Searching For The Facts On Solar Energy

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 inexhaustible resource and of the earliest method of energy use that is available at present. The important 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 some studies it was found energy could be received 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 home gadgets, lighting and water heaters. As of the moment, solar energy is more heavily priced but in the near future with the growth in scientific researches, it will bring down the prices and also increase 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 basic 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 necessary to burn 100 watt light bulb for around 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 significant energy resource. After year 2000, solar energy has shown a growth rate of 40% per annum. Solar energy is moving 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 holds are diminishing. Setting up solar energy appliances 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.
