why wind energy
wind energy is one of the most promising energy technologies for today, for the 21st century, and beyond.
wind energy is clean
wind turbines emit no pollutants.
a modern 600 kw wind turbine in an average location will annually displace 1,200 tones of carbon dioxide from other electricity sources, i.e. usually coal fired power stations. the energy produced by a wind turbine throughout its 20 year life-time in an average location is eighty times larger than the amount of energy used to build, maintain, operate, dismantle, and scrapping it again. in other words, on average it takes only two to three months for a wind turbine to recover all the energy required to build and operate it.
wind energy is abundant
the energy in the wind is a truly sustainable resource. wind will not run out.
already, wind energy is covering 7 per cent of danish electricity consumption, a figure that will increase to at least 10 per cent by 2005.
the wind resources above the shallow waters in the seas around europe could theoretically provide all of europes electricity supplies several times over.
wind energy makes a difference
wind turbines have grown dramatically in size and power output.
a typical danish wind turbine of 1980 vintage had a 26 kw generator and a rotor diameter of 10.5metres. a modern wind turbine has a rotor diameter of 43 meters and a 600 kw generator. it will produce between 1 and 2 million kilowatt hours in a year. this is equivalent to the annual electricity consumption of 300 to 500 european households. the latest generation of wind turbines has a 1,000-1,500 kw generator and a 50-64 meter rotor diameter.
europes largest wind park in carno, wales produces the equivalent of the electricity consumption of 20,000 homes. in europe more than 3,000 megawatts of wi...
