What is the concept of district energy?

    The concept of district energy dates back all the way to Ancient Rome when it was developed as a way to bring hot water to structures.  The technology was revamped in the 19th century in Europe.  Today, district energy systems involve the production of cold water, hot water or steam at a central plant and then the energy is pumped through underground pipes as a way to heat or cool multiple buildings.  Once the water is used by the individual structures for its heating and cooling needs, it recirculated back to the central plant to be reused.  Current companies also use other resources such as natural gas, oil, and wood ships to fuel the system.  Since this community energy system is closed-loop it utilizes renewable energy sources, reduces waste, and increases efficiency.
