Those are fair objections. Concerns I have myself, but the counterproposals seem scientifically unfounded to me: picking certain technologies (and inevitably companies and industries) and deigning them "the green future" based on our still early developments in science and engineering.

Worse, people are calling people with concerns about subsidizing, say, certain battery companies (at the expense of alternative approaches and competing battery companies) as "global warming skeptics" and "anti-science". As if subsidizing particular avenues of R&D is a scientifically objective question.
