Yes, there are a lot of mitigation strategies and your standard answer will certainly reduce atmospheric CO2, for the most part. Electrified mass transit infrastructure powered by something other than fossil fuels will work well where the population density is high. Nuclear power plants, once the bane of the environmentally sensitive, are once more touted. Hydro is a semi-evil, preventing facile fish fornication, gas is now bad because of fracking, biomass requires significant energy to harvest, solar is nice for the southwest US and hopefully no desert life forms will be disturbed by excess shadows, wind power is problematic as a baseload but could be used, geothermal has promise but is likely not going to be significant for a while. If we consider that nuclear plants would solve our problems with CO2 and simultaneously permit production of transportation fuels, we must ask why we aren't building them. One can design such plants to circumvent production of weapons grade materials, so that isn't the problem. There is a mountain that is designated as a safe storage area for wastes, but we aren't using it. In the US, permitting has made nuclear power plant construction practically impossible. The many layers of checklists and agencies to be satisfied [Federal, state and local] are certainly a holdup. If we would like to use our power infrastructure with centralized plants, the US should do what France has done. Approve a standard model power plant design; no more one-offs. We should go for 250-500MW modules that will allow for construction of any size plant in those increments. Licensing can be streamlined to have the Feds override all state and local laws. If a state or community decided not to accept a plant, they would pay an increasing premium for fossil power.
As has been mentioned previously with the LEEDS platinum building construction, the biggest bang for the buck will be conservation which would include LED lights, insulated buildings, fuel efficient vehicles, and others. Chargers and routers would turn off at the primary when not in use. AC would be a heat pump and underground heat reservoir. This last may be costly but as the only approved AC products, there will be no way to circumvent it. Invest in fans.
My "type" that has earned your contempt may not be what you assume it to be and may not have much to do with a "50 year delay." Maybe it is the many environmentalists who want what they want or those like you who are so demonstrably defocused as to be unable to come up with specific solutions that must accept some of the blame.
