Let's look at what happened until now...
It's some years that the green economy is being prepared. They started telling us that climate will change and oil will finish. "Efficiency" sometimes has become a good word to start selling new products.
I'm scared about oil finishing, and pollution, but I'm not confident the current way we're facing energy problem is the right one. I think this is business, and a big one ("green" economy, but "green" is maybe the color of $, not of chlorofyl).
If the intention was to solve the problem, or to reduce it, they won't have pushed wasting, as they've done. For example, some of the incentives on solar and wind that we pay and will pay for many years (at least here in Europe) bring the message "waste as much as you can, since you produce with renewable energy". This cannot be the way!
Another thing that seems ridiculous is that we are all concentrated on electrical power. The real fact is that transportation, industrial and home heating are the most consuming activities, but little effort has been done for that. For example, if photovoltaic had to be incentivated, I'd have put the constraint of using heat pumps for heating, in houses.
I think that reducing consumes is the way to start. There is a know-how on reusing, saving things and making them on your own which is going to disappear. This has more to do with education (please correct me if I used the wrong word, I mean the one that is done inside families and in the society, not only into school) and economy.
