Mayo Renewable Energy
brings to reality wind energy projects, both new and
conversions, whether a single turbine or a complete wind
farm.
WIND POWER
Wind power is the conversion of wind energy into a
useful form of energy, such as electricity, using wind
turbines. At the end of 2008, worldwide nameplate
capacity of wind-powered generators was 121.2 gigawatts
(GW).
In 2008, wind power produced about
1.5% of worldwide electricity usage; and is growing
rapidly, having doubled in the three years between 2005
and 2008. Several countries have achieved relatively
high levels of wind power penetration, such as 19% of
stationary electricity production in Denmark, 11% in
Spain and Portugal, and 7% in Germany and the Republic
of Ireland in 2008. As of May 2009, eighty countries
around the world are using wind power on a commercial
basis.
Large-scale wind farms are connected
to the electric power transmission network; smaller
facilities are used to provide electricity to isolated
locations. Utility companies increasingly buy back
surplus electricity produced by small domestic turbines.
Wind energy as a power source is attractive as an
alternative to fossil fuels, because it is plentiful,
renewable, widely distributed, clean, and produces no
greenhouse gas emissions. However, the construction of
wind farms (as with other forms of power generation) is
not universally welcomed due to their visual impact and
other effects on the environment and human health.
ECONOMICS
Wind power generation has negligible fuel costs and
relatively low maintenance costs.
