Geothermal heating plants
Geothermal energy is free and renewable. Several techniques exist to use geothermal energy, the two main techniques being water-source (left) and ground-source (right) heat pumps :
A rapidly growing market
By 2050, the development of geothermal power could reach about 5% of global world demand for heating. This is the conclusion of a report published in 2011 by the IPCC (Intergovernmental Panel on Climate Change). However, in all scenarios envisaged by the IPCC, “geothermal energy is below the limits of its technical potential”.
Geothermal energy is already the second source of renewable energy for heat in France and the “Grenelle de l’Environment” has set ambitious goals for 2020 : to increase the production of the energy produced from geothermal energy by 6 . It is a contribution of 1.9 Mtoe, equivalent to 50% of the total production expected from wind turbines in 2020.
It is estimated that in the Paris region, the number of homes heated with geothermal energy could rise from 150,000 in 2011 to 180,000 units in 2013 and 500,000 in 2020. These developments imply important investments in energy infrastructure for the player in the geothermal industry.
