Oil, gas and coal, which are the world’s supply of fossil fuels, will sooner or later, run out. In preparation for this, considerable work is already being done to find Energy Alternatives. Nuclear power is just one of the considerations. Another natural and perhaps most obvious source of energy is the sun. Here, we give thought to the many other alternative energy sources.
