"The rest of the world..." signed onto the Pee Accord because Obama promised them a "carbon credit check" These checks amounted to $1T from the U.S. The money in 90% of these countries will go to the autocrats who will keep it for themselves. Wind and Solar are the most expensive energy on the planet. Poor countries can never afford it, anyway. Plus, science wise, the storage battery is 50years behind ,  meaning that after dark there will be no electricity(yes winds decline in the eve, too). The best energy system for a modern country is ALL forms with Tech invested in clean burning etc.
P.S. China, India and Russia did not agree to stop anything so that their economies will NOT be damaged. And Germany closed its Nuclear Power(cleanest E system) and is now forced to use coal to make up for the loss!
