Facts about solar energy help you to understand how solar energy works and how you can save some dollars without having to run a high energy bill. Solar energy is a renewable resource and of the oldest method of energy use that is available at present. The significant 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 alternative to man made energy resources. Through much studies it was found energy could be acquired at much 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 household gadgets, lighting and water heaters. As of the moment, solar energy is more heavy priced but in the near future with the increase in technological researches, it will bring down the prices and also growth its efficiency. Solar energy is to generate 2.5% of the world s energy use by 2025. Solar energy is the fastest growing technology.

There are some primary 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 electricity which is required to burn 100 watt light bulb for roughly 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 added towards an increase in growth rates and thereby making it an significant energy resource. Since 2000, solar energy has been expanding at an incredible rate of 40% per annum. Solar energy is going at a increasing rate in the developing countries too as the use of fossil fuel has doubled over the years. When compared to solar energy which is inexhaustible, fossil fuel holds are lessening.  Setting up solar energy gadgets is relatively easier in the more remote areas in comparison for setting up an expensive power grid structure. A disfavor of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas. These are just a few of the facts about solar energy.
