Sure, but please also recognize that the only reason we've gotten to renewables being cheaper is through massive subsidies. Solar has gotten there from economies of scale and technological innovation, which has been driven by government R&D, grants, and also massive subsidies.

But also keep in mind that money as the sole motivator for the market is a sword that cuts both ways. If two competitors A and B are in the same market or are producing the same product, and company A uses any one of a number of environmental cheats, like fossil-fuels, then company A is going to out-compete B, make more profit, and eventually crowd out B.

The private sector will go for maximum profit and socialize the losses wherever it can. The role of the rest of society is to hold the line and not ruin the planet so that company A can make 5 extra cents a share.
