Study Notes
Geothermal Energy
- Geothermal energy is a type of renewable energy that harnesses the heat from the Earth's core to generate electricity.
History of Geothermal Heating
- Geothermal heating has been used for space heating for over 2,000 years, with ancient civilizations utilizing hot springs and geothermal resources for warmth and comfort.
Unique Characteristics of Geothermal Power
- Geothermal power is distinct from wind and solar energy because it is a baseload power source, meaning it can provide a consistent and reliable supply of electricity.
Geothermal Extraction Activities
- Most geothermal extraction activities occur in regions with significant tectonic plate activity, such as the Pacific Ring of Fire, where the Earth's crust is thinner and more permeable.
Cost of Geothermal Power Generation
- During the 1980s and 1990s, the cost of generating geothermal power decreased significantly, making it a more competitive and viable alternative to fossil fuels.
