What is energy sufficiency? | ENGIE
Energy sufficiency refers to the deliberate and structured reduction of energy consumption. In addition to a decrease, it influences uses and pushes for a change in behaviour, both on an individual and collective level. It aims to reduce demand, and therefore reduce the strain on renewable sources. For an individual, this may imply …
