Interview with Shawn Naylor, Hydrogeologist, Solution #42 Heat Pumps (Geothermal)

The building sector worldwide uses approximately 32 percent of all energy generated; more than one-third of that is for heating and cooling. Maximum efficiency in heating and cooling could cut energy use by 30 to 40 percent.

The means to increase efficiency are at hand, and one technology stands out from the rest: heat pumps…

The source or sink of heat can be the ground, air, or water.

Project Drawdown – #42 Heat Pumps
Interview with Shawn Naylor, an hydrologist with the Indiana Geological & Water Survey on August 29th, 2019.


Project Drawdown is the most comprehensive plan ever proposed to reverse global warming. An international coalition of more than 200 researchers and other experts identified and modeled the 100 most substantive, already existing solutions for addressing global warming.

Shawn is one of Indiana’s foremost experts in both geothermal energy as well as heat pumps with a ground sink.
