The deal is actually the opposite. America doesn't really need to do much to meet Obama's target. The natural market-driven growth of renewables will do it, so long as the GOP doesn't play pick the winners and losers by slapping regulations. (*cough* Kansas *cough*). It may well cost the US consumer $0. China, on the other hand, is deploying huge amounts of new energy, and will fundamentally need to shift their plan in order to have emissions peak in 2030. But they want to do it anyway, since -- pollution, and they will be at the bleeding edge of renewables technology with will own carbon by 2030. Heck, wind is already price parity with coal, and solar is dropping fast. See
Levelized cost of electricity by source. And I say all of this knowing that you cannot understand it, because you are a "skeptic" with the "truth". (Somehow not a contradiction -- but that's human nature for you.)
