It may be possible for everyone to have their own power plant with energy supplied by their own fuel cell. With the diminishing supply of fossil fuels comes the need for alternative sources of energy. Sources such as solar energy and nuclear energy are still being developed. As with all technology, it will take time to bring the costs down and efficiency up. In the mean time, we need to try and fine a way to use our existing supplies more efficiently.
Fuel cells are probably the best way to do it.
