I would have expected that this can only be possible through economic downturn. Sure, the more efficient light bulbs can slightly flatten an ever rising graph, but we should not have any illusion that humanity will even use less energy than yesterday. That would only happen if a severe crisis of some form hits us.

And sure, if steelworks and chemistry is moved abroad, the country will use less energy on the whole. But then you have to calculate the indirect usage through imported products as well to have an honest "energy requirement" value for a region or country.

Not saying you can skip efficient light bulbs, but we need to stay realistic about future energy requirements.
