Iceland's Geothermal Energy System

Iceland has transformed its energy system from reliance on oil and coal to using geothermal energy, thanks to its location on the Mid-Atlantic Ridge. This shift has allowed Iceland to harness the earth's heat for heating homes and generating electricity. The process involves drilling for hot water using oil industry technology, which is then distributed to homes in Reykjavik. This system is efficient, low-maintenance, and environmentally friendly, producing no CO2 emissions. The video explores how Iceland's unique geological position has enabled this sustainable energy transformation.

What was the primary energy source for Iceland before the shift to geothermal energy?

• Solar energy

• Wind energy

• Oil and coal

• Nuclear energy

What percentage of Iceland's energy came from oil and coal when the narrator was a child?

• Over 50%

• Over 60%

• Over 70%

• Over 80%

What natural feature allows Iceland to access geothermal energy?

• The Andes Mountains

• The mid-Atlantic ridge
