Sharing Enefirst Plus knowledge on the Energy Efficiency First principle

The purpose of the Energy Efficiency First (EE1st) is to give priority to demand-side resources, such as energy efficiency and demand-response, when they are more cost effective from a societal perspective than supply-side energy resources in energy planning, investment, and policy. However, the previous evaluations of the National Energy and Climate Plan (NECP) and similar projects, such as ENEFIRST shows that implementing the EE1st is easier said than done.
