In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
If you’re talking residential geothermal, that won’t generate electricity for your home. It can be used for HVAC and water heating though. It isn’t zero maintenance, and for most people it is pretty expensive (because they don’t have enough land to use the cheaper method for laying the pipes in the ground. Also, call it what it is - Ground-sourced heat pump. Average install price is $30k-$70k.
In many latitudes Air-sourced heat pumps are much much less expensive and perform nearly as well.
I’m hopeful to see cheap to purchase, install, and maintain Ground-sourced heat pump (residential Geothermal) but its not hear yet.
