Solar energy is a general term used for any method or technique used to obtain and store energy from the sun. Solar technology’s history goes back to 7th century B.C using glass and mirrors to light fires (View an excellent historical timeline for more information). Solar energy can be used to heat swimming pools, run small appliances, power cars, cooking food, and many other practical uses. Solar energy is becoming more and more popular as well as more efficient and economical.
Interesting facts about Solar Energy
* It takes about 8 minutes for the sun to reach the earth’s surface once it has been released from the core.
* The sun’s energy is free and will not be depleted for a long, long time. The sun will start to collapse and eventually burnout in about 5 billion years.
* Albert Einstein was awarded the Nobel Prize in 1921 for his discovery of the law of photoelectric effect – a phenomenon where electrons are emitted from a surface when light shines on it. His studies are the foundational building block for solar cells, imaging, telecommunication networks, and so much more.
* The Mojave Desert in North America has the world’s largest solar power plant, containing 1000 acres of solar reflectors.
* If we covered 15% of the Sahara desert with solar cells, it would generate more energy than the entire world consumes, including fossil and renewable energy sources.

Solar Panels for your Home!
A 1-kilowatt home solar system takes 1 or 2 days to install. The cost of a home solar system varies but is somewhere around $10,000. Prices have dropped dramatically and are continuing to go down every month (solar technology is getting more efficient). Depending on the incentives offered by federal, state, and local governments, solar systems can be a great short term and long term investment. Solar energy systems require very little maintenance and will last for a very long time.
This same 1-kilowatt home solar system will replace approximately 170 pounds of dirty coal from being burned, it will save 105 gallons of water from being consumed and prevent 300 pounds of COS from being released into the atmosphere.
While there continue to be disadvantages to installing solar panels, the technology is improving every day and will very soon be in many different neighborhoods and business communities.
