My state,
jasonc, has a program called LIHEAP (low income heating electric assistance program), but if one's total income is too high, the program can't help. It used to be some of the churches would help members of their congregations who needed the extra assistance, but more and more, the churches cannot afford to do that. Many have become involved with food assistance programs.
The various electric/gas companies used to encourage bill payers to add a bit extra for a version of a 'Good Neighbor' program. But most don't do that any longer.
