We're on track on a big part of Europe being energy-restricted this winter, so at least right now there's not an abundance of energy even for the current needs of the first world, much less for those who cannot pay much and would need not the same amount but growth.
In the long term many things are possible, but right now we don't have enough energy, and "if we deployed new renewables" is not an argument - we already are deploying new renewables pretty much as fast as we can, and even if we would deploy them twice as fast, it will still take quite some time to get to where renewables can create all the energy we need - especially if look at the market share of renewables in total energy which includes not only electricity but also heating and transportation.
