Energy from the Earth – How does it work?
Posted August 1, 2022, Length: 22:23
Because temperatures below the surface of the earth are relatively constant year around, the earth can be used as a heat sink or source to cool or heat buildings, offering an energy source that is not only carbon-free, but is also constant. How does this work? Where and how can we use this seemingly free energy source?
To answer these questions, we talk with Alessandro Rotta Loria, Assistant Professor of Civil & Environmental Engineering at Northwestern University, who studies the connections between geomechanics, energy, and environmental sustainability.
The Infrastructure Show is sponsored by Northwestern University.
