If you've purchased your appliances in the past 40 years, chances are, they were built with energy efficiency in mind. Energy efficiency typically translates into lower energy bills, which makes these appliances less expensive for you to run and helps you to keep more cash in your wallet each month.

But there are also appliances that could secretly run up your electric bill and drain your bank account. Want to lower your energy costs and your financial stress? Here are 10 common household appliances that could be sucking energy and driving up your costs, even when you're not actively using them.

Now Available: The Definitive Guide to Retirement Income

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.

That is exactly what The Definitive Guide to Retirement Income helps answer.1 It covers what your retirement could actually cost, which income sources are worth using, and the withdrawal math that decides whether the money lasts. It is free today from Fisher Investments. Read More Here ›

Gaming console

Do you need another reason to tell the kids to stop playing video games? Their Xbox isn't free to run — it costs approximately $37 annually, according to Payless Power. That might not seem like much, but when you consider that you could be using $37 to help pay down your grocery bill, you may feel a lot better about nagging the kids to turn off the console.

Computer

Your computer may be essential for work, but those working remotely may actually be spending money as part of their nine to five. A desktop computer costs up to $233.60 to use annually, depending on energy usage, according to Nexamp. Meanwhile, your laptop is slightly behind it, costing about $32.70 to run each year.

Television

A television isn't necessarily expensive to turn on, but it's also not free. If you watch TV — or just leave it on in the background — for 21 hours a week, Energy Sages says you could be spending $15.54 a year for your TV habit.

Released: The Definitive Guide to Retirement Income (Sponsor)

Most people spend their entire working lives focusing on one thing: growing a pile of money. Then they retire and discover the skill they actually need is close to the opposite. Turning that pile into steady income, year after year, through good markets and bad, without ever running out. It may be the least discussed and most consequential transition in personal finance, and plenty of otherwise careful investors walk into it with no real plan.

That is exactly what The Definitive Guide to Retirement Income helps answer.1 It is a free guide from Fisher Investments covering what your retirement will really cost, where the cash flow should come from, and how much you can safely withdraw each year. Learn More Here ›

Washer and dryer

Your clothes have to get clean, but did you know that using an at-home washer and dryer isn't necessarily more affordable than paying per load at a laundromat — though it's certainly more convenient! The average household will spend up to $240 a year in electricity costs to run a washer and dryer, according to Home Guide, and that doesn't even take into account the amount of money you'll spend on water or laundry detergent.

Space heater

A space heater is actually shockingly expensive to run, so don't get any big ideas about saving money by turning down the heat and running space heaters in every room. A space heater will cost you an average of $50 a month in energy costs, according to CNET, and that's per heater. So, if you're running more than one, you'll need to tack an extra $50 on to your monthly bill for each additional heater.

Water heater

How much do you enjoy those warm showers? Hopefully quite a bit, because your electric water heater isn't cheap. On average, you'll pay $426 a year to run your electric water heater each day. Of course, that number can increase dramatically depending on how many people are in your home, and how long of a shower each one of them takes.

EV home charger

The electric vehicle may be saving you money in gas dollars, but the charger is running up your electric bill. Kelly Blue Book says that you could see an extra $769.44 added onto your electric bill each year that you use a home charger for your electric vehicle.

Hair dryer

This might come as a surprise, but a hair dryer uses significantly more energy than you might expect, especially when you consider that you're only using it for a few minutes a day at the most. The Energy Sages say a hair dryer can use $15.54 in energy costs.

Ceiling fan

A ceiling fan could help regulate the temperature within your home and aid in saving on cooling costs, but, if you're just using it out of habit, it might be time to turn it off. Home Guide says running your ceiling fan every single day could add an extra $65 a year in energy costs.
