What is renewable energy?
Renewable energy is energy which can be obtained from natural resources that can be continuously renewed.
Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun (such as thermal, photo-chemical, and photoelectric), indirectly from the sun (such as wind, hydro-power, and photosynthetic energy kept in biomass), or from other natural movements and mechanisms of the environment (such as tidal and geothermal energy). Renewable energy does not include energy resources derived from nonrenewable fuel sources, waste products from fossil sources, or waste items from inorganic sources.
Types of renewable energy:
Solar energy is energy which is created from sunshine, or heat from the sun. The solar energy is recorded when energy from the sun is converted into electrical energy or used to heat air, water, or other fluids.
Wind energy is created by transforming wind currents into other types of energy using wind turbines. Winds are generated by complicated systems involving the rotation of the Earth, the heat capability of the sun, the cooling result of the oceans and polar ice caps, temperature level gradients in between land and sea, and the physical impacts of mountains and other obstacles.
Hydropower is a renewable source of energy which utilizes the force or energy of moving water to create power.
This power, or ‘hydroelectricity’, is created when falling water is funnelled through water turbines.
