Imagine there's no growth. Why adopt solar power then, and who's going to pay for it since there'd be no investment capital? Nope, just run those coal burners forever. No need to upgrade if there's no growth.
It's fallacious to argue that because there's no net growth in some economic indicator, say 'GDP', that there can't be growth in specific sectors.
Secondly, growth is not a measure of demand, especially as demand shifts. People value having clean skies, and breathable air. And there is also a obvious value in 'not having to dig in mines for your energy'. Depending on how you measure your economy (let's say we unbeknownst to us give a higher weight to miners who dig underground vs. laborers panel assembly factories in our metric), 'upgrading' to solar could incur a 'contraction' instead of 'growth'.
