The Philippines Geothermal Energy Potential, Explained

Scientific Concepts and Discoveries:

• Geothermal Energy as a Reliable Source: Geothermal Energy has been a consistent and reliable energy source due to decreasing production costs, with modern plants costing around 5 cents per kilowatt-hour.
• Sustainability and Renewability: Geothermal Energy is sustainable and renewable because the heat extracted is minimal compared to the Earth's vast heat content.
• Global Geothermal Production: Only a few countries have significant geothermal resources, notably the United States, Indonesia, and the Philippines, which together produce about 60% of the world's Geothermal Energy.
• Production Capacities (2020):
  • United States: 3.7 Gigawatts
  • Indonesia: 2.1 Gigawatts
  • Philippines: 1.9 Gigawatts
• Philippines’ Geothermal Energy History and Potential:
  • Known since the 1980s for abundant geothermal resources.
  • By 2005, Geothermal Energy accounted for over 16% of the country's electricity generation from just six geothermal fields.
  • Some power plants built in the 1970s are still operational, supplying energy to tens of thousands annually.
  • Predicted growth to 2.1 Gigawatts by 2025.
  • According to the Philippines Energy Plan (2016-2030), geothermal capacity is expected to increase by 1.3 Gigawatts by 2030, on top of the 1.9 Gigawatts in 2020.
• Future Outlook: Advances in technology are expected to improve the ability to harness Geothermal Energy more effectively, expanding its role in the nation’s energy mix.
