Development of newly installed wind power capacity in Germany and
projects until 2030. (
Data based on: Messe Hamburg Wind Energy, 2006
)
produce around 100 billion kilowatt hours per year. Overall wind energy could cover
between 25 and 30% of Germany's electricity requirements by 2030.
According to the American Wind Energy Association (AWEA) about 20% of the
US American electricity demand can be covered by wind power by 2030. To reach
this goal the annual installations of new wind turbines in the USA would need to
ramp up to more than 16 gigawatts by 2018 compared to 8.5 gigawatts in 2008.
That would lead to a cumulative total power of 300 gigawatts. In contrast to
Germany, more than 80% of the installation will be land-based.
The possible installations for the European Union are in the same range. The
European Wind Energy Association (EWEA) projects that the total installed
capacity by 2030, will be between 200 and 350 gigawatts. These fi gures provide
convincing evidence that wind power will become one of the key pillars of a
climate-compatible electricity economy. As other countries are in the process of
following the US and Europe's model, wind power could very possibly provide 25
to 35% of the world's electricity needs by 2050.
