Renewable
Energy versus Fossil fuels
As we discussed before, fossil fuels resources are used
up rapidly without any chance for their bringing back to
initial state.
On the other hand we learned about enormous energy of
sun almost everlasting. Meanwhile, wind, water; forests
and recyclable garbage have a potential of renovation.
Stuffs such as sawdust, leftover crops, even livestock
manure have the ability produce electricity.
Collectively we call them “bio mass”.
Clean energy sources like wind, water, sunlight without
harming the environment, can be used to produce our
needed energy.
In a sharp contrast, burning of fossil fuels in cars and
factories has a great affect on atmosphere.
Air pollution results to so call greenhouse effect.
Gases like carbon dioxide are emitted from burning this
sort of fuels.
Recycling is a way of wasting our money and our
resources drawback as the toxic fluids in solar systems
piping or clearing the forests and crop fields for the
purpose of installing windmills, mirrors, power lines.
Solar cells have similar technology like silicon chips
uses toxic chemicals.
Also, we should mention the limited capacity of some of
these resources for instance. All the stalled solar
systems have a limited power of just 350 MW far less
than energy produced by fossil fuels.
As well, the cost of producing is yet four times the
conventional fossil fueled power plants.
There fore, renewable power plants are not yet a match
to cheaper fossil fueled energy.
Wind has its own drawback, mostly because of land use.
Producing energy for about 1000 homes requires an area
equal to 17 acre.
Birds' collision to blades is another distressing of
wind mills.
Geothermal energy is limited to some points of the
world, have a high rate of corrosion in its piping
network.
Its maintenance and drilling costs have made it a little
bit more expensive that gas fired power plants.
Hydroelectric energy by using dams displaces people and
damages its surrounding farmlands.
Air pollution is main characteristic of fossil fuels.
Fuel changes to sort of environmental impact to better
of environmental impact.
To better compare, it is suggested to prepare a full
list of pros and cons of all available energies.
