Fossil
fuels such as oil, gas and coal are believed to have been contributed
to climate changes. Thus, we need to move to friendly energy sources,
renewable energy.
Two
prominent renewable energies are wind and sun. Denmark have chosen
wind as energy solution with several reasons:
-
wind available for 24 hours, not only in daylight
-
less pollution
-
more efficient
-
produce more energy
In
term of wind power generator per capita (MWH per person), top 10
countries are:
-
Denmark, 2.29 MWH per person
-
Germany, 1.44
-
Ireland, 1.34
-
Spain, 1.30
-
Canada, 0.85
-
USA, 056
-
United Kingdom, 0.57
-
France, 0.40
-
Italy, 0.38
-
China, 0.26

Denmark
is clearly pioneer and leader in using and acquiring the cutting edge
technology of wind energy in the world.
Technology
progress through the years, now, we aware that renewable energy is
more effective than fossil fuel energy in term of cost.

If
we compare wind to solar energies, wind power is cheaper than solar
energy. Wind power cost around US$ 45 per megawatt hour, while solar
energy cost US$ 48 per megawatt hour.
Cost
will be reduced in coming years due to invention in wind turbine
technology and storing energy capacity.
USA
promoted renewable resources energy, especially in the state of
California. If we buy a brand new house, the property owners will
offer us solar panels for electricity.
Did
your state or country start to use wind or solar energy sources?
