Finding The Facts About 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 renewable resource and of the earliest method of energy consumption that is available at nowadays. The critical 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 4.5 billion years according to scientists. Sun never create any hazardous by-product which could harm the environment.
During the early 1950s solar energy was looked upon as an substitute to man made energy resources. Through much research it was found energy could be received 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 household gadgets, lighting and water heaters. As of the moment, solar energy is more heavily priced but in the near future with the increase in scientific studies, 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 energy is the fastest growing technology.
There are some primary 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 total of electrical energy 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 consumption Survey conducted in 2001 shows that an annual energy bill was around $2000.
A reduction in unit costs has added towards an increase 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 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 unlimited, fossil fuel reserves are decreasing. As compared to expensive power grids, setting up solar energy 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.
