The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest, 122 PW, is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth''s surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most of the world''s popu
Solar energy is the energy we get from the Sun. It is a renewable energy source, meaning it won''t run out, and it''s clean, meaning it doesn''t pollute the environment.

Solar energy is radiant energy from the sun—a fully renewable energy resource. We use the solar resource to provide daylight, electricity, and heat in four ways (in order of prevalence):
Energy mix: what sources do we get our energy from? Let''s look at our energy mix today, and explore what sources we draw upon. In the interactive chart shown, we see the primary energy
Check out our Energy Spotlight on solar energy! Solar energy is radiant energy from the sun—a fully renewable energy resource. We use the solar resource to provide daylight, electricity, and heat in four ways (in order of prevalence): Solar PV is the fastest-growing electricity resource in the world.
We use the solar resource to provide daylight, electricity, and heat in four ways (in order of prevalence): Solar PV is the fastest-growing electricity resource in the world. It is fully renewable with few environmental impacts, and the cheapest source of electricity in many countries. (U.S. has 3%)
The sun has produced energy for billions of years and is the ultimate source for all of the energy sources and fuels that we use. People have used the sun's rays (solar radiation) for thousands of years for warmth and to dry meat, fruit, and grains.
Please try again later. Solar energy originates from the Sun, a star at the center of our solar system. The Sun emits energy in the form of electromagnetic radiation, including visible light, infrared, and ultraviolet rays. This radiation reaches the Earth and is harnessed through various technologies to generate electricity or heat for human use.
It is a “carbon-free” energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change. There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).”
Abundance of solar energy globally ensures sustainable power generation. Solar energy sources mainly derive from the sun, where photons are converted into electricity through photovoltaic cells. This renewable energy is an essential player in powering homes and businesses worldwide.
