Facts About Solar Energy
Facts about solar energy help you to understand how solar power 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 important fact about solar power 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 studies it was found energy could be acquired at much cheaper source. With a constant figure of 20% - 25% demand growth year-by-year, the solar energy demand increases for last two decades. Solar power is able to support home 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 increase its efficiency. Solar energy is to generate 2.5% of the world s energy consumption by 2025. Solar power 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 electricity which is required to burn 100 watt light bulb for approximately 10 hours. An average American home consumes 866 kilowatt hours per month. The Residential Energy use Survey conducted in 2001 shows that an annual energy bill was around $2000.
A reduction in unit costs has added towards an growth in growth rates and thereby making it an critical energy resource. After year 2000, solar energy has shown a growth rate of 40% per annum. 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 unlimited, fossil fuel holds are lessening. As compared to expensive power grids, setting up solar power gadgets is relatively easy. A disfavor of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas.
Your blog is a breath of fresh air in comparison to the usual rubbish I read on solar energy. Several scams around. Thanks for helping me out.
