Either we plan this Green New Deal out in great detail or we don’t plan. The cost of failure to plan, in a highly politicized environment, is the probable hijacking of much or all of the funding for irrelevant projects that happen to make various people richer. Can you pay that cost?
First, I bang the drum for specific large-scale displacements of fossil fuel use. Existing houses should be retrofitted to be (about 90% is my personal target right now) heated in winter by the sun, and solar-driven air conditioning needs development too.
I claim that non-freeway transit can be seriously inexpensive, that is, if “we” go out and develop it. By the way, who in heaven or on earth is “we” going to turn out to be? Some athletic scholarship kid at Yale?
We need R&D in agriculture-based sequestration, and we need to try to subsidize test-farmers (foresters,…) around the world to see if we’re actually sequestering the carbon in the soil that we want. Quality control counts.
The Arctic is melting down and we need to inhibit this meltdown or else the atmosphere definitely heads to about 1200 ppm of greenhouse gases. Does that sound to you like an acceptable thing to let happen? If your garage is on fire, do you just sit and watch your house catch fire too? (assuming that you’re not rich)
So, that’s the planning work. Where are the workers? If there are zero workers for this planning task, billions of people are going to starve in a surprisingly short time frame.
