Indeed, the article notes that the mere suggestion that preferential rates for solar power could be dropped (rates that cost $5 per household in higher electricity bills), sent solar-power provider stock shares plummeting.
It is worth noting that companies that dig dirt holes and then fill them the next day could be profitable with high enough government subsidies. It doesn't mean supporting them is a good idea.
