How To Save The Earth And Lower Your Power Bills By Using Solar Power Energy

Solar Power Energy is a renewable natural resource gained by harnessing the light and heat obtained from the sun using various types of technologies. In fact, most of the energy used on Earth is in some way derived from the sun. For example, when plants use sunlight to grow and to carry out photosynthesis, they are making an indirect use of sunlight. In this case we are referring to the conversion of the sun’s rays into a usable form of energy such as electricity and heat.

Discovery of this energy cannot be traced to any particular era, but its inception was probably caused by the Industrial Revolution. During the Industrial revolution a lot of people were concerned with the limited supply of fossil fuels; such as coal and oil. So, people begin looking for alternative methods to generate power. Between 1892 – 1905, the Solar Motor Company sold the first Solar Power system worth $2,160.In 1956 the first solar cell was made available to the public, however it was quite expensive at $300 per watt.

Solar energy can be converted into electricity in two ways: Photovoltaic Devices also known as solar cells and Solar Power Plants. Photovoltaic cells depend on semi-conductors such as silicon to directly convert solar energy into electricity. Individual cells are grouped into panels and can be used for a range of applications; such as, calculator batteries and watch batteries. In a solar power plant, heat from the sun is used to warm a fluid and the steam produced, is used to power the generator.

This energy can also be used to power homes, buildings, swimming pools as well as greenhouses. In a home, the home solar power systems are usually installed on top of the roof where it can get direct sunlight. An electric field is created when light falls on the cells. The stronger the sunlight, the more electricity is produced.

Solar Power Energy provides you with lots of advantages. It is a renewable form of energy and it does not emit any harmful green house gases or other pollutants. It is estimated that a single household can save about 1200kg of Co2 yearly. Besides this, sunlight is free and it does not cost you any extra fuel cost. A single PV device can produce approximately 40% of your yearly electricity requirement. Besides this, if you build your own solar panel that produces more electricity than you want, you can sell the excess electricity.

This type of energy is environmentally friendly and at the same time cost effective. It will save you a lot of money and have a positive effect on your cash flow. Also, the tonne of Co2 you save per year can contribute to help the environment and save the earth from global warming.
