There is nothing the US can really do without going to war with India and China and that won't probably work, either. The US may think it lives in a bubble, but it does not. Greenhouse gases - China (29%), India 7%, USA 14%, Russia 5%. Studies say you have to reduce by 43% to stop global warming. Even if the USA got to net zero, which will never happen, you still are 29% off. Reduction of oil usage in the USA will increase use of oil in 3rd world countries as it becomes a cheap alternative. Then we will have to aks what are we going to do with all the toxic waste created by disposed of solar panels?
