Study Notes
- Lecture notes supplement class notes and encourage cross-referencing, answering questions, and reading extra materials.
- Considers the impact of human activities on Earth's life support systems beyond just population size or density.
- The IPAT model relates environmental impact to population, affluence (consumption), and technology.
- Energy is the capacity to perform work, with work defined as the transfer of energy.
- Modern society heavily relies on energy.
- 94% of Metro Manila's energy comes from eight power plants in Pangasinan, Zambales, Batangas, Quezon, and Mindoro.
Global Energy Consumption
- Non-renewable energy sources deplete faster than they can replenish within a human lifespan.
Non-Renewable Energy
- Coal is abundant with existing mines in the Philippines; however, combustion causes harmful emissions, leading to respiratory and cardiovascular diseases, systemic inflammation, and neurodegeneration.
- Oil reserves are abundant in the Middle East, Venezuela, Canada, and Russia.
- Crude oil requires refining to separate its components before its usage.
- Natural gas is the cleanest fossil fuel.
- The Philippines has natural gas deposits in the Malampaya Deep Water Gas-to-Power Project.
- Burning fossil fuels, particularly coal, petrol, and diesel, significantly contributes to airborne particulate matter (PM) and ground-level ozone, increasing global mortality and disease.
- Nuclear energy is produced by splitting radioactive elements, a process called fission.
Renewable Energy
- Wind power harnesses the movement of air molecules
- Wind farms are located in Nabas, Aklan, Pililia, Rizal, and Bangui, Ilocos Norte.
- Hydropower harnesses the power of moving water with tidal and hydroelectric power plants (dams).
- Geothermal energy harnesses heat from the Earth.
- The Philippines ranks as the third-largest producer of geothermal energy worldwide.
- Geothermal power plants include Makiling-Banahaw (Mak-Ban) in Laguna and Malitbog Geothermal Power Station in Leyte.
- Solar power mimics the ability of plants to harness sunlight.
- Biomass (plants, agricultural waste) can be converted into liquid biofuels like bioethanol and biodiesel for transportation.
- Sustainable Aviation Fuel (SAF) is made from waste oil, fat, organic municipal waste, and non-food crops, which can reduce CO2 emissions by 80%.
Relevant Laws
- RA 9153: Renewable Energy Act of 2008
- RA 9367: Biofuels Act
