Transportation and healthcare are extremely profitable things. The question is profit for whom, and who pays. If we are talking about building a zero-carbon energy system, we should be talking about the lowest cost method of doing that, over times, taking into account externalities. All the modeling of zero carbon energy systems finds that massive amounts of solar and wind are the backbone of energy generation. The amount of nuclear varies based on cost assumptions, and in particular if they use current battery costs and if they model the ever decreasing battery costs, but nuclear plays a very small role in the lowest cost zero-carbon grids of the future. A smaller role than it does today.
