Yes, and every order of magnitude is worth it at this point.
We do have an infinite source of power. It is called the sun.
There are huge leaps forward right now in solar, price and efficiencies; and the problem of storing the suns energy for night time and down time has been solved too.
There are now many different ways to collect the solar energy through solar windows, and even a kind of paint that can be used to collect the energy, which means you could turn your entire house into a power generator.
Granted these technologies are new, and need to be perfected, and implemented. But It is now cheaper to generate electricity with wind and solar than with coal.
There is also more than just wind and solar coming online in the future.
Fusion power is actually a thing now. and there has been small scale experiments in creating electricity with fusion, but that will probably be coming online in the next 20 years. There is a potential tidal ocean generator too, thermal generators, and water batteries.
So It is only a matter of time for renewables to take over. until then we need the safe network for more orders of magnitude.
