Simply put, windmills electricity is that which has been generated by using wind power. Interestingly wind is just another form of solar energy, being created as it is by the uneven heating of the Earth’s atmosphere by the sun. There are other things too that effect the direction and velocity of the wind such as vegetation, landmasses, the terrain and the seas.

 The significant thing is that the wind can be harnessed, and mankind has been doing this for millennia with wind pumps, windmills and sailing ships. Wind pumps were used mainly to pump water from wells and bores. Windmills were used to drive millstones for grinding grain. Confusingly, wind pumps have always been called windmills, and even now we speak of windmills electricity. Recently the nomenclature has largely changed, and electricity windmills are now referred to as wind turbine geneators.

 If we turn on a fan, electric power spins the fan blades and produces a draft of air. With a wind turbine the opposite occurs: the wind spins the ’fan’ blades and generates electricity. To be a little more accurate, the wind spins the blades of the turbine that are attached to a shaft; the shaft is attached at the other end to an electricity generator, and so electricity is generated.

 It should be noted that generators are only efficient in a certain speed range, and it is important when investigating the feasibility of installing a turbine generator that a detailed study is made of the suitability of the site and the prevailing wind conditions.

 Wind turbines are used in domestic situations to either totally replace the power bought from utilities or to supplement it. Commercially manufactured turbines of sufficient output to generate power for domestic situations would cost between $7000 and $20,000 and in many cases this capital cost would not be a viable proposition.

 It should be borne in mind however that thousands of people throughout the United States and Canada particularly and also throughout the remainder of the world are building their own wind turbine generators at a fraction of the cost that would apply to be purchasing a commercial product.

 There are many excellent guides available on the Internet which explain the step-by-step DIY production of wind turbines suitable for domestic purposes. One of the best of these in my view has been produced by Green DIY Energy of Boulder CO. I would definitely recommend that you check it out and you can do so by clicking here.

Traditional sources of energy have two problems. Firstly it is becoming increasingly expensive and that is likely continue into the foreseeable future. Secondly the generation by the utility companies is becoming an increasing risk to the environment, relying as it does on nonrenewable fuel. These considerations are encouraging people to look into alternative means of generating electricity for domestic purposes. One such means is windmills electricity — that is, electricity that has been produced with the use of windmills. Windmills are better known nowadays as wind turbines.

The viability of wind turbines for electricity generation depends on a number of factors. The first is the attitude of local government, for in some cases wind turbines are not allowed to be placed on buildings. Another consideration is wind consistency and strength. Generally speaking the most favorable sites for wind turbines would be in suburban and rural areas that have consistent medium to strong breezes.

Given favorable conditions the next consideration would be cost. Commercially produced wind turbines can cost many thousands of dollars, whereas a home-built turbine can cost as little as a few hundred dollars. The principal consideration is the so-called “payback-period”, which is the time it takes for the savings in the purchase of electricity to equal the cost of installation of a wind turbine. This payback-period can vary between a couple of years and 10 to 15 years depending on those factors of costs of installation and of grid supplied power.

The best source of information for the layman in relation to the building of DIY wind turbines is the many guides that are available on the Internet. I have read as many as I can find, and in my view the best of them is produced by Green DIY Energy of Denver CO. Visit my blog here to get further information about this excellent guide.
