Key takeaways. Solar energy is energy from the sun that we capture with various technologies, including solar panels. There are two main types of solar energy: photovoltaic and thermal. The "photovoltaic effect" is the mechanism by which solar panels harness the sun''s energy to generate electricity. Want to take advantage of solar energy yourself?
Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use. It is a "carbon-free" energy source that, once built, produces none of the greenhouse gas emissions that
Solar power is a form of energy conversion in which sunlight is used to generate electricity. Virtually nonpolluting and abundantly available, solar power stands in stark contrast to the combustion of fossil fuel and has become increasingly attractive to individuals, businesses, and governments on the path to sustainability.
Solar energy is radiation from the Sun that is 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 energy requirements and could satisfy all future energy needs if suitably harnessed.
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of
Photovoltaics Basics. You''re likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture.
Fast Facts AboutSolar 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. It is fully renewable with few environmental impacts, and
Energy Information Administration - EIA - Official Energy Statistics from the U.S. Government Solar explained - U.S. Energy Information Administration (EIA) An introduction to solar energy and types of solar energy conversion technologies including solar thermal and solar photovoltaics (PV).
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.
