In this case, where I have something of a background in renewables and energy sources, I can just say that society has been built on putting 1 unit of energy in, and getting 100 units out, to spend.
This was mining coal and oil.
It was virtually free, unlimited energy we could do whatever we wanted with, and we did.
World population boomed, we built more per year than was ever built in the two thousand years prior, everything we have now at the price we have now is because you can take 1 barrel of oil, pour it into a machine, and like magic you'll magically have 100 new barrels of oil.
Solar doesn't do this.
Let's say you spend one barrel of oil, and get one solar panel. You then leave that solar panel sitting in a field for 20 years, and you then get two, shiny, new solar panels you can use for another twenty years.
After 100 years, you now have 32 Solar panels!
YAY!
Or, you could have used that barrel of oil, and the next day, gotten 100 more barrels.
The solar at best gives you one spare panel every 20 years. Either take it and use its energy elsewhere, or double up so you have 4 panels in 40 years.
This is all with no energy to spare, mind you. A solar panel sitting for 20 years only produces enough energy to make two solar panels.
Wind isn't much better, thermal barely gets you 1/1 replacement, the only option that could actually replace coal and oil is nuclear, which gets you 1000x ROI, which would save us, but politicians are too fucking dumb to build them and keep decommissioning all the plants without replacing anything.
The one thing that could save us, with the lowest rate of deaths of any other power source, sometimes by a factor of tens of thousands, and we ignored it because of hippies.
