Hot states have the biggest bills: partly true
Partly The claim: “Hot states have the biggest bills” Only 4 of the 10 hottest states are among the 10 highest bills. Hot states use somewhat more power, and their prices run lower than in the coolest states (14.5 against 19.4 cents, medians).
Heat and bills: r = +0.34
Cooling degree-days are NOAA's 1991 to 2020 normals for each state. The typical bill is average kWh per account times the average price (EIA monthly, 2025). Across 48 states the link between cooling degree-days and the bill is +0.34, with monthly use +0.67 and price -0.36.
The 10 hottest states, from Florida to Arkansas, have a median bill of $159 and a median use of 1,087 kWh; the 10 coolest, $135 and 658 kWh.
Each dot is a state
48 states; r = +0.34 for the bill, +0.67 for use in kWh, -0.36 for price. Hawaii, DC and Alaska have no usable degree-day figure in our file.
Summer peaks inside a yearly average
Heat does raise bills in the hot months: the table below shows January and July for the five hottest states. A yearly average blends all twelve months, and hot states pay lower prices (14.5 cents against 19.4 in the coolest ten, medians), which takes back part of the extra use. Among the 10 highest bills the median cooling degree-days figure is 991, against 778 for all 48 states.

Limits
A degree-day normal averages over the whole state, while a bill belongs to one home. We do not have air-conditioning ownership by state, so we cannot say how much of the use is cooling. Alaska, District of Columbia and Hawaii have no usable degree-day record in our file; Alaska's normal in the NOAA file is a negative number.

Questions
Do hot states have the biggest electric bills?
Not on average: r = +0.34 between cooling degree-days and the typical monthly bill across 48 states.
Which hot state has the highest bill?
Alabama among the 10 hottest, at $185.43 a month (2nd of 51).
Which state has the highest bill overall?
Connecticut at $207.35, with 460 cooling degree-days (rank 34 of 48).
Do hot states use more electricity?
A little: r = +0.67 with monthly kWh. The 10 hottest use a median 1,087 kWh a month against 658 in the 10 coolest.
Are hot-state prices higher or lower?
r = -0.36 between cooling degree-days and price; medians are 14.50 cents (hot) and 19.39 (cool).
What are cooling degree-days?
A measure of how far daily temperatures sit above a base temperature, summed over the year. NOAA's 1991 to 2020 state normals are used here.
Why do some states have no figure?
Alaska, District of Columbia and Hawaii have no usable figure in the NOAA statewide degree-day file we use.
How is the typical bill defined?
Average kWh per account times the average price, EIA monthly data for 2025, averaged over the months. It is a statewide average, not any one utility's bill.
