Use Geothermal Energy for all government buildings new and old for prisons being built and retro fit all other prisons. At 7m in the ground the temp is a constant 50 degrees and at a little of 200 feet you get the heat from the earth, install this technology which is not new, just not widely used, there would not be a need for expensive heating and cooling systems that generate hefty bills and use precious fossil fuels. The Savings in the long term would greatly outweigh the costs.
