Wind energy is generated by windmills, wind turbines or wind generators. Even in the days before industrialization, wind energy was used to pump water. Only recently, it has been used to generate electrical energy. This solution can create a lot of megawatts, making it an excellent renewable energy source.
If used in the home, federal regulations (specifically, the Public Utility Regulatory Policies Act of 1978, or PURPA) require utilities to connect with and purchase power from small (less than 80 MW) wind energy systems. When used to power the home, wind energy makes a promising source for future generations.
Hydro or water energy is a very effective solution, typically generated on a large scale. It can be converted to electricity for use in the home, and other applications. Most recently seen, are the electric cars. Electrical energy production by renewable sources, has been estimated that 90% is from hydro power only.
Water power supplies about 10 percent of the electricity that we use in the United States. In California, for example, about 15% of all the electricity comes from hydroelectric. The only problem with this source, is the effect on the eco-system of the body of water.
As the most available energy source on earth, solar power will contribute to a greener world. It has been said that enough solar energy falls on the surface of the earth every 40 minutes to meet 100% of the entire world’s energy needs for a full year.
You can use solar power in the home for many uses, electricity being the most common. Not only being extremely cost effective and environmentally friendly, it is very low maintenance saving time and effort. A return on investment can be achieved very quickly with a solar power system, making free over time.
