Today's Big I is on geothermal energy. Its the idea that you can heat and cool your home by pumping water through a closed loop system into the Earth. Basically, just 10 feet down below the surface the ground is a balmy 50 to 60 degrees year round. So you can pump hot water down to cool it or cool water down to heat it. It's a hefty initial investment, but it can be recovered by a 30% uncapped federal tax credit and with a 50% cut in your energy bills.
