Natural sources of energy

Wind Turbines

• A wind turbine is a popular name for a device that converts kinetic energy from the wind into electrical power. Technically there is no turbine used in the design but the term appears to have migrated from parallel hydroelectric technology.

Solar Panels

• Solar panel refers either to a photovoltaics module, a solar hot water panel, or to a set of solar photovoltaics modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

Hydropower

• Hydropower or water power is power derived from the energy of falling water or running water, which may be harnessed for useful purposes. Since ancient times, hydropower from many kinds of watermills has been used as arenewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills,trip hammers, dock cranes, domestic lifts, and ore mills. A trompe, which produces compressed air from falling water, is sometimes used to power other machinery at a distance.

Biomass

• Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-based materials which are specifically called lignocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.

Electronic Vehicles

• An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration.
