Know what energy really costs — then cut your bill

The average U.S. household pays somewhere between $100 and $180 a month for electricity, but that range hides an enormous amount of variation. A family in Hartford, Connecticut can pay three times what a similar household pays in Seattle for the same number of kilowatt-hours. The gap isn't random — it comes down to a handful of structural factors: how the local grid generates power, how tightly it's regulated, what fuel it burns, and how much electricity your climate forces you to use in the first place. This site exists to make those numbers legible: what a kilowatt-hour costs where you live, what a typical bill looks like, and what — if anything — is worth doing about it.

Why the price per kWh swings so much by state

Retail electricity rates in the U.S. span roughly 3x from the cheapest states to the most expensive. Four forces explain most of that spread:

• Generation mix. States sitting on cheap natural gas, hydro, or a paid-off nuclear fleet generate power for less than states that import fuel or lean on older, less efficient plants. Washington and Idaho, heavy on hydro, post some of the lowest rates in the country. Hawaii, which still burns imported oil for a meaningful share of its generation, has the highest.
• Regulatory structure. Some states run vertically integrated utility monopolies with regulated rates set by a public utilities commission. Others deregulated generation decades ago, letting competitive suppliers sell power over the incumbent's wires. Neither model is inherently cheaper — but deregulated states show far more variation between the best and worst deals available to a given household, because the price depends on which supplier and plan you pick.
• Transmission and grid geography. States with sprawling rural service territories spread fixed grid costs — poles, wires, substations — across fewer customers per mile. Dense Northeastern grids sit on expensive, congested real estate. Both push rates up for reasons that have nothing to do with the electricity itself.
• Climate and building stock. Rate per kWh is only half the story. A hot, humid state with air conditioning running six months a year produces a bigger bill than a mild state with the same rate, purely on usage. Older, poorly insulated housing stock compounds this in either direction.

Put together, generation mix and regulation mostly set the price; climate and home efficiency mostly set the usage. Your bill is the product of both, which is why two states with similar rates can have very different average bills, and two states with similar bills can have very different rates.

How to read the estimates on this site

Every number here is built from public, aggregate data — utility-filed rate schedules, EIA state-level generation and pricing series, and typical regional consumption figures — not a live quote from any specific utility. We show:

• A state average price per kWh, which is a blend across residential rate classes and, in deregulated states, across the range of offered plans.
• A typical monthly bill, built by applying that price to a regionally realistic usage figure (adjusted for heating/cooling degree days where we have the data).
• Ranges rather than single numbers where the underlying variation is wide, particularly in deregulated markets and for solar payback.

Treat these as a planning baseline, not a substitute for the number on your own bill. Your actual rate depends on your specific utility, rate plan, and, if you've shopped for a supplier, the contract you signed. See the full methodology for how each figure is sourced and updated.

A practical framework for lowering your bill

Most advice about cutting electricity costs jumps straight to gadgets. It's more useful to think in three layers, roughly in order of impact:

1. Fix the biggest load first. For most homes that's heating and cooling, followed by water heating. A thermostat setback schedule and basic weatherization typically beat any single appliance swap.
2. Shift what you can to cheaper hours. If your utility offers time-of-use pricing, moving laundry, dishwashing, and EV charging to off-peak windows can meaningfully cut the energy-cost line without changing how much you use.
3. Shop the supply side if your state allows it. In deregulated markets, the generation portion of your bill is a separate line you can shop independently of the wires. Switching suppliers is often the single fastest win available, with zero behavior change required.

We break each of these down in more depth on the electricity page, and collect specific, ranked tactics in our guides.

When solar actually pays off

Solar isn't universally a good deal — it's a good deal under specific conditions: electricity prices are high, sunlight is abundant, your roof faces the right way, and you plan to stay in the home long enough to recoup the upfront cost. A household in a high-rate state with strong net metering can see payback in six to eight years; the same system in a low-rate state with weak net metering policy might take fifteen or more — long enough that the math gets genuinely uncertain. The 30% federal tax credit narrows that gap everywhere, but it doesn't erase it. We walk through the full calculation, including the caveats salespeople tend to skip, on the solar page.

The bottom line

Electricity pricing isn't arbitrary, but it also isn't simple enough to summarize in a single national average. Where you live sets your starting price; your climate and home set your usage; and what you do about either — shifting hours, switching suppliers, tightening the building envelope, or generating your own — determines what happens from there. Start with your state's numbers, understand what's driving them, and use that to decide which of the levers above is actually worth pulling.
