This is the fountain in front of Boise City Hall. It runs year-round, even in the icy-cold winter. It uses geothermal water, although, I'm sure not so much in the summer because we put our hands in it and it felt cool. A geothermal aquifer runs under Boise and the naturally-hot water is used to heat several buildings, including some of the Capitol. Congress is looking at giving Boise some money to expand geothermal use, including to heat buildings at Boise State University. While the water itself is "free" from the earth, it does take electricity to pump it up, and then pump it back into the aquifer after it's been "used."
