Geothermal Schools in Iowa
Something good is happening in Iowa schools that has probably not been given enough notice in the press. It's a "green" revolution, that has nothing to do with school books, class size, or grade point averages. It is hidden in school basements but it also shows up in the principal's office -- as a positive contribution to the school's budget.
What is "it"? It is geothermal heating and cooling systems that are replacing old boiler-room furnaces at a surprising rate.
Geothermal is becoming popular in schools because it is a free and totally renewable source of energy -- captured by putting pipes in the earth beneath baseball fields or football tracks.
Living in Iowa looks into this trend and visits a school in Columbus Junction that replaced its outmoded and somewhat cranky boiler-room system with geothermal in the summer of 2005.
