how many watts does a monitor use

If you are looking for the led monitor wattage, then you are on the right page. It contains dell monitor power consumption watts guide. So How Many Watts Does A Monitor Use?

A typical desktop computer uses about 65 to 250 watts. To find the figure for your particular computer you can contact the manufacturer (not me), or see my section on measuring electrical use. Add another 20-40 watts for an LCD monitor, or about 80 watts if you have an old-school 17″ CRT.  And don’t forget related devices.  My cable modem uses 7 watts, my D-Link DI-604 router uses 4.5 watts, and my Motorola phone box for use with Vonage uses 2 watts while idle (3 when I’m on the phone).

Most laptop computers use about 15-60 watts, far less than desktops.

How Many Watts Does A Monitor Use

With most devices you can look at the label to see how much energy they use, but that doesn’t work so well with computers because the label gives the theoretical maximum, not the typical amount used. A computer whose label or power supply says 300 watts might only use about 70 watts when it’s actually running, and only 100 even in peak times with serious number-crunching and all the drives spinning.

As long as your computer goes into sleep/standby when you’re not using it, your computer doesn’t use squat for electricity, compared to the rest of your household.  You’ll save a lot more energy by addressing your heatingcooling, and lighting use rather than obsessing over your computer.  For most people, their computers’ energy use is not a significant portion of their total use, even if they use their computers a lot.  Of course, you should absolutely make sure your computer is set to sleep automatically when you’re not using it, because it’s silly to waste energy, but your computer likely isn’t even close to being the biggest energy-waster in your home.  (See more about sleep/standby.)  If you take one thing from this page, it’s that you should set your computer to auto-sleep after 15 minutes or so of inactivity.!1&btvi=1&fsb=1&xpc=y1jKhWdfaP&p=https%3A//

How much it costs to run your computer

To calculate your costs use this formula:

Watts  x  Hours Used   x  Cost per kilowatt-hour = Total Cost

For example, let’s say you have a big high-end computer with a gaming-level graphics card and an old CRT monitor, and you leave them on 24/7.  That’s about 200 watts x 24 hours x 365 days/yr = 1,752,000 watt-hours, or 1752 kilowatt-hours. If you’re paying $0.36 per kWh, you’re paying $631 a year to run your computer.  (In California, PG&E’s highest tier is $0.33/kWh, and the average in Hawaii is $0.36/kWh. source)

Let’s try a different example:  You have a computer that’s less of an energy hog, like in iMac G5 20″, which uses about 105 watts, and you’re smart enough to turn it off or sleep it when you’re not using it.  You use it for two hours a day, five days a week.  That’s 105 watts x 10 hours/week x 52 weeks/year = 54,600 watt-hours, or 54.6 kWh.  If you’re paying 10� per kilowatt-hour, then you’re paying about $5.50 a year to run your computer.

That’s quite a range, $5.50 to $631 a year.  It really depends on what kind of computer it is, how much you use it, and your local rate for electricity — and especially whether you turn off the computer when you’re not using it (or at least sleep it).  Both the examples above are extremes. I used to have only one example somewhere in the middle but then I’d see people on blogs and forums misquoting it by writing, “Mr. Electricity says a computer costs about about $150/yr. to run.”  No, that is not what I said. I said that was just an example.  Your situation is almost certainly different, and you need to consider all the variables listed in the first sentence of this paragraph.

Sleep & Screensavers

Modern computers automatically go to “sleep” when you haven’t used them for a while, drawing only 0-6 watts.  (Putting the computer to sleep also sleeps the monitor, on most models.)  In the past, turning on the sleep setting was the most important way to save on computer energy use, but now that the sleep option is turned on by default out of the box, that’s pretty much done for you.  Just make sure you don’t override it by turning it off.  Of course, you can go the other direction, tweaking your sleep and power usage settings, especially by having your computer sleep sooner after a period of non-use.  Here’s where to set your options:

There are various flavors of sleep, including Sleep, Standby, and Hibernate.  It’s not terribly important to understand the difference between them. In a nutshell, hibernate saves your workspace (all the open windows) and then turns your computer off, so it saves more energy than standby, but a hibernating computer takes longer to wake up.  For the curious I have a separate article about the differences between Sleep, Standby, and Hibernate.

A screensaver that shows any image on the screen doesn’t save any energy at all, on either the monitor or the computer.  You save energy only if the monitor goes dark by going to sleep.

Granola power saver

A Windows/Linux app called Granola constantly optimizes your computer’s processor speed to save electricity.  They claim savings of 10-35% without sacrificing performance, and laptop users will get more battery life off a single charge.  Granola is free for individual users, and $8 per machine for business users.  It’s not available for Macs.  Note that Granola isn’t a substitute for sleeping your computer, it’s a complement to sleep.  If you had to choose one or the other, you’d definitely save more by having your computer auto-sleep rather than using Granola.  But you don’t have to choose one or the other, you can do both.

My recommendations

  • Set the Power settings on your computer to automatically go into Sleep/Standby mode after 15 minutes or so of inactivity.
  • Use a laptop computer. They use lots less energy than desktops.
  • If you use a desktop, use an LCD monitor. They use lots less energy than CRT’s.
  • Turn your computer off when you’re done for the day.
  • Use a Mac, or use the Granola power saver for Windows/Linux. Macs have generally used less electricity than most PC’s.  (I haven’t had a chance to test current models, but I don’t expect that a lot has changed.)
  • Use a power strip so you can easily turn off all your computer accessories at once. BITS makes a special power strip that goes one step further, automatically cutting power to peripherals when you turn your computer off.

Specific Models

Here are some figures for some specific models.  Don’t write to me to ask me how much your particular computer uses, because I didn’t make your computer and unlike you, I don’t have access to it. Contact the manufacturer or buy a watt-hour meter.

Yes, it doesn’t make sense that the Dell GX620 is listed as using more power when it’s off than when it’s sleeping, but I’m just reprinting the numbers from Dell’s specs.

Dell Pentium 4’s from Dell’s website.  iMac G5 from my own measurements (except the max, which is Apple’s spec).

The University of Pennsylvania has a somewhat more recent list of Mac / PC wattage.

You won’t wear your computer out any faster by cycling it once a day, or even a few times a day. Modern computers just aren’t that fragile. I did hardware troubleshooting at Apple, by the way. If you don’t believe me, maybe you’ll believe Jonathan Koomey, a project scientist at the Lawrence Berkeley National Laboratory, who says, “PCs are not hurt by turning them on and off a few times a day.” (Wall St. Journal) The useful life of a computer these days is only a few years anyway. The computer will become obsolete long before you wear it out, no matter how often you cycle it. Bottom line: Turn your computer off when you’re done with it (or simply Sleep it), and don’t worry about it. (more on this topic…)

It also doesn’t take more energy to start a computer than to keep it running. The only extra energy it takes to start a computer is the two minutes or so it takes to start up, which is barely different than any other two minutes’ of use. You’ll always save energy by turning your computer off when you’re not using it. Of course you don’t have to turn it off since you can easily use the sleep or standby mode instead.

The myth of “turning it off uses more energy than keeping it on all the time” exists for just about every device that exists, and it’s wrong in every single case, in practical terms. (Meaning, you will never, ever, ever see any savings on your electrical bill by keeping something on all the time vs. turning it off. Period.) You will always save electricity by turning your device off when you’re not using it (or sleeping it, if it’s a computer).

Whether to use a laptop to save energy

Some people think it’s a bad idea to replace desktops with laptops even though they use less energy, because they’re more likely to require repair, those repairs are more expensive than desktop repairs, many users thus choose to replace their broken laptop rather than getting it fixed, and laptops require disposal of chemically-laden batteries when they wear out.  While these things are true, I think the average person (and the environment) will still come out ahead over all by using a laptop over a desktop, because only a fraction of laptops will actually break and get replaced.  If every laptop failed like this during its life (or even if most of them did), we could easily say that it would be better to stick with desktops.  But since only a fraction of laptops fail, I still think there’s a net savings by using laptops.

Energy-Efficient PC’s

In June 2007 the EPA started giving an “Energy Star” rating to energy-efficient computers.  While this is important, sleeping your computer when you’re not using it is more important.  An inefficient computer that sleeps when you’re not using it uses far less energy than an Energy Star computer you keep running 24/7.  This is so important I’m going to repeat it: Making sure you sleep your computer when you’re not using it is way more important than what kind of computer you use.

