Obviously a socially equitable solution is desirable, but if the perfect plan is not on the horizon, perhaps a plan is better than no plan. Rather, scenarios of environmentally sustainable economic development require maturation and deployment of low-emission fuel sources. This technological shift will require nuclear power or renewables. The United States, the former Soviet Union and Japan have each experienced significant nuclear accidents, and physical and political barriers continue to stymie safe, long-term disposal of radioactive waste. In both the developed and developing world, the prospects remain dim for a nuclear fission regime free of meltdowns, thefts of radioactive material, weapons proliferation and unsolvable waste disposal issues.
Nuclear fusion remains out of reach.
Thus, hedging against environmental disaster while pursuing economic growth seems to require increased exploitation of renewable energy.
