"Solar power is clean energy"
"Solar power provides unlimited supply of energy" Did you know that the earth receives in 1 hour the total power used by the world in an entire year?
Solar radiation reaches the Earth's upper atmosphere at a rate of 1366 watts per square meter (W/m2).Did you know that the earth receives in 1 hour the total power used by the world in an entire year?
Tropical oceans absorb 560 trillion gigajoules (GJ) of solar energy each year, equivalent to 1,600 times the world’s annual energy use.
A solar box cooker traps the sun's energy in an insulated box; such boxes have been successfully used for cooking, pasteurization and fruit canning. Solar cooking is helping many developing countries, both reducing the demands for local firewood and maintaining a cleaner breathing environment for the cooks.
Solar electric generation has the highest power density (global mean of 170 W/m2) among renewable energies.
There are two new studies looking into the possibility of creating "dams" in space that catch the Sun's energy and beam it into power grids on Earth via laser or a microwave beam. (SPACE.com)
Two billion people in the world have no access to electricity. For them, solar power is a practical way to deliver at least a little electricity in rural places around the world. (reference http://localdc.com/solar-trivia.htm)
NASA'S Martian Rovers, Spirit and Opportunity have roamed the red planet's surface for three years (and are still going) operating on solar power alone.
