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 by using it as an alternative power source. Solar energy is a inexhaustible resource and of the earliest method of energy usage that is available at this time. The critical fact about solar energy is that the sun’s beams 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 ’50s solar energy was looked upon as a good alternative to man made energy resources. Over some studies it was found energy could be gained at much cheaper source. The demand for solar energy has grown significantly within 20 to 50 percent over the last twenty years. Solar energy is able to support household appliances, lighting and water heaters. As of the minute, solar energy is more heavy priced but in the near future with the increase in scientific studies, it will bring down the costs and also boost up its efficiency. By the year 2025, it’s expected to generate around 2.5% of the world energy demand via solar energy. This energy can be considered as the quickest 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 total of electricity which is wanted to burn 100 watt light bulb for roughly 10 hours. An average American household consumes 866 kilowatt hours per month. The Residential Energy use Survey conducted in 2001 shows that an annual energy bill was around two thousand dollars.

A reduction in unit costs has added towards an growth in growth rates and thereby making it an significant energy resource. After the year 2000, solar energy has grown at an annual rate of 40%. Solar energy is moving 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 an inexhaustible alternative power source, fossil fuel holds are diminishing.  As compared to expensive power grids, setting up solar energy appliances (like if you’re going to make solar panels) is relatively easy. A disfavor of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas.
