Key takeaways On average, electric stoves use 1,000 to 3,000 watts of electricity. Ovens use 2,000 to 5,000 watts of electricity on average. Using a stove and oven for a combined 7 hours per week will use about 1,022 kilowatt-hours (kWh) of electricity per year.
Let's say you use a standard oven or range with a maximum power consumption of 4000 watts and an average wattage of 3000. If you run your oven for one hour at the average electricity rate of 15 cents per kilowatt-hour, the cost would be $0.45 (3 kW × $0.15).
While they may not be the most commonly used appliance in your home, ovens are among the most energy-demanding. In fact, aside from your fridge (which runs 24/7), your oven is likely responsible for the highest energy consumption out of all your kitchen appliances.
Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.
The most common reasons for a big jump in your electric bill include changes in your lifestyle, increased usage of energy-hungry appliances, and sudden weather changes.
If you want to test how much power your appliances and devices are using in standby mode, you can buy an electricity usage monitor device. These devices allow you to plug in various tech or appliances and check how much power they're actually using, even in standby mode.
Air Conditioning & Heating
Your HVAC system uses the most energy of any single appliance or system at 46 percent of the average U.S. home's energy consumption.
The most electricity is consumed by a fridge/freezer, electric range and dishwasher. This is mainly because they are used so much. The espresso maker uses 450 kWh annually, at one cup a day. For cooking purposes, an electric slow cooker, Instant Pot or microwave will use less energy than will an electric range.
Electric Bill For Leaving Oven On Overnight
For example, let's say your oven uses 2000 watts and it was on for 12 hours. That's about 24 kilowatt-hours (kWh) of electricity. If electricity costs about 12 cents per kWh where you live, that would add about $3 to your bill.
As technology advances, appliances become more energy-efficient. If your current microwave is consuming more energy than newer models, it could be contributing to higher utility bills. Upgrading to an energy-efficient microwave reduces your environmental footprint and saves you money in the long run.
The higher an appliance's wattage, the faster it consumes electricity. Typically, home electric ovens range between 2,000 and 5,000 watts, depending on their size, design, and features. A larger oven or one with more cooking functions might need more power.
Air fryers offer advantages, particularly regarding energy efficiency and cost savings. For instance, a typical 4-quart air fryer uses 1,500 watts, almost half the power consumption of a regular full-size oven. An air fryer requires half the electricity, making it 50% more efficient than a full-size electric oven.

When your devices are plugged in but not in use, they consume electricity, known as the phantom effect. As a result, unplugging those devices can save electricity. Do not worry about unplugging every gadget; simply plug what you can into a power strip so you can unplug less.
The Givoni or Woods diagrams show a direct relationship between air speed and the drop in temperature felt by users of the room. In this case, a ceiling fan will consume between 20 and 50 watts (still a long way from the consumption of an air-conditioning system (800 to 1500 watts, i.e. 30 to 40 times more).
Electricity Usage Monitors
Before using a monitor, read the user manual. To find out how many watts of electricity a device is using, just plug the monitor into the electrical outlet the device uses, and then plug the device into the monitor. It will display how many watts the device uses.
Check your meter.
A final check you can safely perform yourself is to go to your meter and turn off all the circuit breakers. Then watch the meter—if it continues to go up, something is still pulling power from your connection.
Faulty electrical wiring could cause a sudden increase in electricity consumption, or your electrical meter may be broken. If you continue to see a higher than expected electricity bill, even after taking all of the necessary steps to troubleshoot the exact cause, it may be time to call a certified electrician.
