At its core, the green movement is about reducing energy consumption, which in industry parlance is also known as demand-side energy management.
Successful demand-side management involves making energy consumers aware of how much energy they use on a regular basis, and then offering them effective ways of curtailing that use. The most effective methods for curtailing energy use are those that are easy for users to adapt.
