Electricity produced by wind turbines is green power in that it causes no environmental pollution. No greenhouse gases which contribute to climate change are produced either. Wind power generation can be on a large scale,which is the case with most commercial projects,or on a small scale as with home owner turbines. Wind is the cheapest form of renewable energy without a doubt. Solar energy is also clean,green,power but is more expensive and limited in output. Solar panels are presently expensive in relation to the power they can produce. Nuclear energy supplies a lot of the power requirements in some countries,notably in Europe. There is however much public opposition to building new nuclear power plants. In the USA natural gas is the biggest form of new energy production. Wind power is the next in line. In 2008 wind turbines will produce about 1% of the United States power needs. Around 30% of new energy production installed in 2007 was wind power. Many consumers now realise that green energy must be our highest priority in future,if we are to minimise climate change and it effects. The trend to building fossil fuel powered generating stations must be reversed. Home owners and farmers can help with the transition to clean power by installing small wind turbines to supply all or part of their electricity needs. These turbines can be purchased from a number of manufacturers and can be installed as a rooftop wind turbine or on a small free standing tower. Commercial wind turbines are quite expensive in relation to power output. A better solution for many is to build their own low cost wind turbine. A good turbine can be built from auto parts and a few odds and ends at very low cost. Plans and instructions are available for this project. Any excess power production can be sold to the power utility in many areas thus reducing the cost even further. Power can also be stored in batteries for use when the wind is too light. Even a light breeze will however produce power. The average home owner can easily build a small wind turbine or several of them to supply part or all of the power required. All that is needed is simple tools and some auto parts and wood. Several can be built for the cost of one commercial wind turbine. Not a bad business also for anyone who wants to make them for resale. The demand for a low cost turbine is there and can only grow in years ahead. Why not build your own wind power turbine now and produce your own free green electricity. You will be doing mother earth a favor by reducing atmospheric pollution. This is an idea whose time has come.
