Harnessing Geothermal Energy: Exploring Iceland's Renewable Heat Source

The video explores geothermal energy, focusing on Iceland's use of this renewable resource. It explains how Earth's core and mantle generate heat, which can be harnessed through geothermal power plants and heat pumps. While geothermal energy is efficient and sustainable, its global use is limited by cost, location, and environmental concerns. New technologies are being developed to address these challenges and safely tap into Earth's heat.
