Here's some interesting facts about solar power, the use of energy in our world, and some bits of solar history:
The Sun's Power
It is estimated that in one hour, more than enough sunlight hits the earth to provide energy for the whole world’s population – for a year.
Sunlight travels to the earth in about eight minutes from 93,000,000 miles away.
Solar energy does not produce pollution, will never be used up, and is free once a system is in place to harness its power.
It is possible for solar energy to be collected during cloudy, rainy, and cold weather.
Electricity in our World
About two billion people in the world are currently without electricity.
Americans use 26 percent of the world's energy.
It is estimated that about 20 percent of the electricity used in the United States is for lighting.
A Bit of Solar Power History
Ancient Greeks and Native Americans warmed structures by facing them toward the sun.
In 1866, a French engineer, Auguste Mouchout, powered a steam engine with solar energy. He later connected the steam engine to a refrigeration device, showing that solar power could make ice.
In 1954, Bell Laboratories scientists developed a photovoltaic cell capable of converting sunlight into electricity.
In 1958, the Vanguard I was launched. It was the first satellite that used solar energy to make electricity.
And Right Now...
The main reason for Daylight Saving Time is to save energy by keeping people’s waking hours more in line with natural sunlight, thereby cutting lighting electricity costs.
The cost of equipment to make use of solar power continues to drop while the technology's efficiency and options continue to increase.
It is estimated that there are more than 10,000 homes in the United States that meet all of their energy needs from solar power.
Solar energy is being used to power many homes, businesses, and even villages in Africa.
