What is solar energy?

Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the potential to satisfy all future energy needs.

How does solar work?

The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.

How much solar power does the US have?

Currently, the U.S has a solar power capacity of around 97.2 gigawatts. Only about 3% of the electricity generated in the U.S. comes from solar energy. The rest comes overwhelmingly from conventional fossil fuels like coal and natural gas.

How do people use solar energy?

People now use many different technologies for collecting and converting solar radiation into useful heat energy for a variety of purposes. Solar photovoltaic (PV) devices, or solar cells, convert sunlight directly into electricity. Small PV cells can power calculators, watches, and other small electronic devices.

What are the basics of solar energy technology?

Learn solar energy technology basics: solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.

Does solar power work in local areas?

Local areas must be studied to determine whether or not solar power would be effective in that area. Sunlight must be abundant and consistent for solar energy to be an efficient choice. In most places on Earth, sunlight’s variability makes it difficult to implement as the only source of energy.
