Windmills Electricity: How Does It Work Anyway?

 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.
