Solar energy is energy generated from the sun’s heat or sunlight. Solar power is energy captured from the sun which is converted into electricity, or used to heat air, water, or other fluids.
Bioenergy is derived from biomass to generate electricity and heat, or to produce liquid fuels for transport. Biomass is any organic matter of recently living plant or animal origin, such as agricultural products, forestry products, municipal and other waste.
Wind energy is generated by converting wind currents into other forms of energy using wind turbines. Wind turbines convert the force of the wind into a torque (rotational force), which propels an electric generator to create electricity.
Hydropower uses the force or energy of moving water to generate power. This power is called ‘hydroelectricity’.
