What is solar energy and why is it important?

Solar energy is a clean, abundant source of energy that harnesses the sun's radiation to generate electricity and heat. It is a cornerstone of renewable power and has emerged as a key player in the global transition towards sustainable energy systems.

What is solar energy?

Solar energy is radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements.

What are the advantages of using solar power?

Solar energy offers several benefits. It is renewable and sustainable, as it harnesses the sun's energy without depleting natural resources. Additionally, solar power generation produces no direct emissions or pollutants, making it an environmentally friendly option.

How does solar power benefit the environment?

Solar power benefits the environment. Adopting renewable energy helps to improve air and water quality and helps the country reduce greenhouse gas emissions that exacerbate climate change. DOE partners with national labs to develop innovations that lower the costs of solar energy.

What is solar energy used for?

Solar energy is the most environmentally friendly and widely available renewable energy source. This energy may be used by modern technology for a multitude of purposes, including generating electricity, giving light, and heating water for household, commercial, and industrial use.

How does a solar energy system work?

A solar thermal system produces hot water or air, cooks food, dries materials, etc., with the help of the sun's heat. In a solar electric energy system, solar photovoltaic uses solar radiation to produce electricity for household appliances as well as commercial and industrial buildings.
