Reasons:
1) Supply of LPG is not always assured, so kerosene and electricity is used when there is not adequate supply of LPG.
2) Electricity supply is not predictable and power cuts are common. In this regards, LPG, charcoal, kerosene are used on standby depending on the preference of the user.
3) There are some cultural foods that requires one to have multiple types of stoves, and therefore fuels
4) Fuels might be easy and cheap to get but prices of equipment (eg gas cookers, electric cookers) is expensive. This has a bearing on lpg and electric cookers
5) Charcoal is so versatile that it is not only used for cooking or heating but also for house warming
6) Electricity cost is very high relative to other fuels and therefore, when cooking hard foods that take long to cook, and when boiling water, charcoal is preferred even by the ones endowed with resources.
So as Rob Bailis mentioned, the Mexican case is very close
