It is going to be cheaper for poor countries to go directly to renewables. There is no law that says that you need to pollute to become wealthy. The pollute-y kinda tech was just more cost-effective in the past.
A third of the world still burns wood for fuel. One of the most effective things we can do to curb emissions is get them using coal instead. Renewables are not in the immediate future for much of the world.
Burning wood releases more ghg per unit of energy than coal. We're not talking about biomass pellets in efficient furnaces, but actual wood in a stove. The fact that a tree can grow back in 20 years and alter the equation doesn't help us at all right now. Leaving the trees standing and instead burning coal will result in a decrease of emissions.

Coal plants are the cheapest way to produce electricity. And no, solar which operates at a fraction of installed capacity and is useless for large periods of time is not a cheaper alternative.