Computer power supplies are only 55-80% efficient.  That means with a cheap power supply, nearly half the energy consumed is wasted.  At least 80% efficient power supplies are required to get the EPA Energy Star label, but even then up to 20% of the energy consumed is wasted. (Tom’s Hardware)

There are a handful of ultra-low-energy PC’s available.  They all come with some flavor of Linux instead of Windows, and typically come with Firefox for web browsing and Open Office for productivity.  The low-power processors they use also mean that they’re a bit slow. (e.g., The Linutop 2’s AMD LX processor runs at 500 Mhz.)

  • Zonbu. Their $300 Mini desktop uses only 15 watts.
  • Linutop. Makes tiny PC’s that use only 5 to 8 watts, for around $400.
  • Everex gPC. Claims to use only 2 watts on average but I’m skeptical because their website is short on details.

Energy required to make a computer

This paper said it took about 6400 megajoules of electricity to make a desktop computer and a 17″ CRT monitor in 2000, which would be about 1778 kwh — or as much electricity as the typical household uses in two months.  Yet another reason to buy used.  I’ve purchased my computers on eBay since 1998.

The Internet doesn’t use as much electricity as you might think.

Computers account for only a fraction of worldwide electrical use, even with the burgeoning Internet. Air conditioning, lighting, and refrigeration account for a lot more. In fact, as inefficient CRT monitors are being phased out in favor of newer LCD screens, and as more people replace their desktop with laptops, computer energy use isn’t likely to rise very much in the coming years.

The site UClue gives an outrageous estimate for the Internet’s use of electricity, clocking it at 9.4% of all electricity used in the U.S. The first problem is that they count individual users’ computers, even though those computers don’t power the net. And even though those computers do use the net, their owners aren’t surfing for 100% of the time  the computer is on. Further, even if there were no Internet, office employees would still use computers all day (like they did before the Internet). And for home users, if someone’s not on the Internet, they’re probably watching TV, which uses even more energy. So personal Internet use isn’t “new” energy being used. Finally, I think UClue is overestimating the amount of energy used by end users’ computers in the first place. (And their link to their source for that figure is dead.) So taking personal PC’s out of the picture and looking only at the energy to run the datacenters (including the costs to cool them), UClue’s figure drops to only 1.2%.

We should also consider how much energy the Internet saves us. For starters, take a look at this website; thousands of people have used it to learn how to reduce their consumption. That’s nothing to sneeze at.  And online shopping means you can buy stuff from your home without driving somewhere, meaning more energy savings. Online maps let us find our destinations easier with less driving, too. Then there’s the fact that email lets us send messages and documents without requiring a fossil-fuel vehicle to physically deliver the hardcopy. So the Internet’s share of energy use should be certainly be contrasted with the amount of energy it saves.

Now let’s talk about the electricity to power websites. If you had to have a separate computer to host each website, then we’d have a big energy problem, but fortunately that’s not how it works. A single computer (server) can host hundreds or even thousands of websites. In fact, that’s what made websites affordable to the masses in the late 90’s. If you had to rent the whole computer from your host then the cost would be astronomical. But your site is on the same server with lots of other folks’ sites, which is why they call it shared hosting. By contrast, dedicated hosting is when you rent an entire server for yourself. But even then, you can put dozens or hundreds of sites on your server, as I’ve done with mine. And for my server, I chose a host that purchases carbon offsets to offset the pollution caused by generating the electric to run the server, which is why you see the “This site is green” logo on the bottom of the page. Also, in October 2008, they announced they were spending $1 million to upgrade their old servers and cut their energy costs in half.

The very largest sites (Google, Yahoo, eBay) require multiple servers just to run their one site. But those sites are used by millions of people every day. The energy use on a per-person basis isn’t that great. Also, the largest companies have been taking bold steps to reduce their energy footprint. For example, in 2007 Google built a massive 1.6-megawatt solar system at its headquarters in California. It generates 30% of Google’s peak demand, and around two million kWH a year. It’s the largest corporate solar install in the U.S. (There are larger installations at utility companies, but this is the biggest for a company generating its own electric.) Google has a page where you can see how much electricity they generated in the last 24 hours and the last 7 days. You can also see a flyover video of their installation. The system will take 7 years to pay for itself, and then will generate free electricity for another 18. (The lifespan of the panels is about 25 years.) It doesn’t end with this huge installation. In late 2007 Google announced its plans to develop a whopping one gigawatt of energy from renewable sources at a cost cheaper than coal, and to do it “within years, not decades”. Wow!

