Coal is the easiest to install in a poor or developing country that has little existing infrastructure. It is the easiest to transport – by ship, rail and truck. It is straightforward to build a coal-fired power plant. And to operate it.
In the developing world, large-scale renewables are not effective since there is no baseload to support them, no back-up sources to load-follow the intermittency, and no extensive high-voltage distribution system
Consider this was from the same source. It is contradictory and focused on the paradigm of centralized energy generation .
I set up and run my own power generation.
In the backyard with little more than basic tools like a hand saw and a screwdriver and the knowledge of how to wire a circuit..
it supply's my power 100% and needs no back up or distribution net work.
The total cost was less than the cost of running a cable 350m from the road to my house.
Distributed solar is cheap because you dont need to construct and maintain a grid or supply fuel.
What do the poor need? aircon, spapools?
Nope 1st light, 2nd fridge to keep food, 3rd cooking .
1kw of panels will supply enough power for a family for thirty or more years .
The required technology is cheap and getting cheaper.
Big energy, Centralized generation is steam powered 1800's tech.
Get with this century.
