Tidal energy- Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity.
River energy - The immense amounts of energy available from river, tide, and ocean currents are going unused. The helical turbine now makes it efficient and practical to capture energy from flowing water.
Solar energy - Energy from the sun, solar energy, is harvested in two methods. Semiconductor technology called Photo-Voltaic (PV) converts light energy into electricity. Thermal energy from the sun is harvested through heat absorption. Both types of captured energy can be used immediately or stored for later use.
