Solar green energy

How is solar power generated?

Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity. It is one of the fastest-growing renewable energy technologies and is playing an increasingly important role in the global energy transformation.

How does solar energy affect the environment?

Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. However, producing and using solar energy technologies may have some environmental affects.

What is solar energy?

Solar energy is a form of carbon-free, renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use.

What is solar energy used for?

Solar energy is used worldwide and is increasingly popular for generating electricity, and heating or desalinating water. Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity.

Is solar power renewable?

Solar power is renewable by nature. Sunlight is infinite, and enough solar radiation hits the planet's surface each hour to theoretically fill our global energy needs for nearly a year. No matter how much solar power we use to generate electricity, the sun will continue to shine. It doesn’t deplete.

How do solar panels turn sunlight into electricity?

There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
