Dear Ron Cecil reported that the cooking tasks are very clearly divided between the fuels. This holds in principle when there are multiple wood species available. So in principle, yes cost is a factor but it is also true that it is not always a dominating factor. If it was people would always choose the cheapest option which is not the case.
Cecil as part of the social science team will include costs but it is much larger than our opinion of course. Cecil and I both tend to think systemically meaning that we consider what would happen if everyone did it, or bought it, or tried to access it. Where are the limits in the system? Where does the market develop. The cost of trade fuels is largely limited by the cost of transport. Some things work in niches and any economy is full of them. The energy economy is no different of course. The big opportunity is for displacing kerosene with biomass. LPG is not available everywhere. This will probably require a serious look at controllability which is a major attraction for liquid and gas fuels. That and speed of ignition.
