Home Generator – Solar Energy; The Real Facts
Most power plants in the United States and throughout world are using fossil fuels to operate and produce electricity. Fossil fuel has been utilized as an energy source as for an extended time as man has discovered to generate power. Fossil fuel has been around for ages and when man began utilizing this energy sources, no one considered the consequences. Fossil fuels will run out and there will be a shortage of it in not too distant future. This shortage in fossil fuel will have its effect on our everyday lives and various industries. Today, we observe a few of these effects already, fossil fuel prices are increasing and electricity is getting more costly. Although fossil fuels are more scarce, to need for fossil fuels will nonetheless be here and won’t reduce in not too distant future. To fix this scarcity of fossil fuels, we’ll need to look for some other alternatives for our energy demand.
Fortunately, alternative energy sources are growing in awareness. For example, locations with high water falls are testing on building a hydro-electric power plant, which turns out to be successful. Other areas 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 one of the energy sources that’s increasing in awareness. Solar energy has steadily been rising. Today, solar energy is popular in the US and the benefits are many. The sun, which is our solar energy source, has a life span that’s believed to be another 4.5 billion years. It’s sensible to state that this energy source is almost endless.
Conversion of Solar Energy
You will find 2 methods of conversion of solar energy. First is the direct solar energy which entails only one conversion into a usable form. For instance:
• Sunlight hits the solar cell, transforming it into electricity.
• Sunlight hits the absorber surface of a solar thermal collector, converting into thermal energy which can be utilized to heat homes throughout cold season.
The second is the indirect solar energy which entails much more than one conversion to reach a usable form. For instance:
• Plants use photosynthesis to transform 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
Exactly like any other types of energy resources, solar energy has its pros and cons.
Pros:
• Pollution-free.
• Solar facilities can be operated with bit of extra input or maintenance.
• It is plentiful. As pointed out previously, most of the inhabited areas here on Earth can be reached by sunlight.
Cons:
• Although it’s plentiful, non-tropical locations can receive small sunlight. Thus, power that will be generated in these locations is a minimum.
• Only during daytime therefore not obtainable during night time.
• Photovoltaic cell technologies generate direct current (DC) power which has to be converted to alternating current (AC) power used in distribution grids.
Once massive development of the use of solar energy is materialized, anticipate that every household or industry in the entire world will currently be powered by solar energy. It is not just a dream, it will be a dream come true.
