Does Energy Efficiency really reduce energy consumption?


Tim Harford

From a macro-economic point of view, is Energy Efficiency really a good thing? Or is it counter-productive? Some economist such as William Stanley Jevons used to think that “Energy Efficiency does not reduce energy consumption”. In this very thoughtful article, Tim Harford provides interesting insights to show that Energy Efficiency does reduce energy consumption.

Without trying to challenge this man of genius, Tim Harford, we can still have some doubts and not totally agree with him. Indeed, as someone commented in his blog: “Isn’t the reduction in the UK energy consumption mostly due to the fact that much industry has been displaced to other countries (China)? Wouldn’t you have to include “embodied” energy in your calculations when saying that reduced UK consumption per capita is a “mark against Khazzoom-Brookes”? How about internalizing external costs?”

The Conundrum - David OWEN

The book about Energy Efficiency all European leaders should read

There are people like Jean-Marc JANCOVICI or David OWEN, who try to rectify journalists mistakes, approximations and falsehood. In this very good book, David OWEN sets out to clarify concepts and to share some insightful rough estimates. While reading this book, you understand that the road to Hell is paved with good intentions, and often so-called Energy Efficiency solutions can be counter-productive.

Hybrid cars, fast trains, energy-efficient light bulbs, solar panels, carbon offsets… Forget everything you ever thought you knew about living green. The Conundrum is a mind-changing manifesto about the environment, efficiency and the real path to sustainability.
