In addition to the established energy sources such as gas, coal, oil and nuclear, there are a number of other sources that we ought to consider. Two of these are hydro-electric and tidal power. These two sources are similar in that they are both renewable. However, hydro-electric power is more widely used than tidal.

In its search for alternatives to fossil-fuel energy sources, science is looking back in history at the windmill. Small windmills once were seen everywhere in rural America, but most were abandoned with the emergence of rural electrification programs in the 1930’s. Now energy shortages and rising petroleum prices have brought renewed interest in putting the wind to work.
