As someone who comes from a developing country, it will be quite hard for us to get into the level of the rest of the globe because of the regulations which are being put in place at the moment. the only thing which will change the game is the advancement of solar panels and other green energy sources. this will be good in the long term.
That won't work. To move a region of the developing world forward requires power infrastructure sufficient to support modern industry, and this means coal power plants, then efficient electrical distribution to business centers.
It could also mean nuclear power, but that's not available for many regions. Hopefully that will change with the new designs for thorium reactors.
