I certainly agree that far to less is done.
Humans generally don't like to give gained comforts voluntarily back, especially not if they otherwise had to pay even more for perhaps less luxury.
In the 70's, when we had the oil crisis, everyone was scared silly about the probale lost of oil as energy: we had car-free Sundays and all those enrgy saving stuff started.
Nowadays, we've got energy-saving-bulbs all over the place, fridges and deep freezers have got three A's with thre stars in energy saving, ... but we e.g. still built houses like in those days. (Only a rather low percentage is built completely as a energy-saving-house.)
That would be an aim, for instance.
Or look at the proposal of our prime enrgy consumption:
In 2020 we Germans will still use 38% of our energy from oil - even more than today.
