Most power plants in the United States and all over world are using fossil fuels to operate and generate electricity. They have been used as an energy source as long as man has learned to generate power. These traditional fuel sources have been around for ages and when man started using this energy sources no one though about the consequences. Fossil fuels will eventually run out and there will be a shortage of it in near future. This shortage in will have its affect on our daily live and various industries. Today we see some of these affects already, prizes are raising and electricity is becoming more expensive. Although these fuels are more scares, the need will still be here and will not decrease in near future. To solve this shortage we will need to look for other possibilities for our energy demand.

Fortunately, alternative energy sources are growing in interest. For instance, locations with high water falls are experimenting on building a hydro-electric power plant, which turns out to be successful. Other locations with high wind speed make use of a power wind mills that can convert wind power into electricity. Also thermal and tidal powers are good alternatives.

Solar energy is also one of the energy sources that is gaining in interest. This form of energy has steadily been growing. Today it is widely used in the US and other parts of the world and the advantages are numerous. Our solar energy source, the sun, its life span is estimated to be another 4.5 billion years. It is fair to say that this energy source is almost endless.
