What is Alternative Energy
There is a lot of energy that we can harness if we
only seek to research and develop the technologies needed to do so. We
can get away from the fossil fuels and the old electrical grids by
turning to alternatives to these energy sources.
One of these alternative energy resources is wind power. Wind turbines
continue to be developed that are progressively more energy efficient
and less costly. “Wind farms” have been springing up in many nations,
and they have even become more strategically placed over time so that
they are not jeopardizing birds as former wind turbines did.
Another alternative energy resource is the one that is most well known:
solar energy. This involves the manufacturing of solar cells which
gather and focus the energy given off directly by the sun, and translate
it into electricity or, in some cases, hot water. As with wind energy,
solar energy creates absolutely zero pollution.
Ocean wave energy is seen by governments and investors as having
enormous energy generating potential. A generator in France has been in
operation for many years now and is considered to be a great success,
and the Irish and Scots are running experimental facilities.
Hydroelectric power has been with us for a while and where it is set up,
it is a powerful generator of electricity and cleaner than a grid.
However, there are certain limitations to the availability of the right
places to set up a large dam. Many run-of-the-river, or small and
localized, hydroelectric generators have been set up in recent times due
to this limitation.
Geothermal energy is extremely abundant, since it lies directly beneath
our feet, just a few miles below the earth's surface. This energy is
produced by the heating of water through the actions of earth's
fantastically hot molten core. The water turns to steam, which can be
harnessed and used to drive turbine engines which in turn generate
electricity. Great amounts of research and development should be put
into geothermal energy tapping.
Waste gas energies, which are essentially methane, reverse the usual
energy-pollution relationship by creating energy from waste that lies in
the dumps and from some air pollutants. This gas is used in fuel cells
and can be used in standard gasoline generators.
Ethanol is a gasoline substitute and is created from such things as
wheat, sugarcane, grapes, strawberries, corn, and even wood chips and
wood cellulose. There is controversy over this fuel with regards to its
ever becoming truly economical or practical except in very localized
areas, but technologies for its extraction and admixturing are
continuously being refined.
Biodiesel energy is created out of the oils contained in plants. So far,
the commercial stores of biodiesel have been created using soybean,
rapeseed, and sunflower oils. At the time of this writing, biodiesel is
typically produced by entrepreneurial minded individuals or those who
want to experiment with alternative energy, but commercial interest from
companies is on the rise. It burns much cleaner than oil-based diesel.
Atomic energy is created in atomic energy plants using the process of
nuclear fission. This energy is extremely efficient and can generate
huge amounts of power. There is concern from some people about what to
do with the relatively small amount of waste product atomic energy gives
off, since it is radioactive and takes hundreds of years to decay into
harmlessness.
