And that's exactly what that big chunk of cash is supposed to be for - to help developing nations start out with cleaner power generation.

Right, but it does so by giving them money to spend on expensive stuff, which treats one of the symptoms instead of the root cause.

What I'd sooner advocate is to instead give that money to organizations working to make that expensive stuff actually cheap for everyone (or at least cheaper than the alternative of sticking with fossil fuels). That way, it's more economical for everyone (not just rich countries, and not just poor countries) to skip the fossil fuels stage of industrialization and jump straight to green energy everywhere.
