Although Austria is a landlocked country with a distinguished hilly topography, meteorological preconditions permit the utilization of wind power. First calculations on the basis of wind measuring data assessed at the meteorological stations in the early 1980s rendered the surprising result of annually approx. 6,600 to 10,000 gigawatt-hour of technically exploitable wind energy potential in Austria. Austria ranked as the world’s seventeenth largest producer of wind power with an installed nameplate capacity of 995 megawatt in 2008, behind Ireland and ahead of Greece.
History
Back in the 1980s, there were huge private wind measurements and experiments with smaller plants. In 1994, initiated by Councilor Waltner, 110 kilowattwind turbine was set up in St. Pölten. Another wind turbine was put into operation six months later in Zistersdorf. In 1995, the first wind turbine was built with civic participation in Michelbach. In January 1996, the first turbine of the type E-40 with 500 kW was placed in Eberschwang. Not only the absolute largest wind turbines were placed there, but with two plants the first „wind farm“ was established. In the course of 1996, no signs of new funding arrangements had emerged. It led by the end of the year in a panic reaction from the first „boom“ for wind power. 36 wind turbines with 12 MW and an annual total of 18 million kW of work hours had been set up between New Year's Day and New Year's Eve. After 1996, there were, only in exceptional cases, economic conditions for individual projects, including the wind park in Zurndorf with six plants. The pressure of individual countries and the idea that desired objectives could be reached nationwide cheaper than by any nation-state alone resulted into negotiations between federal and state governments to a new nationwide Green Electricity Act 2002 in spring 2002. Wind turbines with a capacity of a total of 276 MW were built in 2003. The plant output tripled from 139 MW to 415 MW within a year.
According to manufacturers, the life span of wind turbines amounts to 25 years. Important influences on the life span are site specific and the quality of the maintenance of the turbines.
External costs
are not a part of the investment and operation costs, and are paid by the tax payer and therefore by the public. Examples of external costs for fossil fuel and nuclear electricity production are political and military securing of the access to these energy sources, costs of green house gas emissions, cleaning up of spilled oil, police operations during the transporting of nuclear wastes and other similar activities. There are no external costs for the production of electricity from wind. Wind power is a product with no hidden costs and economically the most inexpensive form of energy production.
Property for wind turbines
Most of the property owners are farmers. They have an additional source of income by leasing their land to the wind park operator. The prices paid for property leases for wind turbines are many times more than would normally be earned by farming the property. A wind turbine needs an area of up to 500 square metres and the rest of the property can still be farmed without any problem. A wind turbine can also be easily and quickly dismantled.
Costs of electricity production
According to the costs for infrastructure, a kW of installed capacity costs between 880 € and 1,487 €..
Production of wind power does not release any pollutants. A wind park with 6 MW installed capacity will reduce approximately the following emissions yearly:
