By scaling up deployment of energy efficiency technologies, building energy codes can support significant energy cost savings, improved grid reliability, air quality improvements, and greenhouse gas emission reductions. (cleanenergysolutions.org)
These range from energy efficiency technologies for buildings, or industry sectors where currently the technology is largely absent, like in maritime shipping or on sustainable island nations. (climateactionprogramme.org)
One lesson from the past forty years is that energy efficiency technologies benefit from R&D just as their supply - side counterparts do. (dotearth.blogs.nytimes.com)
