As Connecticut braces for arctic-like weather in the coming days, various energy sources will be used to heat our homes. The American Community Survey data collects on what home heating fuel sources are used in the state – fuel oil, grid-connected natural gas, electricity, wood, etc. Among Connecticut households, the majority (about 644,000) use fuel oil of some type, followed by households using utility gas (i.e. connected to street lines) – about 432,000 households – and electricity in 206,000 households. Wood is used by about 26,000 households in Connecticut, and its use is especially prevalent in the northeast corner of the state.
