Solar energy is a clean, inexpensive, renewable power source that is harnessable nearly everywhere in the world - any point where sunlight hits the surface of the earth is a potential location to generate solar power. And since solar energy comes from the sun, it represents a limitless source of power. Renewable energy technologies generate electricity from resources that are infinite. Compare, for instance, producing electricity with renewable resources to doing so with fossil fuels. It took hundreds of thousands of years for oil, gas and coal to form, so every time one of those resources are burned to create electricity, that finite resource is moved marginally closer to depletion. Using a renewable resource - such as wind, solar and hydropower - to generate electricity, does not deplete that resource. There will always be consistent sunlight shining on Earth's surface, and after turning sunlight into electricity, there is still an infinite amount of sunlight to turn into electricity in the future. That is what makes solar power, by nature, renewable energy.

While the current electricity mix in the United States is still made up largely of fossil fuels like oil and gas, renewable energy sources like solar are steadily becoming a larger part of the country's energy profile. As the cost of solar and other renewable technologies continues to be competitive.
