Moving air, turns the blades of large windmills or generators to make electricity, or to pump water out of the ground. A high wind speed is needed to power wind generators effectively. While wind generators don’t produce any greenhouse gas emissions, they may cause vibrations, noise and visual pollution.
Biomass is material of plants and animals that can be used for energy.
Geothermal energy uses heat energy from beneath the surface of the earth.
Fast-flowing water released from dams in mountainous areas can turn water turbines to produce electricity.
Solar cells convert sunlight into electrical energy.
Electricity can be obtained by the flow of water through turbines in a dam as the tide rises and falls.
