> here is no a shortage of available energy we have a nuclear fusion reactor in the sky that provides more energy than we could ever use. We can only capture a small fraction of that energy; limited by land space and efficiency of the capture devices. In fact, we capture so little that we primarily rely upon the sun's energy that fell on past-earth to power our world today. To take this idea to the next step, even if we could capture and utilize every photon to fall upon our little sphere - given how much of our planet's ecology is based around using that very same energy - we'd destroy that same ecology. Sure, we might be able to convert CO2 to Oxygen more efficiently than plants, but it would still take energy. Sure, we can heat buildings and individuals, but that would also take energy. We could grow food in labs, but again, energy. There's a distinct cap on how much energy we can harvest from the sun. Using it to perform useless calculations because you want to work around government controls is wasteful.
