What Causes High Electric Bills?

High electric bills can be caused by a combination of factors, including increased energy usage, utility rate hikes, inefficient appliances and poor home insulation. Most homeowners encounter one or more of these issues at some point in time.

Inefficient appliances

Older home appliances aren’t as energy efficient as newer models, so they pull more energy that can drive up your bill. For instance, an older fridge uses about 35% more energy than an ENERGY STAR-certified unit.

Continuous use of smaller electronic devices, like laptops and TVs, can also contribute to higher bills.

To help control costs, look for the ENERGY STAR label when it’s time to upgrade appliances. For smaller electronics, plug them into a power strip and switch the strip off when you’re done. 

Poor insulation

If your home isn’t adequately insulated, your HVAC system could be working overtime to keep your place warm or cool — and you’ll be paying more for it. 

Check for drafts around windows and doors, and seal any leaks with caulk or weatherstripping. If you think your insulation is lacking, consider an energy audit to identify which areas of the home need addressing. You might find your bills become more manageable after insulating the attic, crawl spaces or the basement.

Excessive usage

Sometimes, the cause of a higher energy bill is your usage habits, like lights left on in empty rooms, longer showers or running the dishwasher or washing machine when half-full. Your thermostat settings can make a big difference, too.

To help you save, consider switching to LED bulbs, washing clothes in cold water and only running the dishwasher when it’s completely full. Try adjusting your thermostat by just a few degrees — a programmable thermostat can make this even easier to do.

Seasonal changes

Electricity bills often spike along with the seasons. Summer air conditioning can significantly increase your monthly bill in hotter cities like Dallas or Phoenix, while winter heating costs rise sharply in colder states like Minnesota or Michigan. Even shorter daylight hours means more reliance on artificial lighting, while around the holidays, festive lights and decorations can drive bills higher, too.

You can help lessen the impact of these seasonal swings. Schedule HVAC maintenance before the season begins to make sure it’s running at peak efficiency. A programmable or smart thermostat can help manage indoor temperatures while you’re at work or asleep. 

If you love holiday decor, consider switching to LED light strands and using smart plugs or timers to limit run times. This way, you can still enjoy the sparkle without as much sticker shock when the bill arrives.

Guests or roommates

More people in your home leads to more electricity use. If you have guests visiting or roommates, that means additional showers, more cooking and more charging of devices. Even one additional roommate can significantly increase water, heating and power usage. 

Longer billing cycles

Depending on the month or when you start service, your billing cycle might be longer than you think, so you could see a higher bill due to the extended time frame. If your statement seems unusually high, check the number of days in the cycle and compare it to your usual usage.

Rate increases and demand pricing

Utility rates don’t stay fixed — they can change year to year or even more often as providers increase rates, as well as during the day during peak times when demand is highest.

While you can’t do much to control overall rate increases, you can minimize the effects of demand pricing by shifting heavy-usage tasks like running the dishwasher or doing laundry to off-peak hours. Many utility providers share their peak pricing schedules so you can plan accordingly. 

What renters should know

For renters, electricity is often the largest share of utility expenses. Looking at average apartment utility costs in the U.S., renters pay anywhere from $70-$190 per month on electricity, depending on apartment size and location.

Some landlords include utilities in rent, but not always. Understanding what’s covered before signing a lease prevents surprises. When you’re touring a property, don’t hesitate to ask about utility costs upfront.

What homeowners should know

As a homeowner, you’ll likely spend more on utilities compared to a renter, even if you live in a similarly sized place. You’ll need to know how to set up utilities in your new house, as well as take care of maintenance responsibilities like HVAC servicing. Factoring these into your budget can not only help you avoid bill shock, but also make your home more energy-efficient in the long run.

Taking control of your energy costs

High electricity bills can feel discouraging, but the cause might be easy to address. From building better usage habits to sealing up drafts, small steps can lead to meaningful savings.
