Because energy savings represent the absence of energy use, it is impossible to directly measure energy efficiency impacts; the credibility of the reported data is only as sound as the measurement and verification (M&V) processes, methodologies, and data that are used. Using the three C’s—Certainty, Credibility, and Consistency—builds confidence in the M&V processes, methodologies, and protocols, and thus in the reported results.
The efficiency of combined heat and power (CHP) to reduce emissions and fuel consumption is very often underestimated.
Finally… energy efficiency may be getting the respect it deserves. But that respect and a renewed focus come with a bit of rebranding.
