Solar energy is a clean renewable source of energy that is harnessed or used by humanity directly or indirectly for millennium. The objective of solar energy is to harness the suns power and converting it into electricity. The sun gives off enough output that if we were to harness its energy for one day we would have enough energy to power depends upon for a full year. Solar energy is an energy we don’t really need to worry about running out or diminishing in the near future. According to scientists the sun should keep burning for another 4.5 Billion years. Another advantage would be that the sun does not produce any harmful byproducts or pollutants that could harm the environment.
Mankind has used the sun for years now. Man has used the sun for drying of meats or skins or just having direct sunlight as a heat source. Noisy, 1950’s solar power was starting to be viewed as clean new form of electricity. Due to technology restraints a realistic look at cheap efficient panels has really only now been a reality.
– Solar energy is a clean renewable energy that is better for the environment and produces no pollutants like traditional energy forms.
– Demand for solar electric energy has consistently grown by 20-25% per year in the last 20 years.
– Solar is capable of powering household appliances, lighting, and water heaters.
– Solar is often more affordable in future with new scientific researches that should decrease the costs and increase the efficiency of the solar energy.
– Solar could generate 2.5 percent of the world’s electricity by 2025.
– Solar Energy is among the fastest growing technologies.
Solar Energy Usage Facts
– Solar is measured in kilowatt hours (KW) 1 kilowatt =100 watts.
– 1 Kilowatt hour = Amount of electricity needed to burn a 100 watt light bulb for 10 hours.
– The average American household uses approximately 866 kilowatt hours per month.
– Based on the Residential Energy Consumption Survey from 2001 the annual energy bill for an American home was $2000 a month.
– Solar energy’s reduction in unit costs has yielded its growth rates and therefore solar energy has potential to become very important energy source.
– Since the year 2000 solar has been really expanding in United States, growing at an incredible average pace of 40% per year.
