'unless electric beats it for baseload' seems like an error; perhaps you meant 'unless renewables beat it for baseload'
the cheaper/useful/constrained trichotomy seems like a similar error; supply constraints manifest as higher prices, and the usefulness of a fairly fungible commodity like energy is entirely relative to its price
pv with batteries is already cheaper than fossil-fuel sources in much of the world, and largely as a result, fossil-fuel consumption for electrical generation is already slowly dropping in much of the world; this has already resulted in a rash of bankruptcies of coal companies
overall fossil-fuel consumption is not dropping, but will be within a few years
