E. Where is the solar energy from?

F. The advantages of renewable energy.

1.                          

     When speaking about renewable energy, we are talking about power which derives  its energy from

resources which will not be diminished from the use. Renewable energy is a substitute for the

nonrenewable energy of fossil fuel.

2.                         

     One fundamental advantage of renewable energy, and environmentalists'  favorite reason to promote

its use, is that there are no greenhouse gases or other pollutants give out as there are with the burning

of fossil fuels. Renewable energy, or solar, water and wind power, are certainly not new although they

have received much attention recently because they will not cause pollution. Environmental friendly

power sources such as wind, solar and water power have been used in both developing and developed

countries for a long time because they are cheap and clean, but they have yet to be used as a primary

source of energy for any big urban area.

3.                       

     The generation of power from renewable energy sources has become somewhat more common in

recent times as people have increasingly become aware of issues such as climate change due to fossil

fuel byproducts and the political or social worries about nuclear power. There are numerous countries

and nonprofit, environmentally conscious organizations that are  supporting the use of renewable energy.

4.                      

     The flow of renewable energy has to do with naturally occurring phenomena. Tides, sunlight, wind

and heat are all created by geothermal events and all are sources of energy has unique characteristics

related to where and how we can use them.

5.                      

     Most technology which transforms renewable energy into power which we can use is solar power

either directly or indirectly. The atmospheric system of the earth keeps balance so that the heat which

spreads out into space is equal to the amount of radiation received from the sun. The quantity of energy

contained in the atmosphere approximates the earth' s climate. The bodies of water of the earth, or its

hydrosphere, absorb much of the radiation which is received from the sun. And much of that absorbed

radiation is in the lower latitudes surrounding the equator.
