Study Notes
Natural Resources
- Natural resources support life and provide energy for both living organisms and machines.
- They are derived from sunlight or Earth's natural processes.
- Sunlight, the only external energy source, is essential for plants and algae (producers) to create food.
- Sunlight generates heat, influencing wind patterns, waves, and ocean currents.
- Electricity can be generated using harnessed sunlight.
Energy Sources
- The Philippines utilizes various energy sources, categorized into renewable and non-renewable.
- Main energy sources for Luzon, Visayas, and Mindanao vary in percentage distribution.
Geothermal Energy
- Geothermal energy originates from heat produced within the Earth, derived from Greek terms for "earth" and "heat."
- It is a renewable energy source, continuously produced from Earth's interior.
- Operational geothermal power plants include Tiwi Geothermal Plant and Maibarara Geothermal Plant, among others.
Hydroelectric Energy
- Hydroelectric power, or hydropower, is generated from the energy of falling or moving water.
- It is a reliable, mature, and competitive technology for electricity production.
- Types of hydropower plants include impounding dams and run-off-river types.
- Impounding dams supply energy during peak and off-peak hours, while run-off-river types vary based on watershed water volume.
- Kinetic energy from falling water is converted into electrical energy via turbines and generators.
- Notable operational hydroelectric power plants include Magat Hydroelectric Power Plant and Binga Dam.
Wind Energy
- Wind energy is a renewable resource, derived from solar energy, harnessed through wind turbines.
- Wind turbines convert wind's kinetic energy into mechanical power, which is then transformed into electricity.
- Significant wind energy facilities include Bangui Wind Farm and Caparispisan Wind Farm.
Solar Energy
- Solar energy is captured through technologies that convert sunlight into electrical energy via photovoltaic (PV) panels or mirrors.
- Photovoltaic cells directly convert sunlight into electricity without emitting carbon emissions.
- PV panels can be installed on rooftops for residential use, heating water, or storing energy in batteries.
- Operational solar power plants include Calatagan Solar Power Plant and a Solar Farm in Cadiz City.
Non-Renewable Energy
- Fossil fuel power plants are another energy source in the Philippines, with coal plants like Sual Power Plant providing significant energy output.
