We envision a future where Nuclear Power takes on a more active role in the Philippine energy mix. It will replace fossil fuels and will work with other clean energy sources. In our country, there are five major Renewables currently in use. These are:
- Hydropower – Hydropower plants capture the energy of falling or flowing water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.Hydroplants range in size from “micro-hydros” that power only a few homes to giant dams like the San Roque and Magat Dams that provide electricity for thousands of households.
- Geothermal – Geothermal energy utilizes the natural heat found below the Earth’s surface to produce steam. This steam is then harnessed to provide mechanical/ rotational energy to turbine blades with a shaft connected to an electric generator. This link provides an informational animated representation on how Geothermal power plants work:
- Biogas – Biogas technology works like coal plants in terms of burning fuel to produce heat in a boiler and convert water to steam. The steam is again utilized to turn turbines and activate generators for electric production. Though feedstock for Biogas power plants is also burned (examples are bagasse and livestock manure), it has been proven that they substantially have lower harmful emissions than coal, gas, oil, or diesel.
- Wind – Without burning anything to produce heat and steam, gigantic propeller-like blades are set atop a tower to harness the kinetic power of wind. It’s a simple, emissions-free technology where the rotor of these blades is connected to a shaft that spins a generator to generate electricity. Countries with vast stretches of coastlines greatly benefit from this simple principle.
- Solar – Solar energy’s basic generating unit are solar panels. Solar panels are made up of photovoltaic (PV) cells which convert sunlight (or photos) into electrons of direct current (DC). These electrons flow out of the solar panel and into an inverter/ electric panel/ breaker box where DC is converted to the more useful alternating current (AC) to power and light our homes.
