How Much Electricity Does Your Computer Consume?

Remember the early 2000s, when you’d share a computer with the rest of your family, and everyone would take turns surfing the web in the living room?

Well, those days are over. Today, pretty much everyone has a personal laptop or desktop, and most of us keep our laptops constantly plugged in, and ready to fire up.

Now, have you ever thought about how much energy your computer consumes on a monthly basis, and how you can cut back on this energy usage? In this blog post, we walk you through how much electricity it takes to run different computers, and give you tips on how to save energy!

How Much Electricity Does It Take To Run Your Average Computer?

The amount of electricity it takes to power your company varies according to the type of computer you use, as well as what you use it for.

In this section, we’ll discuss the amount of energy consumed by desktops, laptops, and tablets, so you can get a better sense of how much energy you’re using each month.

Desktop

Generally speaking, desktop computers use 60 to 300 watts per hour. Yes, that’s a pretty big range, but that’s because the amount of energy that’s required to power a desktop fluctuate based on what the desktop is used for.

For instance, if you’re using your desktop to work on a school or work assignment, and you’re just using Microsoft Word and/or Google, this won’t consume much power. But if you’re a hardcore gamer and you play tons of computer games on your desktop, then your desktop’s energy consumption will scale up accordingly.

Laptop

As you may guess, laptops consume a lot less energy than desktops – they only use approximately 30 to 70 watts per hour. Again, the exact amount that your laptop uses will depend on what you’re using your laptop for.

Another factor that influences the amount of energy a laptop uses is the screen (and brightness of the screen). If you own a mini laptop with a small-sized screen, then this will definitely consume less energy. The same goes if you make it a point to keep your screen brightness on “low”, or turn off the backlight function on your keyboard.

Tablet

Out of the lot, tablets are the smallest devices, and it naturally follows that they consume the least amount of energy. On average, tablets use just 15 to 30 watts per hour, which means that four hours’ worth of tablet usage is roughly equivalent to one hour’s worth of desktop usage.

Again, whether you keep your tablet screen turned to maximum brightness or you choose to use a lower brightness setting plays a big role in impacting the amount of energy your tablet consumes.

2 Tips To Save Electricity On Your Computer Usage

Want to go green, and cut back on your energy bill at the same time? Here are two tips that will help you save electricity from your computer usage.

1. Enable Sleep Mode

Ever gotten to your computer in the morning, and realized it’s been running all night long?

To avoid wasting energy unnecessarily, make sure you enable sleep mode. Once you’ve activated this setting, your computer will automatically power down after an extended period of inactivity.

2. Use A Single Power Strip

To make it easier for you to shut down your computer and related accessories, consolidate all your devices and plug them into a single power strip.

This way, when you want to stop using your computer, you can flick a single switch and have everything shut down at once.

Want To Save The Environment (and reduce your electricity bill)?

To go green and reduce your electricity bill at the same time, consider purchasing your electricity from a retailer that offers green electricity plans.
