1. What are the 7 main types of renewable energy?
- Solar Energy: Derived from the sun’s radiation, it is harnessed through solar panels or photovoltaic cells to produce electricity or heat water.
- Wind Energy: Generated by harnessing the kinetic energy of wind using wind turbines, converting it into electrical power.
- Hydropower (Hydroelectric Energy): Generated from the gravitational force of flowing or falling water, typically using dams or river-based systems to generate electricity.
- Geothermal Energy: Derived from the heat within the Earth, often harnessed through geothermal power plants or heat pumps for heating or electricity generation.
- Biomass Energy: Generated from organic materials like wood, agricultural residues, or organic waste through processes like combustion, producing heat or electricity.
- Tidal Energy: Generated by harnessing the energy of tides in oceans and seas.
