Using smarter technologies, more brains and less money to wring more work from less delivered energy--what energy experts call "end-use efficiency"--is the largest, cheapest, safest, cleanest, fastest, most diverse, least visible, least understood and most neglected way to provide energy services.

Secondly, when considering end-to-end efficiency, it is much less energy-intensive to heat water by direct use of natural gas on-site, rather than by using that natural gas to first make electricity that is used to heat water because of the large conversion losses at power plants.

Greenpeace asks companies to measure and reduce their greenhouse gas emissions throughout the life cycle of their products: supply chain, manufacturing, distribution, customer use, and end-of-life, using a combination of energy efficiency, renewable energy, and energy policy advocacy.
