Wind Turbines are rotating machines that can be used directly for grinding or can be used to generate electricity from the kinetic power of the wind. They provide the clean and renewable energy for us of both home and office. Wind Turbines are a great way to save money and make the environment clean and green.
Basically there are two types of wind generators, those with vertical axis and those with horizontal axis. They can be used to generate electricity both onshore and offshore. Wind Turbines can be combined to form clusters called "wind farms" which are used by large companies to use that power as their backup. Apart from generating electricity they can also be used for grain-grinding, water pumping, charging batteries.
Historically, wind turbines were used for sailing, irrigation and grinding-grains. It was in the early 20th century that it was used for generating power. Today, large wind turbines can be seen in the rural areas or near the sea coast where speed of the wind is generally throughout the day. Device called wind resource assessment is used for estimating the wind speed.
How Can I Install Wind Turbine?
If you care for the environment then you can install wind turbine to power your home. Depending on the location cheap wind turbine are available in the market. However, one need to take many factors into consideration before installing wind turbine at home for eg: Permission to install wind turbine at home, Is the site right, how much power do I need to generate, What equipment do I need, Should I go vertical axis or horizontal axis wind turbine. Wind Turbine installation may be high but in the long run they prove to be much cheaper then the non-renewable fossil fuels.
Future Of Wind Turbine
Over 20,000 mw of wind turbines were installed in 2007 bringing world- wide capacity to 94,112 mw, up 27% from 2006. Cheap, Low efficient wind turbines are available in the market for home use. Five nations – Germany (22,300 mw), the US (16,800 mw), Spain (15,100 mw) India (8000 mw) and China (6,100 mw) account for 80% of the world's installed wind energy capacity. Wind energy continues to be the fastest growing renewable energy source with worldwide wind power installed capacity reaching 94,112 MW in the year 2007. In terms of economic value, the global wind market in 2007 was worth about $36 billion, according to Global Wind Energy Council (GWEC). In capacity addition, the US was in the lead in 2007, followed by China and Spain.
