This started out to be a very very very very snarky take on why Bjorn Lomborg, Roger Jr. and assorted others are just dangerous when they go on about how coal electrification is needed to eliminate indoor pollution in Africa and Asia, but indoor pollution from cooking and heating using biomass or coal is a huge problem, killing many each year, and among many there is a dangerous naivety.
Further, this problem is no secret, and there is a considerable literature, easily found, but allow Eli a few moments to lay it out.
The first point is that the issue is not fuel, but ventilation. Many bunnies have, or have prior experience with wood stoves and the older amongst us with coal stoves. While there are issues with external air pollution, a good chimney moves the problem out of the house. Of course, if your house is a hut or less, a good chimney is well beyond the cost of your house.
The second point is that the poor will always use the cheapest fuel, that is why they are called the poor, so substituting a more expensive fuel such as LPG or natural gas and certainly not fossil fuel generated electricity simply does not work. It has been tried. Further, in poor places, an entire infrastructure has been developed to provide biomass fuel of all types, if you forbid burning of biomass, many people who were making a bare living providing the fuel no longer have an income.
The third point is that a better, more efficient stove has value, the value is in lower pollution because the burning is more efficient, less fuel needed, e.g. less deforestation, etc., but the problem, of course is that better stoves are more expensive and unfamiliar. There have been successes, but these involved subsidies for the stoves, creating local industries to manufacture the stoves, and careful attention that the stoves were not far removed from what people were used to cooking on so that there was no culture shock. Improved cookstoves designed in a laboratory for maximum efficiency and minimum pollution without consideration of convenience and how people cook simply are rejected even when handed out for nothing. Solar cookers run headlong into this problem.
OK? Eli will turn the snark machine on again, but do go do some reading. Here is a review article.
