Water seems more interesting than energy as a bound. If energy gets as cheap as breathable air is now due to some sort of long running series of changes and improvements cornering the market would be like trying to bag the whole atmosphere and then charge people for it. The cheapest things are the most impossible to corner. Not that I have any idea whether some sort of ability to do more with less can bound energy use below some arbitrary output threshold.
