Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the global geothermal power capacity (2019)?13,900 megawatts
2. What is the cost of new geothermal power (2021 estimate)?$0.05 per kilowatt-hour
3. Where can we find good places for geothermal power?Good geothermal places are usually near tectonic plate boundaries, where volcanoes and fault lines bring hot rock closer to the surface.
4. How did people use geothermal heat before electricity?People in ancient times used hot springs for bathing, and the Romans built aqueducts and baths that used geothermal water for heating.

Tectonic Plate Boundaries: Areas where the Earth's large crustal plates meet, often associated with geological activity.
Binary Cycle Power Plant: A type of geothermal power plant that uses a secondary fluid to generate electricity from lower-temperature geothermal water.
Enhanced Geothermal Systems (EGS): Technologies that create artificial geothermal reservoirs in hot, dry rock formations.
