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 consumption that is available at present. The important 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 1950s solar energy was looked upon as an substitute to man made energy resources. Over some research 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 heavy priced but in the near future with the increase in technological researches, it will bring down the prices and also increase its efficiency. By 2025, it is expected to generate 2.5% of the world energy demand through solar energy. Solar energy can be considered as 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 electricity which is needed 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 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 infinite, fossil fuel holds are lessening. Setting up solar energy appliances 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.
