Let me guess: you don't live in Bangladesh. Where there are ~160 million people, and the country is just one big flood plain. Bangladesh already has the highest population density of any "big" country, and the sea is eating away at the land.
If $0.30/kWh is the real price of electricity after externalities have been added in, then so be it. Because the alternative is too awful to imagine.
Also you've forgotten to include in your calculations that Costa Ricans probably use a lot less electricity than Americans. Someone earning $6k.pa probably does not have AC, a huge refrigerator, etc.
If you pay $300/mo in air conditioning, then of course you won't have an air conditioner, assuming you earn 6k/yr
Also, if population density everywhere was the same as in Bangladesh, having green energy wouldn't have helped. It is far more "green" for many countries to force a one child policy than it is to switch to green energy.

No, they almost certainly don't. And they almost certainly suffer from the food-borne illness, heat stroke, and other health consequences associated with that fact (not even counting the general quality of life issues). Why do you think this is a good thing?
It's always amazing to me how people living a privileged Western lifestyle blithely condemn people in poor countries to a life of privation and misery, just so they can feel good.
