Děčín, once one of the most polluted cities in the Czech Republic, has shifted towards a future of clean energy through the use of geothermal technologies. Geothermal energy, which is harvested from an ancient body of hot water lying hundreds of feet underground, has helped reduce the city’s carbon footprint and has significantly improved air quality. More than 10,000 households and Aqua Park Děčín, a recreation complex, are heated using geothermal energy.
A power plant in remote southern Idaho generates electricity with water heated by the remnants of ancient volcanoes. Water is forced underground where it heats up. The accumulated heat is used to run turbines that generate electricity. Geothermal energy is a renewable resource than can be harnessed for the production of electricity 24 hours a day, year round, potentially for centuries without adding energy to the system.
