The experience with energy efficiency in IEA countries

Is energy efficiency as good as it sounds? Proponents of energy efficiency policies sometimes face difficult questions. For example, if more efficient heating, refrigeration or lighting appliances reduce the energy bills, do consumers tend to use them more, thus eroding the energy savings? Or are the energy planners basing their calculations on flawed assumptions, or on unrealistic discount rates? Do energy efficiency drives sometimes trigger perverse effects? These and many other searching questions are addressed and answered in a recent IEA Information Paper, The Experience with Energy Efficiency Policies and Programmes in IEA Countries: Learning from the Critics. The authors take a positive view and indicate lessons to be learned from past experience.

A good publication but partly not relevant since it is based on the idea that energy efficiency is a tradeable good. Energy efficiency is a characteristic embedded in goods that we use for other purposes (refrigeration, transportation, lighting etc.).

In resource analysis it is necessary to make the assumption that energy efficiency is equal and comparable to energy supply, but in marketing it fails since most people do not recognise the energy efficiency in its own right (and do not even care).

And finally cost-efficiency may not be the sufficient criteria for chosing energy efficiency prior to energy sypply. It may happen as the Danish Energy reseracher Joergen Noergaard said that: "It might not be cost-efficient to save the world but it could still be a good idea"!
