Q: What is the principal energy source used by this household for lighting?

Ask for the principal source of fuel used by the household for lighting and circle the appropriate code. It is possible that a household may use more than one fuel at any one time but it is the one that is used most often that should be recorded. Only one code should be circled.

If the particular fuel used is not listed, write down the name of the fuel used in the space below the codes.
