More and more people are learning about solar energy facts because of interests in creating cleaner and renewable energy sources.
Solar energy can be used for a wide range of things like heating our houses, heating water, and even running motors to cool and air-condition our houses.
To help you learn more about solar energy facts, here are 7 of them to help increase your green energy knowledge.
1. The earth receives and amazing 174 pentawatts of solar radiation every day. But a large portion, about 30%, is reflected back into space, and is unable to be used.
2 The total solar energy absorbed by the atmosphere, ocean, and land masses is about 3.9 exajoules per year.
3. Some people estimate that Africa's Sahara Desert currently receives enough energy per year to cover the our whole global energy consumption 100 times over.
4. The amount of solar energy that reaches the surface of the earth is so big in one year that is about twice as much then will ever be claimed from all of the Earth's nonrenewable resources like coal, oil, uranium, and natural gas.
5. The sun is about 93,000,000 miles away, and if you estimate that light travels at 186,282 miles per second, it would take about eight minutes for light to travel from the Sun to the earth.
6. In the 5th century, Leonardo da Vinci was one of the very first people to ever predict that solar energy could be harvested for the good of society.
7. 2 billion people in the world are without electricity. Think about this the next time you are taking a warm shower.
I hope these solar energy facts encourage you to learn more about this renewable resource. Now is a great time to learn how to harvest this energy at your own home.
