Here is an idea. Pick a city of 500,000 people. Turn the entire city green. Every product that will be part of the city cannot contain petroleum products. Infrastructure and transportation has to run on renewable energy. This must be done within two years of adopting the plan.
The city will be monitored for five years. This includes “climate.” If after five years the climate in the city changes, a city of 1,000,000 people will now be tried. And on and on.
I say the District of Columbia is a perfect test city.
But, but what about all those plastic water bottles?
As long as I don’t have to pay one damned dime on such a load, go for it. This will require enormous gov’mt oversight — and skimming. Doomed to failure. I live in such a regime’ in CaCaLand, nothing works.
