I saw a post on Facebook this week that asked: "And 'wind energy for real I was told that only hype." My thoughts were that if you live in the south-west is expected to witness daily the progress of wind energy. We in the Southeast and Northeast see occasional wind turbines and wind energy is not the future. When we visited the European countries, especially Germany, would have seen a big growth in wind power generation. The course of harvesting energyto move the air can no longer be a fight against windmills thinking. Wind energy will become an important player in the replacement of fossil fuels.
The main reason for the acceptance of wind energy has dropped the cost of electricity. Over the past three decades, the cost of a watt of electricity generated by wind power has fallen, the cost of fossil fuels immediately. In 1970, the turbine blades 32 feet long and wind energy costs $ 2.00 per kilowatt (kW-h). Modern wind turbines with blades130 meters in length have cut costs about 0.05 cents per kWh. with federal subsidies for the construction. In the future, the cost of wind energy will continue to death, while fossil fuels will continue to increase.
As mentioned earlier, the larger blades are more efficient in producing electricity. This is because, more wind is captured by a knife with a wider area. A town of 8,000 required 40 units, its power must be fair, while only requiring a larger model in the mid-1990now produce the same amount of energy.
There are a lot of research under way in the world, has continued to improve the efficiency of wind turbines. On the drawing board turbines with blades almost 300 feet wide. This blade size will lead to less than the cost of wind generation fossil fuels. To use the largest blade, unlimited energy in West Conshohocken, Pennsylvania has had the blade of variable length with a patented blade or knife. ThisInnovation expands or contracts depending on wind conditions. A controller in the base of the tower responds to changes in wind speed, the expansion into the blade in lighter winds and driving winds. Conventional systems must be turned off if the wind is too strong. The blade variable says that 25% is more efficient and, as a prototype in operation since 2002 near Palm Springs, California. For those who are technically curious, there are a lot more research is occurringUniversities and research laboratories on the turbine components, the shapes of leaves and the forecast winds. This research will continue to improve turbine efficiency and further reduce the cost of wind energy.
By almost every measure, the wind power is about to explode. The growth is mainly limited by the availability of facilities, since the higher efficiency turbines have been introduced. The global wind power industry has moved from $ 11800000000 in 2005 increased by $ 17.9 billion2006 Clean edge research projects in the market to triple to $ 60800000000-2016. In the United States in 2006, Wind was the second largest source of new generating capacity out of gas only. More than 2.4 GW of new capacity was installed, increased by 27%, brought the total capacity of wind power generation in the United States to 11.6 GW, enough to power about 2.9 million households, according to the U.S. Energy Association. Combined over the past 20 years, a strong DOE-funded R & D efforts with theirPartnership has lowered the base cost of wind energy by about 80 cents / kWh to only 4 cents / kWh. If the government tax incentives, combined with an incentive of 1.9 cents / kWh for the first 10 years of a project, and other tax considerations, the cost of wind energy are very competitive, and is sometimes lower than the sources conventional generation.
In Canada, wind power generation capacity almost doubled in 2006. Adding new 657 MW for a total of over 1.3 GW.The objective of the Canadian Wind Energy Association to provide for 10,000 MW of wind energy installed in Canada by 2010, should be enough to get 5% of electricity in Canada. Denmark currently produces over 20% of its energy from wind, an attainable goal for Canada. If wind energy were to generate 20% of electricity in Canada, would be the second largest source of electricity behind hydro and anti-nuclear, natural gas and coal.
European countries, the main U.S. and Canada are inThe acceptance of wind energy. The total capacity of new wind turbines on line throughout the European Union has brought last year was 8554 MW, an increase of 935 MW for a value of 2006. Total capacity of wind power will be installed by the end of 2007 to avoid about 90 million tons of CO2 per year and 119 terawatt-hours in an average wind year, equal to 3.7% of EU electricity demand . In 2000, less than 0.9% of EU electricity consumption at the expense of wind energy. The European countries have decided that wind power20% of the production capacity of 2020.
The Asian countries are rapidly adopting wind power. India added 1.8 GW of wind power in 2006. Suzlon Energy, Pune, is the world's most profitable manufacturer of wind turbines. Meanwhile, the plans of China had an installed capacity of 2.6 GW in 2006, installed over 30 GW, enough to average 30 million Chinese households in 2020.
The acceptance of the common obstacles of wind energy are:
Not in my backyard
People knownot like the sight or sound of the wind turbines in their backyards. This is particularly for the sea. This is a big obstacle to overcome. It may be that the production of wind energy platform further from the transmission of energy without its problems go.
It kills birds and bats
This concern is less and less every day. Studies to date have shown that the position of the wind turbine (s) is the main problem. The turbines migration paths cause the most problems. Sothe location of future turbines recognizes the concern for birds and bats. Different colors for the blades and the warning sounds are analyzed in order to eliminate this danger.
Hurts Tourism
There are small studies on this opinion, but there are no statistical conclusions. When the turbines put out the eyes of everyone to be happy, but we can not always have that luxury ...
