Officials and dozens of residents in Holland, Mich., are working to implement a Community Energy Plan after the city began approving work groups for the effort in August 2012. The CEP, would, among many other things, expand the snowmelt district and channel waste heat to nearby commercial buildings. The 40-year strategy calls for cutting the community’s energy consumption by up to 60 percent and moving HBPW to cheaper, cleaner natural gas and non-polluting wind and solar power.
