Alternative Power: Great Info About Solar Energy
If you are interested in getting to know how solar energy works and reducing a little from your household energy bill by using it as an alternative power source, facts about solar energy will help you. Solar energy is a renewable resource and of the oldest method of energy consumption that is available at this time. 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 doesn’t make any dangerous by-product that could be harmful to the environment.
During the early ’50s solar energy was looked upon as a good alternative to man made energy resources. Through 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 energy is able to support home devices, lighting and water heaters. As of the minute, solar energy is more heavy priced but in the near future with the growth in technological researches, it will bring down the prices and also increase 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 fundamental 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 electrical energy which is required to burn 100 watt light bulb for roughly 10 hours. 866 kilowatt is the consumption by an average American home. 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 increase in growth rates and thereby making it an important 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 usage of fossil fuel has doubled over the years. When compared to solar energy which is an inexhaustible alternative power source, fossil fuel holds are decreasing. As compared to expensive power grids, setting up solar energy gadgets (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 oil, coal and gas.
