Good point. Perhaps the poorest countries need some more appropriate means of producing the energy they use for warming their homes, cooking their food, increasing their agricultural production.
I don't thing they need anyone to do it for 'em - perhaps they just need for the technologically-advanced (richest) countries to show 'em how...
We could, but don't need to - but already in undeveloped areas people are eager to cook without having to gather fuel, and to improve their own neighborhoods. Increasing numbers are doing just that. :)
There's nothing wrong with using electricity to cook, but there are other ways - and, people being the inventive critters we are, we will find more ways still to fry our bacon...
