Renewable energy is an energy that can be replenished and can not be depleted when used. Nature naturally replenished it like sunlight, wind, rain, waves or geothermal heat. Renewable energy includes solar, wind, hydroelectric, geothermal, ocean, hydrogen, and biomass.
Sun uses its sunlight to produce electricity. Photovoltaic or solar cells directly transform sunlight into electricity. It is the most common type of renewable energy since the energy from the sun never runs out. In addition to this, solar energy is certainly less polluting than fossil fuels. One example of a solar power plant in the Philippines is G.A. Philkor Multi Energy Corp. (GAPMEC).
Wind uses wind power to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator then converts the mechanical power into electricity. The 54MW Pililla Wind Farm is the second wind farm in the Philippines.
Hydroelectric energy harness the power of falling water to produce electricity. Turbines convert the kinetic energy of falling water into mechanical energy. Similar to wind farms, a generator converts mechanical energy into electricity. The most common hydroelectric power plant uses a dam to store water. Water released from the reservoir runs through a turbine, which finally activates the generator to produce electricity.
Similar to hydroelectric and wind farms, geothermal energy uses a turbine to convert kinetic into mechanical energy. However, steam from the inner part of the earth rotates the turbines. It then activates the generator that produces electricity.
Promises to utilize renewable energy are booming because innovations bring downs cost and people are looking forward to a cleaner future.
