Few words on the wind The sun heats unevenly in different parts of Earth. Heat energy that reaches the poles lower than that which comes to the equator. The result is the creation of differences in air pressure and movement - wind. Heat energy absorption rate of water absorption of slightly slower than the heat created by land and therefore temperature differences between air over the sea and the air above the land. The result is familiar in strong winds than the coastline. Stronger winds also great plains and in mountainous regions due to few factors Regents air traffic in these areas. Wind energy is clean energy could be exploited without causing environmental damage. Man has no control over the wind and tropical storms still cause victims and destruction, but the early twentieth century - 21 starts massive use this energy to generate electricity. The Danish example Denmark has a rare natural resource - a very long beach. Denmark's coastline is about 7,000 miles as a result of the many islands and numerous bays. Location between the northern Baltic Sea bathing perhaps less attractive due to sea temperature, but it promises strong winds and stability in most of the year as a resource for nature to be derived from electricity. Today about 20% from the supplier of electricity in Denmark is produced by wind turbines, making it the market leader. Wind turbines The technology of generating electricity by wind turbines has been around for decades. The main problem that prevented widespread industrial production was the lack of economic viability. Until a few years ago, construction was very expensive and the resulting revenue stream from the sale of electricity not covered in the current financing costs. Technological improvements made in the last decade, which increased the most of the turbines and improved power storage technology, changed the balance sheet. Now, in many places in the world, generating electricity through wind turbines is an economic and profitable. Significant technological improvements included train blades from composite materials, mainly carbon fiber, soft blades formed and more durable than metal blades. Low weight of the blades allows better utilization of wind energy. One disadvantage of using wind power generation is the dependence of the strength of the wind power provider, thus created a greater need for hoarding power (as opposed to the power station that uses combustible materials far that production in uniform). Improving the means for collecting and routing reduced the power of this drawback. Another significant factor in improving the profitability of power generation by wind turbines is rising oil prices and the rise of other combustible materials prices rise in the production of electricity competing technologies. Also growing awareness of the ecological advantage of power generation using non-polluting material effect on the expansion construction of wind turbines. In many countries electricity producers using environmentally friendly technologies receive significant tax breaks. With a rapidly growing economic viability of production capacity. By 1997 the global electricity production capacity by wind turbines was 7,475 megawatt -. In late 2006 the electricity through wind turbines is about 73,900 megawatt - almost 10 times less than a decade. It is important to note that the data shown are the optimal production capacity in the wind, because that production depends on the mood. Actual production stands at about 35% of capacity is reported. The rapid expansion of power generation by wind turbines has occurred mainly in Europe, where he became a two-thirds of the electricity produced by this method. In Germany alone, in late 2006, has a production capacity of 22,600 megawatt - which is about 7% of the country's electricity use. Spain's production capacity stands at 11,600 megawatt - and he is 9% of electricity consumption in the country. Substantial expansion is expected in the U.S., Canada, China, India and Brazil. Estimated production of electricity using wind turbines will double itself within four years. From shore to sea One of the major limitations is the production of wind turbines local limit. Efficient production requires a substantial distance between the turbines, so the area of ??very large turbines. Land in the coastal area is usually very expensive and in addition, it is necessary to stay away from areas of the community to avoid disruption of residents turbine operation noise environment. The solution to these problems is the manufacture turbines in the sea, usually only about ten kilometers from the coast. Production and maintenance of turbines in the sea is more expensive, but greatly increases the potential wind farm areas. Industry Without a lot of noise, within a decade, which makes up one percent of industrial production capacity of electricity worldwide. Industry expected to double itself within four years. Companies comprising the industry are wind turbine manufacturers, turbine operators (usually the largest electricity companies), and component manufacturers to build the turbines, storage and transport of the turbine electrical power grid. Power generation using wind turbines requires a very high financial investment in manufacturing turbines and ongoing investment is very low maintenance. Economic viability is tested by comparing the revenue stream from the sale of electricity with the flow of financing costs of building new turbines.
