Paris digs deep to harness earth's energy

Paris is utilizing geothermal energy by digging 2 kilometers deep to heat 12,000 homes. This renewable energy source is environmentally friendly and cost-competitive with gas. Since 2005, geothermal projects have increased due to rising fossil fuel costs and a policy backed by Paris's City Hall. Paris has various renewable resources, including geothermal, solar, wind, and biomass. Buildings connected to the district heating grid, like French radio, have used geothermal energy for decades. The city aims to expand this to more neighborhoods.
