With a virtual forehead slap, energy expert Michael Barnard, writing in CleanTechnica, invites us to look for the energy (and greenhouse gas) savings we so desperately need from the demand side rather than the supply side. In particular, he walks us through data and calculations showing that just one intervention -- using heat pumps to do most of our domestic, commercial and industrial heating and cooling -- could cut U.S. energy requirements by a stunning 50%.
Looking at cutting energy demand rather than trying to reduce primary energy production makes a huge difference in our assessment of what's possible, what's economically and technically feasible, and what we can do in the few decades we have left to stabilize the climate.
