Wind energy – power derived from wind: used to generate electricity or mechanical power – http://dictionary.reference.com/browse/wind+energy
Wind energy is renewable, widely distributed, cheap and doesn’t have toxic gas emissions. There is also a possibility of it helping to diminish the greenhouse effect. It is reliable, so as long as the sun exists, there will be wind. Wind energy is available everywhere, so the dependence for energy from other countries could be depleted. It only takes one mega-watt of wind energy to produce enough electricity for 350 households. The AWEA wants Congress to pass national mandates for generating renewable power.
The first use of wind energy was the use of windmills that were used for grinding, pumping and hammering farm needs. Wind energy can be converted into forms such as electricity. This is done by using turbines. By using an electrical generator, wind energy can be converted into electrical energy. Wind energy is not something that just came out. It has been around for a long time, but now we are using it more.
In 2005, wind accounted for 1 percent of the total electricity production in the world. Germany was the leader in utilizing wind energy, with the U.S. coming in third. In Denmark, wind produces approximately 20 percent of the country’s electricity consumption. When surveys were taken, 90 percent of the people there wanted more turbines.
There was $17 billion dollars put into the economy in 2008. Wind power was one of the leading sources of power, along with natural gas. As of January 1, 2009, the initial tariff for onshore wind energy was increased to 9.2cent/kWh. Wind energy also has the ability to produce more jobs. The more wind energy we use, the more wind systems will need to be installed. This would allow more jobs to be created, the unemployment rates could drop.
A total of 20,301 wind turbines with 23,903MW of total capacity were installed at the end of the year in 2008. In 2009, wind energy reached more than 9,900 megawatts and the previous year it was 8,400MW. The total capacity was more than 35,000MW, which put the U.S. ahead of Germany.
There may be issues arise when it comes to wind energy, especially with wind farms. The concerns should always be weighed against the threats of climate change and fossil fuel depletion. Many people overlook the potential of wind energy. It is becoming cheaper to produce wind energy and it may become the cheapest to produce on a larger scale.
