What it is...

Community, or district, energy is thermal (heat) energy provided to a number of buildings in a community from a centralized plant through a closed loop pipeline distribution system.  Cooling can be provided in a similar manner during the summer.

Sources of the heat vary widely, including biomass, organic community waste, waste water heat recovery, lake water, bio-fuels from landfills or sewer systems, heat recovery from existing industrial processes, and natural gas.

The heat provided through the pipeline is transferred through heat exchangers in each of the buildings on the community energy system (CES).
