People are going to do things differently because it is to their advantage. No one wants the choking pollution that China and India have.  All places understand the advantages of a zero fuel cost economy but many countries have not had enough capital to develop the old style energy distribution system. Given a capital start people will use the new energy systems and likely get them from the source of funding.  If China funds them then they will be loyal customer for Chinese products and if the US funds them we will have export customers.
All reductions in global pollution are useful.  The Paris agreement is not enough but it is an important step.
