Still there is going to be energy lost for very little in return. We need to go the other direction; less machines, less IP addresses, less energy, less complexity, less code, etc.
The only thing we need more of is cores and we can't have that because memory is too slow.
I think this post shows that indeed small things adds up. Energy might rise by using HTTP/2, but that's not the concerns of OP, they want to reduce their cost, not their energy footprint.
I think you are going to have a rough time if you separate energy and money like that. The only reason the dollar is worth anything is because of coal, oil, gas and nuclear.
What do you think happens to the value of the dollar when the physical supply of energy becomes unstable in the coming years?
Money is energy because debt needs energy to either have been spent in the past or energy being promised to be spent in the future.
The proportion between these is what makes debt money trustworthy or not. When the states around the world privatizes houses that is old energy (so far since the energy to heat the house is marginal compared to building it), but when the stock market goes up that is a promise for new energy.
Globally all money for old energy is saturated (negative interest rates) and now all liquidity is being injected into the stock market that promises that the future will be rich with energy.
The stock market (and all companies) is a promise to spend energy we don't have.
The only energy that is added to earth is sunlight, the only way to capture that energy are trees and plants.
All jobs are now meaningless because of the energy that we are wasting. And people now depend on wasting energy to have a job.
Do you see why energy is more important than money?
