem, and until some technical breakthroughs occur, costs will remain the limiting factor for some time to come.
