Solar Power-The Energy of the Future

Abstract: Solar energy, once thought impossible for use as a consumer power source, is steadily growing in its applications and affordability. Laboratories and government agencies are optimistic that solar power will soon be economically feasible for nations worldwide. Such uses as passive solar heating and cooling of homes, and the use of photovoltaic (solar electric) cells to run "big energy" appliances are currently out of reach for the everyday consumer. Others, such as the use of photovoltaic cells to power portable computers, lanterns and other items, are more and more becoming a solid investment for the general public. Companies that produce such items are reaching their audiences through sites on the world wide web and through mail-order-catalogues.

Solar power, once considered as futuristic and unobtainable as the moon, is fast becoming a reality for nations whose fossil fuel supplies will soon disappear. Solar energy is pollutionless and is a fuel source of virtually infinite abundance. It may be the only stead-fast source of energy that is usable by our fossil fuel-burning society.

According to an article recently published on the World Wide Web by the Untied States Dept. of Energy-residential appliances, most of which can be run on solar power, consume 90 % of all energy used in the residential sector. That means, if a household used photovoltaic (solar electric) panels solely to run their appliances, such as a refrigerator, microwave, or used passive solar energy for heating water, they could reduce their annual energy purchases and strain on fossil fuel supply by an average of $1,750 dollars per person.

According to the same article, "for most of the United States the electrical needs for a typical family could be theoretically met by using the solar energy shining on 30 sq. ft. of roof space." (U.S.-Facts) Going even further, if the U.S. was to have to rely solely on solar power for its energy needs, it could supply the entire country with power using solar power covering an area as large as 2 or 3 counties in Nevada. To be effective, these systems would only have to be 10 % efficient, a rate that has already been met in laboratories.

As well as keeping our current energy use in check, we must think about growing populations and the threat they will pose to our shrinking resources.
