"Don't get me wrong: all efforts to build and develop renewable energy and energy efficient technology are useful and very necessary. My point is that, by themselves, they will not yield any results. To make them work, we need to put an absolute limit to energy use. Imagine that the European Union or the US would decide that in 2020 we can only use as much energy (or electricity) as we do today. Interestingly, all other efforts suddenly make sense. If the share of renewable energy would rise, then the share of non-renewable energy would automatically fall. Energy efficient technology would be automatically transformed in energy savings, and not in extra applications or performance, as it happens now (the energy efficiency paradox)."
