WASHINGTON, Dec 16 (IPS) – Energy efficiency (EE) is often marketed as a tool to save energy and money. The oft-repeated mantra is doing “more with less”, namely producing more goods with less energy. But, as set out in a recent World Bank report (which I co-authored), EE can do something that is often much more important for developing countries: it can produce the additional goods and services needed to raise standards of living.
