Then we just move the problem. Why should we do something that's going to take longer and use more labor? Especially skilled labor.
Money is an imperfect proxy for the underlying resources in many ways, but it about lines up in this case. To force the issue, there would have to be a compelling reason beyond straight money.
That reason ain't getting to 100% clean energy in a short time. There is another: building plants to use up existing waste rather than burying it.
