For millions of years, radiation from the Sun has supported life on Earth. Solar energy is harnessed using a range of modern technologies to generate electricity, thermal energy, and solar architecture.
Geothermal energy is heat within the earth's crust that originated during the original formation of the planet and the radioactive decay of materials. It's used for generating heat and electricity.
Wind energy refers to the energy generated from the force of the wind. Wind energy has historically been used in sails, windmills, and windpumps, but nowadays wind turbines are used to generate electricity.
Biomass is made of material that comes from wood, energy crops, agricultural residues, and waste from industry, farms, and households. It's used as fuel to produce heat or electricity.
Hydropower uses falling or fast-running water to generate electricity or to power machines. The energy is generated by creating a dam or diversion structure to alter the natural flow of a water body.
