Using Facts About Solar Energy
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 renewable resource and of the oldest method of energy consumption that is available at present. 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 four point five billion years according to scientists. The sun does not create any other hazardous by products which could harm the natural environment.
During the early 1950s solar energy was looked upon as an substitute to man made energy resources. Through some studies it was found energy could be obtained at some cheaper source. The demand for solar energy has grown substantially within the range of 20-25% over the last twenty years. Solar energy is able to support home appliances, lighting and water heaters. As of the moment, solar energy is more heavily priced but in the near future with the increase in technological researches, it will bring down the prices and also increase 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 fundamental facts about solar energy that one needs to be presented 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 around 10 hours. 866 kilowatt is the consumption by an average American home. 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 critical energy resource. Since 2000, solar energy has been expanding at an incredible rate of 40% per annum. Solar energy is going at a progressive rate in the developing countries too as the consumption of fossil fuel has doubled over the years. When compared to solar energy which is infinite, fossil fuel reserves are lessening. As compared to expensive power grids, setting up solar energy appliances is relatively easy. A disfavor of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas.
