Depends a bit on what you mean by conservation. If you mean "getting more energy from a unit of oil or gas", then it means that energy has greater productivity. Productivity compounds growth.
If by conservation you mean "avoid using a unit of oil or gas today in order to use it tomorrow", then that makes little sense economically. The only economic value of energy is using it to produce things that have even greater value. If you can use a unit of oil to produce something worth $10 today, there is little point in deferring the production of that $10 until tomorrow.
In fact, since economic growth is subject to compounding, delaying use could actually reduce the present value of the oil or gas.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
