If your electric bill feels too high, it helps to know where the money actually goes. In a Texas home, a handful of high-wattage devices run for hours at a time and quietly account for most of the bill — while the small electronics people worry about barely register. Here's the real breakdown, biggest first.
The short answer
Air conditioning is the biggest electricity user in a Texas home — often 40–60% of a summer bill. After cooling, the largest draws are the electric water heater, a pool pump (if you have one), the clothes dryer, and the refrigerator. Anything that makes or moves heat for hours at a time is what runs up the bill; chargers and gadgets are a rounding error by comparison.
The Texas Bill, Ranked
Every home is different, but the order rarely changes much in Texas. These are typical shares of a summer electricity bill and rough monthly energy use for a mid-size home. Dollar figures assume about 14¢ per kWh — use the comparison tool to see your own rate.
| What it is | Share of summer bill | Typical monthly use |
|---|---|---|
| Central air conditioning | 40–60% | 900–1,500 kWh |
| Electric water heater | 12–18% | 300–500 kWh |
| Pool pump (single-speed) | 10–20% | 300–600 kWh |
| Electric clothes dryer | 3–6% | 60–120 kWh |
| Refrigerator / freezer | 3–5% | 40–90 kWh |
| Oven, range, dishwasher | 2–5% | 50–100 kWh |
| TVs, computers, electronics | 2–4% | 40–80 kWh |
| Lighting (LED) | 1–3% | 15–40 kWh |
#1 — Air Conditioning (Nothing Else Is Close)
In a Texas summer, cooling is the whole ballgame. As outdoor temperatures push past 100°F, the AC runs longer and harder just to hold the thermostat, and a central system can pull 1,000–1,500 kWh in a single peak month. That is why bills nearly double between April and August even though nothing about your plan changed — your summer usage simply moved up. Raising the setpoint a few degrees, servicing the unit, and sealing the attic do more for your bill than any other single action.
The math
Cooling at 1,200 kWh in August × 14¢ = about $168 for AC alone — more than most households spend on everything else combined that month.
#2 — The Electric Water Heater
A storage water heater keeps a full tank hot 24 hours a day, reheating on a thermostat whether or not anyone turns on a tap. That standby reheating is why it ranks so high despite the short bursts of actual hot-water use. Setting the tank to 120°F instead of 140°F, fixing dripping hot taps, and adding an insulating blanket on an older tank all trim a draw that runs every hour of every day.
#3 — The Pool Pump (a Quiet Texas Budget-Killer)
A single-speed pool pump is one of the most underestimated energy drainers in Texas. Run 8–12 hours a day through the cooling season, it can rival the water heater for total monthly kWh. Cutting runtime to what the water genuinely needs, running it in shorter cycles, or upgrading to a variable-speed pump can shave a large slice off a summer bill — see how to lower your Texas electricity bill for the full playbook.
What Doesn't Run Up Your Bill
The things people fixate on are usually the smallest. Modern LED lighting, phone and laptop chargers, Wi-Fi routers, and most electronics on standby each cost a few dollars a year. They are worth tidying up — see does unplugging appliances actually save money? — but they will never move your bill the way the AC and water heater do. If you only have time to fix one thing, fix the cooling.
Cutting kWh is only half the bill
The other half is your rate. Because the cheapest plan changes with how much you use, compare every plan in your city at your real usage — a high-usage home often has a different cheapest plan than the advertised winner.
Find My Cheapest Plan →Why This Connects to Your Plan
Knowing your biggest users tells you your usage level — and usage decides which plan is actually cheapest. A small apartment that uses 600 kWh and a four-bedroom home with a pool that uses 2,500 kWh sit at completely different points on every plan's pricing curve. A plan engineered to look cheap at exactly 1,000 kWh can quietly become the wrong choice at either extreme. That's the 1,000 kWh illusion, and it's why we rank plans at your real usage rather than the marketing number.
Common Questions
What uses the most electricity in a Texas home?
Air conditioning, by a wide margin. In a Texas summer, central AC commonly accounts for 40–60% of a home's electricity use. After cooling, the biggest draws are electric water heating, a pool pump if you have one, the electric clothes dryer, and the refrigerator. Lighting, once a major cost, is now a small slice because LED bulbs use about a fifth of what old incandescent bulbs did.
What is the most expensive thing to run in a house?
Central air conditioning is the single most expensive thing to run in almost every Texas home. A central AC working through a 100°F afternoon can pull 1,000–1,500 kWh over a summer month — at about 14¢/kWh that is roughly $140–$210 for cooling alone. A single-speed pool pump running long hours is often the second most expensive item, followed by an electric water heater.
What runs up your electric bill the most?
Anything that makes or moves heat, run for long hours. That means air conditioning, electric water heating, electric resistance space heating in winter, and pool pumps. These are high-wattage devices that run for hours at a time, so they dominate the bill. Small electronics and chargers draw very little by comparison, even left on all day.
Which appliance is a real energy drainer?
After the AC, the electric water heater is the classic hidden drainer — it reheats a full tank around the clock whether or not anyone uses hot water. A single-speed pool pump is another, often running 8–12 hours a day all summer. The electric clothes dryer is a short-but-intense draw (about 2–4 kWh per load).
Does the cheapest plan depend on how much electricity I use?
Yes. Because your bill is usage times rate, and many Texas plans are priced to look cheapest at exactly 1,000 kWh, the genuinely cheapest plan changes with your usage. A high-usage all-electric home with a pool can be cheapest on a different plan than a small low-usage apartment. That is why you should compare plans at your real usage, not the advertised 1,000 kWh number.
