Renewable Energy
The
renewable source of energy is an energy that could be
regenerated in short period of time.
Although generating electricity from renewable source (wind,
solar. Biomass, etc) have no adverse impact on environment, but
the overall use of this energy has decreased since its peak in
1996. Its production became only 6 quads in 2002. Each quad is
equal to 5.9 quadrillion Btu.
People used wood to generate heat hundreds of years ago. In the
past about 90 percent of energy source was wood.
Low
price of fossil fuel and its convenience attracted people to
switch from wood to fossil fuels.
This
cheap prices of fossil fuel prevented people to use the
renewable source of energy. Attracting the power industry to
shift to renewable fuel as source for electricity production
needs legislation. Finally, in short term while cheap fuel is in
hand, possibility to increase renewable energy is not in sight
in the United States.
Renewable energy in other countries, where sun shines most of
the year or at windy areas, is proving economical. But in U.S.A
where there are clouds and days are quiet (no wind area) and
dams are made to control floods, demand increase for renewable
energy is not proved to be commercial. In 2002 about 5.9
Quadrillion BTu (Quads) of energy produced was in the form of
renewable energy.
