Hm, well I see your point. Direct investment in companies is risky for everybody, governments and individuals.

But what else is there? How is government supposed to create the right conditions for a market solution? The solution was supposed to be carbon credits by making using polluting materials gradually more costly over time and thereby creating the conditions for clean(er) energy to be viable in the market. But that was rejected outright as a "tax."

Government as a member in the market is bad, we can agree there. But outside of direct investment, it gets politically difficult to change anything.
