The current energy discourse frequently differentiates among "modern" and "traditional" fuels, assuming that there is a linkage between the income level of households and their fuel choice; this is generally referred to as the "energy ladder hypothesis". Petroleum products such as kerosene and LPG as well as electricity are considered to be modern fuels at the top of the energy ladder whereas traditional fuels such as woodfuels and agricultural waste end up at the bottom. Charcoal is often considered as a transition fuel, being that it is a marketable commodity with a higher level of convenience than traditional fuels.
