nearly all forms of renewable energy come directly or indirectly from the sun. List forms of renewable energy. describe how the sun creates the various forms of energy you listed. if you have any forms of renewable energy that do not come from the sun, identify their sources.
1. Solar energy - The sun generates solar energy by emitting photons, which are captured by solar panels and converted into electricity.
2. Wind energy - The sun heats up the Earth's atmosphere, creating temperature differences that cause air movement, known as wind. Wind turbines capture this wind and convert it into electricity.
3. Hydroelectric energy - The sun's heat causes the water cycle, with water evaporating, forming clouds, and then falling back to the Earth as rain. This rain fills rivers and reservoirs, which can be used to generate hydroelectric power.
4. Biomass energy - Plants use photosynthesis to convert sunlight into energy. When biomass materials like wood, crops, and waste decompose or are burned, they release energy in the form of heat or electricity.
5. Geothermal energy - Heat from the Earth's core, which is derived from the decay of radioactive materials, creates geothermal energy. This heat can be harnessed for electricity generation or heating.
6. Tidal energy - Tides are primarily caused by the gravitational pull of the moon and sun. When tides move in and out, they can be used to generate tidal energy through turbines.
7. Wave energy - Waves are formed by wind passing over the ocean, which is ultimately driven by solar energy heating the Earth. Devices like wave energy converters can capture the motion of the waves and convert it into electricity.
One form of renewable energy that does not directly come from the sun is kinetic energy, which can be harnessed from sources like moving water or wind, without relying on solar radiation.
