As institutional campuses are exploring ways to draw down greenhouse gas emissions, one of the largest sources of ongoing emissions is heat via fossil fuels. Many campuses use steam, a century-old technology that relies on coal, natural gas, or nuclear energy to heat water into steam that is piped through buildings through radiators. But technology has greatly advanced to the point of requiring nearly ambient-temperature water to heat our buildings. Moving toward climate neutral means moving away from these old technologies, specifically to electricity-powered systems that can be fueled by renewable sources.
