You can have everyone work hard to reduce their energy usage. You can have tax-funded subsidies to motivate green supply increase despite targeting reduced demand. And, that's all lovely and great.

At the same time, you can have a voracious, highly mobile demand for the cheapest energy around. You know, the kind that solar and wind is supplying, but sometimes in mildly inconvenient locations. This does not actually reduce the supply for everyone else. It's not a zero-sum game. Supply follows demand. This horrendous cadre of buyers directly pay for increased production of cheap green energy that otherwise would not have been set up at all. Thus, ramping up equipment production and economy of scale. And, motivating the creation of supply that otherwise would have been too risky to invest in.
