As anyone who has ever spent a day playing or working in the summer heat can tell you, the sun is an incredibly impressive source of energy. Even from a distance of 93 million miles, then sun's rays are still power-packed. That's why TVA is using technology that collects the sun's rays and turns it into electricity. The electricity created this way is called solar power.
Solar power is an environmentally friendly alternative to some other power-generating methods. This is because the sun's energy is renewable, which means we will never run out of it.
And solar power production does not create significant air, water, or land pollution. The United States Environmental Protection Agency says that every year the sun bombards the earth with 1,000 times the energy we get from burning fossil fuel. The trick is to figure out how we can harness that incredible energy.
