Does anyone know all the strange facts about wind energy. After looking around, I've learned – Hi AB, there are probably thousands of facts about wind energy. The earliest known windmills to date on the 12 th century AD. Originally they were used to grind grain and pump water. In those days, the person who operated the mill, known as the "Miller" was the most important businessman in town. Typically, a farmer would be all that grew year to which the miller, and barter to get everything to the ground flour in exchange for the miller taking a percentage of the ground product to market himself. A good miller that keep your equipment up and operating a business trust to be known far and wide, and at that time was one of the richest people in the city. Wind power water pump was used sporadically until the Netherlands was resolved, and the rich soil just below the surface of the flood waters each year was drained for cultivation. Over the years, the Dutch have greatly enhanced the science and design of wind turbines, and much of the research being conducted then is still used today. They developed what is still the design of more efficient wind turbine, a single horizontal axis turbine blade. Had a long sheet which extends in a direction from the hub, and a bowling ball-shaped counterweight at the other side. The reason for this was so efficient is that when a piece of windswept, does not stop the wind, using all his energy, changes its direction and slows it down, so a small wave is produced with the wind coming behind her. The following sheet has to cut through this wave, like a motor boat cutting through the wake of another boat, which slows down a bit. This turbine type is really only useful in very low winds, but steady, like the Dutch have most of the year. With the design of modern sheet, the problem of interference after it has reduced but not eliminated. Most turbines today are either 2 blade, a slightly less efficient design, but making better use of materials, and almost as effective or 3 blade, which are designed for higher wind more turbulent, and coniditions gusty. Turbines with more than 3 sheets are rare. They are usually small, and designed for high winds and brutal conditions, such as an ocean liner, or an Arctic weather station. Today wind power is expanding at a dramatic rate. Every 2. 5 years, the world has wind power on twice as much available. This is happening because of the economy generally, not so much for environmental reasons. To be honest, I wish it was for environmental reasons, but most people, and certainly the companies like to talk about problems, but make decisions based on our checkbooks. We live in a house that has been driven by the wind and the sun for about 10 years. Interestingly, we like to know that when we turn on the TV, we are not adding fuel to the fire of coal in local power plant. With both utilities and renewable energy, our house has not been without electricity for one minute over the years, it is hard to put a price on that. Now energy companies and even the neighbors are involved, but usually because it could save money. There are plenty of people around the world who grow their own tomatoes, although it is cheaper and easier for them to buy in the store. They need to know about worms, insects, soil pH, sunlight and irrigation, and spend time weeding the garden. People who grow their own electrons have a similar curse, we have to know how everything works and where everyone goes into our homes. There is a great source for facts and data about wind energy that I think you might find interesting. I will list below. I hope you find this interesting. Who knows, maybe someday you'll have a turbine in your backyard as we do. Be careful AnuuBee, Rudydoo

Small wind turbine blades
February 8th, 2012It is quite clear that this century will be affected by intensification of the struggle for power and this will inevitably push up prices, lead to sporadic shortages and provoke a fight for the stocks of the major economic blocks.Presently the world, more capable and established renewable energy technology appears to be wind power. Wind energy not only be able to have a say in the production of energy sovereignty and climate goals in the future, it could also turn a situation of severe energy supply perspective in the form of benefits commercial, technological research, exports and employment.To meet these challenges, the number and size of wind turbines has increased considerably in recent years, and the material used to manufacture wind turbine blades has improved growth is likely significantly.This to be extended considerably, more than ever, with the creation and operation of a large number of wind turbines in offshore wind farms. It is, in effect, serve as large power plants that generate electricity without stopping for hiccups grid.One there, however. After many years of experhymentation and study, yet no one has been able to design the wind turbine blade perfect for all situations. Depending on its location, options for changing the blades drastically.Wind turbine blades, or in any case propeller are provided so that a rotational force can be transformed into energy forward or vice versa. The ultimate goal of any blade design is to catch as much wind as possible so that the generator is able to achieve and maintain a minimum number of revolutions per minute. The largest area of leaf surface, the more wind you can catch. At the same time, the largest leaf, as the heavier compounds well.Synergy agreement in all varieties of wind turbine blades, and surely can attend to every need of yours.

Wind Energy Careers
February 4th, 2012As "green" devices, solar, wind, ect. . I believe that engineers mechanical and environmental engineering, are good examples, but I often know more runs. Thank you. I was so happy to find this – You mentioned a couple of engineering. Electrical, Civil, Architectural, Construction, Material Resources, Chemistry, Physics, etc., are all involved. But do not forget that the business, legal, medical, and banking could also be related. In short, almost any career could be adapted to focus on alternative energy.
