Green energy refers to the use of power that is not only more efficient
than fossil fuel but that is friendly to the environment as well. Green
energy is generally defined as energy sources that dont pollute and are
renewable.
There are several categories of green energy. They are anaerobic
digestion, wind power, geothermal power, hydropower on a small scale,
biomass power, solar power and wave power. Waste incineration can even
be a source of green energy.
Nuclear power plants claim that they produce green energy as well,
though this source is fraught with controversy, as we all know. While
nuclear energy may be sustainable, may be considered renewable and does
not pollute the atmosphere while it is producing energy, its waste does
pollute the biosphere as it is released.
The transport, mining and phases before and after production of
nuclear energy does produce and release carbon dioxide and similar
destructive greenhouse gases. When we read of green energy, therefore,
we rarely see nuclear power included.
Those who support nuclear energy say that nuclear waste is not, in
fact, released into our earths biosphere during its normal production
cycle. They stress as well that the carbon dioxide that nuclear energy
production releases is comparable, in terms of each kilowatt hour of
electricity, to such sources of green energy as wind power.
As an example of the green energy production the average wind
turbine, such as the one in Reading England, can produce enough energy
daily to be the only energy source for 1000 households.
Many countries now offer household and commercial consumers to opt for
total use of green energy. They do this one of two ways. Consumers can
buy their electricity from a company that only uses renewable green
energy technology, or they can buy from their general supplies such as
the local utility company who then buys from green energy resources only
as much of a supply as consumers pay for.
The latter is generally a more cost - efficient way of supplying a
home or office with green energy, as the supplier can reap the economic
benefits of a mass purchase. Green energy generally costs more per
kilowatt hour than standard fossil fuel energy.
Consumers can also purchase green energy certificates, which are
alternately referred to as green tags or green certificates. These are
available in both Europe and the United States, and are the most
convenient method for the average consumer to support green energy. More
than 35 million European households and one million American households
now buy these green energy certificates.
While green energy is a great step in the direction of keeping our
environment healthy and our air as pollutant free as possible, it must
be noted that no matter what the energy, it will negatively impact the
environment to some extent.
Every energy source, green or otherwise, requires energy. The
production of this energy will create pollution during its manufacture.
Green energys impact is minimal, however.
