Home Generator - Solar Energy: The Real Facts

Most power plants in the United States and throughout world are making use of fossil fuels to run and generate electricity

. Fossil fuel has been used as an energy source as long as man has learned to produce power. Fossil fuel has been in existence for a long time and when man began using this energy sources, nobody considered the consequences. Fossil fuels will run out and there will be a scarcity of it in near future. This shortage in fossil fuel will have its effect on our daily lives and various industries. Nowadays, we observe a few of these effects already, fossil fuel prices are increasing and electricity is becoming more expensive. Although fossil fuels are much more scarce, to need for fossil fuels will nonetheless be here and won't reduce in near future. To solve this scarcity of fossil fuels, we'll have to search for other possibilities for our energy demand.

Fortunately, alternative energy sources are growing in interest. For instance, locations with high water falls are testing on developing a hydro-electric power plant, which works out to be successful. Other locations with high wind speed make use of a power wind mill that can change wind power into electricity. Also thermal and tidal powers are great alternatives.

Solar energy is also among the energy sources that's gaining in awareness. Solar energy has gradually been growing. Nowadays, solar energy is widely used in the US and the advantages are many. The sun, which is our solar energy source, has a life span that is believed to be another 4.5 billion years. It's fair to state that this energy source is almost endless.

Conversion of Solar Energy

You will find two ways of conversion of solar energy. First is the direct solar energy which involves only one conversion into a usable form. For instance:

*Sunlight strikes the solar cell, transforming it into electricity. *Sunlight hits the absorber surface of a solar thermal collector, converting into thermal energy which can be used to heat homes during cold season.

The second is the indirect solar energy which involves more than one conversion to attain a usable form. For example:

*Plants make use of photosynthesis to convert solar energy to chemical energy, which can be burned later as fuel to produce electricity (also known as bio-fuel technology) *Hydroelectric dams and wind turbines are indirectly supplied by solar energy via its interaction with the Earth's atmosphere.

Pros and Cons of Solar Energy

Just like any other types of energy resources, solar energy has its pros and cons.

Pros:

*Pollution-free. *Solar facilities can be run with bit of extra input or maintenance. *It's plentiful. As mentioned earlier, most of the inhabited areas here on Earth can be hit by sunlight.

Cons:

*Even though it's abundant, non-tropical areas can acquire small sunlight. Thus, power that will be generated in these areas is a minimum. *Only during daytime thus not obtainable during night time. *Photovoltaic cell technologies generate direct current (DC) power which needs to be transformed to alternating current (AC) power used in distribution grids.

As soon as huge development of the use of solar energy is materialized, anticipate that each household or industry in the world will currently be powered by solar energy. It's not just a dream, it'll be a dream become a reality.
