Solar Energy

The Solar Energy as one of the alternative sources in life and which produced by the sun. Nowadays, air pollution is the biggest problem in our life and this energy is safer and cheaper.

There are some advantages of this energy. First, the price of this energy can’t be change in the future, unlike other prices for oil or gas. Secondly, solar power is a friend for the environment and it has zero pollution. Another useful thing is that it helps when the peak shaving reached highest during the use. There are two main ways to use the power of the sun to reduce energy costs in your home. You can use the heat from the sun's rays to heat your home or your domestic hot water, or to produce electricity to power lights and appliances. Sunset is a problem and storing the solar made the batteries prices more expensive. They found a way to keep power at night by adding cobalt and phosphates to water and pass through a solution a mild current with a glass electrode. The researchers advise that water must be and split to hydrogen and oxygen during night because hydrogen could burn or come out through the cell.

Photovoltaic cells (PV) are flat electronic devices which will convert the sun light immediately to electricity. Typical commercial photovoltaic cells convert 10-20% of the sunlight that falls on them to electricity. A separate report from industry analyst firm NanoMarkets forecasts that the thin-film PV market will produce the equivalent of 26 gig watts by 2015 and generate over $20 billion in revenue in that same time frame(Jusko).

In conclusion, solar energy is the future source for the earth and it can protect the environment for the next generation.
