What this climate costs you

Degree days measure how hard a building has to work to stay comfortable. They are the reason two identical houses have very different power bills, and they are the link between the weather here and what you pay every month.

Cooling degree days How much air conditioning the climate demands 2,517

Heating degree days How much heating the climate demands 2,115

Approximate annual cooling cost At 15.91¢/kWh, Texas average $400

Approximate annual electric heating cost Lower where heating is gas rather than electric $118

These are rough planning figures from degree days and the state electricity price, not a bill estimate. House size, insulation and fuel type move them a lot. See the full cost of owning a home in Mason County, where electricity is one line of eight.
