Meet the Sun power people!
Almost all the energy to power our planet comes from the Sun. But instead of using the kind of solar energy stored up in coal and oil, why not grab it directly from the source?
Eliminate the "middle man"In the United States, most of the electricity we use is made by burning coal or oil. Unfortunately, burning coal and oil produces carbon dioxide, a greenhouse gas that adds to global warming.
Some electricity, though, is made using clean sources of energy like wind and sunlight. We need to be making a lot more electricity this way.
Many people are now putting solar electric systems on their houses. Solar panels covered with solar cells, sort of like little glass wafers, are installed on the roof. When sunlight strikes them, they turn some of it into electricity, which is fed through wires into the home’s electrical circuits.
Solar panels covering even a small area on the roof can supply a good part of the electricity to run the refrigerator, lights, heating, TV, and other energy-hungry devices in the house. Making electricity from sunlight does not produce carbon dioxide and does not add to global warming. And after the solar panels are produced, paid for, and installed, the electricity is free!
In California, people are volunteering to help install solar panels on the homes of those who otherwise could not afford to buy them. The program is called Single-family Affordable Solar Homes, or SASH. The organization that sponsors the SASH program is called GRID Alternatives.
During special events, called “Solarthons,” volunteers spend a day installing solar electric systems on homes. The group also works to raise money to expand GRID Alternatives' work throughout California.
So far, they have installed 540 solar electric systems, which are reducing each family’s electrical bills by 75%. Over the next 30 years, these systems will prevent about 46,668 tons of greenhouse gases from being released into the atmosphere.
