Heating Electrification: Policies to Drive Ground-Source Heat Pump Adoption

Executive Summary Ground-source heat pumps (GSHPs) are typically the most efficient form of heating and cooling for buildings. For every unit of electricity a GSHP system consumes, it produces roughly 3-4 units of equivalent heat (or cooling), thanks to the solar energy naturally stored underground. Because of these efficiencies, GSHPs can provide significant cost savings in the effort to ...

DYGEO: boosting support for geothermals to promote the use of this green energy

In 2018, ADEME and BRGM decided to focus on increasing the visibility of geothermal energy. First of all, this involves uniting the organisations that are promoting geothermal energy around an “advocacy campaign” for surface geothermal energy and then also of increasing the visibility of geothermal energy on the Internet. The need With the Multi-Year Energy Plan predicting that ...
