Energy efficiency has come a long way. From the energy crises of the 1970s, it has grown and evolved to become an integral part of our energy landscape.
Energy efficiency has done much to improve our economy and environment, but more can be done. Most states have policies and programs in place that seek to achieve even higher energy savings. A number of national efforts similarly aim to increase energy efficiency to achieve economic and environmental benefits. A clear example is the EPA Clean Power Plan, which seeks to achieve significant reductions in carbon emissions. Energy efficiency can play a major role in achieving emissions reductions under the plan.
After all this success with energy efficiency, what’s left? Has the limit of energy efficiency been reached? This is a particularly vexing question for utilities and organizations that run efficiency programs for utility customers, and this is the subject of ACEEE’s latest report. For full report see here.
