The problem was never could you build a fuel cell that would consume hydrogen, produce electricity, and fit in a car.

"In the United States today, over half the electricity produced comes from coal, and it is far more abundant than petroleum," he said.

In the late 1970's, Federal and state officials predicted that the electricity generated by the plants would produce significant income.

If the price is right, Consolidated Edison will buy the electricity produced, enough power for about 70,000 homes.

The only electricity it uses produces pressurized air for the pipes.

And electricity produced from renewable resources like wind or solar power doesn't produce any emissions at all.

Not until the 1920's, they say, did electricity produce sizable productivity gains.

There are also electric matches, which use electricity and not friction to produce a fire.

It would also employ in the region of 3,500 people and the electricity produced has to potential to be exported to neighbouring countries.

Over the next few years, electricity produced from solar energy will become significantly cheaper.
