They've dramatically increased the awareness of energy use and energy efficiency, with large companies running high-profile lasting programs. As a result, power consumption never rebounded despite GDP growth, as energy conscious practices became ingrained. More importantly, there is huge potential for technical measures to reduce energy usage even further - a resource that has only begun to be tapped into."
