Wind Generated Electricity
Electricity from Wind
While electricity could be brought about from energy by the sun, wind energy comes from wind turbines. Wind power is without question a form of solar energy, since wind flow is caused by atmospheric heat from the sun. Power originated by wind comes free, clean and is a wonder part of energy that proves to be an alternative to fossil fuels. Electricity that is started from wind is pollution-free and emits no greenhouse gases.

How Wind Generates Electricity
Wind turbines use propeller blades that travel in the wind to create electricity from wind. As the wind turns the blades, a connected shaft rotates. This shaft that rotates connects to a certain generator which creates electricity by the use of motion.A wind power plant is a series of wind turbines that send electricity through transmission lines. Utility companies then aquire this electricity and give it to homes, businesses and other public buildings such as schools and hospitals.
Since the 1990s, wind power has been the fastest growing source of electricity. The development of most of the wind power comes from Europe, however; The United States still has a very large potential for wind energy. According to the U.S. Department of Energy, the U.S. wind resources could satisfy all electricity requirements for the nation. There are many projects underway to build the infrastructure to support the generation of electricity from wind on a large scale.
Wind power plants cannot be brought up in all areas. The available wind resources in a region must be adequate to make a power plant economically beneficial. The U.S. Department of Energy is administering wind studies to ascertain the best areas to generate electricity from wind.
Wind Turbine Benefits for Homeowners
Homeowners can benefit from wind power by investing in small wind turbine systems. Using a residential turbine to create electricity from wind helps reduce pollution and provides a buffer against energy shortages and energy price inflation. There are several factors to acknowledge before purchasing and installing a residential wind turbine. If your home turns out to be a good candidate for a small-scale wind power system, it can prove to be a cost-effective alternative to electricity bought from your local utility company.

A residential wind power system can be either standalone or attached to the power grid. For a standalone system, a backup power source such as a battery is required for times when wind is not feasible to give electricity. A wind power system that is connected to the power grid is a more practical solution for homeowners who want to benefit from electricity from wind. When wind levels are low, power requirements are met by electricity from the utility company.
Both standalone wind power systems and systems that are connected to the power grid require an average local wind speed of about 10 miles per hour. The U.S. Department of Energy is a good touch point for information about the suitability of different areas in the country for residential wind power systems.
