Use of 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.
