Study Notes
Renewable Energy Sources
- Renewable energy sources are energy sources capable of replenishment within a human timeframe.
Geothermal Energy
- Geothermal energy is natural heat from the Earth's interior.
- The Philippines ranks third globally in geothermal capacity.
- Arturo Alcaraz is known as the "Father of Philippine Geothermal Development."
- In 2022, 13.4% of the Philippines' electricity came from geothermal energy.
- Makban GP is a 458.53 MW geothermal power plant located in Luzon.
- Unified Leyte is the largest geothermal power plant in the Visayas.
- A 108.48 MW geothermal power plant is located in North Cotabato, Mindanao.
- The total geothermal capacity in the Philippines is 1,951.8 MW.
- Indonesia is the second-largest geothermal energy producer globally.
Geothermal Power Plant Types
- Dry Steam Plants: Use naturally occurring steam.
- Flash Cycle Plants: Operate at higher temperatures than dry steam plants. Use steam from boiling water.
- Binary Cycle Plants: Use a secondary fluid with a low boiling point.
Geothermal Energy Impact
- Geothermal energy is not a high greenhouse gas emitter.
- Geothermal energy development has high initial costs.
- The Philippines' first geothermal power plant operated in 1967.
- Geothermal feasibility requires a heat source, permeability, water supply, but not necessarily shallow depth.
Geothermal Power Plants in the Philippines
- Unified Leyte - 610.18 MW capacity.
- Bacon Manito – Located in Sorsogon/Albay.
- Palinpinon – 192.5 MW.
- Maibarara – Located in Batangas.
- Mindanao North Cotabato– 108.48 MW.
Geothermal and Sustainable Development Goals
- Geothermal energy supports climate action (SDG 13) and affordable and clean energy (SDG 7).
Geothermal Feasibility
- Geothermal feasibility criteria include a heat source, permeability, and water supply.
Additional Information
- Binary cycle plants are not most common for high-temperature geothermal systems.
- Geothermal energy contributes to economic growth.
- All geothermal power plants do not operate at the same efficiency.
- Shallow vs deep geothermal drilling: Not all geothermal projects require shallow drilling.
- The percentage of global geothermal capacity accounted for by the Philippines is 12%.
- The most common type of geothermal plant globally is the flash cycle plant.
- The primary fluid used in flash cycle plants is steam from boiling water, not oil or a secondary fluid.
- Geothermal energy reduces the environment's reliance on greenhouse gases as a source of energy, not the other way around.
- Tiwi geothermal plant is located in Luzon, not in other areas.
