22 enumerated until two-thirds of the total population are covered, subject to there being at least two combinations containing LPG. As expected, almost all households using LPG in these top choices also used electricity. Lesotho was one exception where the third most common combination was LPG and kerosene only, with kerosene presumably used for lighting. In households using energy sources in addition to electricity and LPG, typically only one other fuel was used, that fuel being charcoal or kerosene. In Angola, where LPG has been heavily subsidized for decades and spending on LPG is only barely more than 1 percent of total household expenditures, the continuing use of charcoal by households using LPG may signal a cultural preference. In Nigeria, where neither kerosene nor LPG has been subsidized for many years, continuing use of kerosene might possibly suggest unreliable LPG supply.

_Source_ : World Bank staff calculations using household survey data. _Note_ : Ranking is in order of decreasing number of households falling under any given combination. Only the top choices covering about two-thirds of all households, subject to inclusion of at least two combination choices containing LPG, are shown. The households in Nigeria add up to 73 percent to show two categories of LPG users. HHs = households.

A more comprehensive list of combinations of energy sources used by households, taking Ghana for illustration, can be found in Table A2.1 in annex 2. There were 35 distinct combinations of household energy sources in urban areas, 43 in rural areas, and 48 nationally. Not all combinations are shown because, although the questionnaire included sawdust, animal waste, and other fuels as possibilities, fewer than 1 percent of all households in urban areas, rural areas, and nationally reported non-zero expenditures on these fuels or cited them as their primary fuels for cooking. There were so few such households that they are omitted from the table.
