Yet it is often overlooked. According to the International Energy Agency, doing more with less through greater energy efficiency is not only the cheapest, but also the largest clean energy opportunity readily available. Fully half of the carbon reductions required to achieve current climate goals could come from improved energy productivity. That is three times as much as the next largest resource in the list: renewables.
