If you are interested in getting to know how solar energy works and reducing a little from your home energy bill, facts about solar energy will help you. Solar energy is a inexhaustible resource and of the oldest method of energy use that is available at nowadays. The critical fact about solar energy is that the sun s rays are so powerful that if we are to convert that into energy it would mean that Earth will never run out of energy for at least another 4.5 billion years according to scientists. The sun does not create any other hazardous by products which could harm the natural environment.
During the early fifties solar energy was looked upon as an substitute to man made energy resources. Over some research it was found energy could be acquired at some cheaper source. With a constant figure of 20% – 25% demand growth year-by-year, the solar energy demand increases for last two decades. Solar energy is able to support household appliances, lighting and water heaters. As of the minute, solar energy is more heavily priced but in the near future with the growth in technological studies, it will bring down the costs and also growth its efficiency. Solar energy is to generate 2.5% of the world s energy consumption by 2025. Solar energy is the fastest growing technology.
There are some primary facts about solar energy that one needs to be acquainted to; solar energy is measured in kilowatt hours and 1 kilowatt=100 watts. One kilowatt hour is equal to the amount of electrical energy which is required to burn 100 watt light bulb for approximately 10 hours. An average American home consumes 866 kilowatt hours per month. The Residential Energy consumption Survey conducted in 2001 shows that an annual energy bill was around $2000.
A reduction in unit costs has contributed towards an increase in growth rates and thereby making it an important energy resource. Since 2000, solar energy has been expanding at an incredible rate of 40% per annum. Solar energy is going at a raising rate in the developing countries too as the consumption of fossil fuel has doubled over the years. When compared to solar energy which is unlimited, fossil fuel reserves are decreasing. Setting up solar energy gadgets is relatively easier in the more remote areas in comparison for setting up an expensive power grid structure. A disadvantage of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas. These are just some of the facts about solar energy.
