How Does Solar Energy Work?


Solar power works by absorbing the rays of the sun (shining down at about 174 petawatts into the upper atmosphere). Some of this is captured by clouds, some reflected back into space, and a tiny, tiny percentage is harnessed by solar power panels. Obviously, a cost effective solution to the expense of gas, coal, and electricity we use to power our lives would be increasing the percentage of captured radiation. The sole difficulty with solar energy is, of course, heat retention and continuous power supply from a non-continuous power source (the sun; i.e., how to get energy at night). This can be effectively answered by using retentive materials like water, stone, and earth that can hold the heat at night. If the industry is any indication, people are very interested in this option.

One company had a record breaking month. This means that people are very interested in not only saving the environment and promoting sustainable development, but also saving themselves a few bucks each month. With the economy the way it is, solar energy can work for you and with you to promote a better future for our children and posterity. What do you want your generational legacy to be?