Yahoo is also addressing its energy footprint. Besides Yahoo cutting the carbon footprint of its data centers by 40%, they have a very progressive Commute Alternatives Program to encourage employees to not drive to work alone. It includes things like shuttles to transit stations, transit discounts, a carpool matching service, preferred parking for carpoolers, bike racks/lockers/showers, and free lunches, massages, and movie tickets to employees who participate in the program.

In short, there’s no need to scapegoat the Internet for electrical use — especially when things like cooling, heating, lighting, and refrigeration use so much more. And this site will give you lots of ammunition for how to use less.


AliExpress is a massively popular Chinese online retail service owned by Alibaba Group. It was launched in 2010 and hasn’t stopped its journey to becoming the ‘biggest online marketplace of the world‘ ever-since. AliExpress stands toe-to-toe even with Amazon in terms of buyers worldwide. It offers wholesale goods at direct-to-consumer prices from Chinese sellers.×280&!4&btvi=2&fsb=1&xpc=XrkRroOgKR&p=https%3A//

It also works as a great dropshipping model for a lot of e-commerce entrepreneurs. Along with a lot of good sides, AliExpress has some cons as well. The biggest problem is the shipping time of AliExpress orders, which is pretty long considering the goods come from China. Also, some orders can be very expensive after shipping charges and taxes.

So, it is a good thing to have some AliExpress alternatives whenever you don’t like its services. That’s why we are telling you about 21 best sites like AliExpress. Some of these websites offer cheaper prices and faster shipping on certain products. And, you can also use them to maintain a nice profit margin for your dropshipping business.


LightInTheBox is the perfect AliExpress alternative as it is also a Chinese e-Store. It sells hot and trending products across the globe. Their products range from phone and electronics to fashion, jewelry, shoes, bags, and many other items. You can find almost anything here at a very cheap price.

The delivery time of LightInTheBox is also similar to AliExpress as their warehouses are located only in China. But, you may get a faster shipping time due to having fewer orders to ship. You can pay for your orders with PayPal, Western Union, or your credit card.


Wish is a widely popular online marketplace where you can buy almost anything. From clothing to footwear, electronics, healthcare items, and many more things, you can get them all for an incredibly cheap price. They are also known to offer great deals and coupons to their new customers.

Their shipping time is also faster than AliExpress as their products come from sellers located in small countries. Wish also provides an advanced rating system that is very helpful for both the consumers as well as sellers. It helps promote good ones.


Overstock is a US-based online marketplace. It makes profit by selling wholesale products at a highly cheap price tag. A major portion of their stock is comprised of overstock from the major retailers or their seconds. You can find some really amusing deals here. The shipping time will also be lower as compared to the Chinese marketplaces. You can get your items within a week.

The product range of Overstock is incredible. You can find everything such as clothing, decor, kitchen appliances, and many more items. You can even find furniture and other big home items. So, you can use to fill your house with great stuff at a reduced price.


DealeXtreme, more popularly known as DX, is an amazing online marketplace. The website works in a very similar manner as ‘Wish’ and sells cheap products coming directly from sellers. It has partnered with many small businesses and sells its products to a wide base of audience.!5&btvi=3&fsb=1&xpc=XV2qLkqJQj&p=https%3A//

The shipping time is a problem with DX also because their warehouses are located in China. Apart from this, you can get some really worthy deals on DX. You should always keep an eye on their clearance sales for the best prices.


Gearbest is the perfect AliExpress alternative if you are looking to shop for the latest gadgets or electronic devices. It works with over 5000 Chinese brands and top suppliers to deliver the best products. It has products from top Chinese companies such as Xiaomi, Huawei, Lenovo, and many others. But, it isn’t just an electronic store.

You can also find a massive range of other products as well. The prices available on GearBest are reduced, and you can even reduce them with the available coupons. They also have warehouses in multiple countries. So, you can get faster shipping from the local warehouse.


BangGood is another Chinese e-commerce platform that provides worldwide shipping of cheap goods. You can find almost anything on this website, from clothing to electronics, and even home items. The prices available are marked down from their original prices. You can also get amazing deals during special clearance sales.

BangGood provides a free $20 coupon to every new user. The shipping time for BangGood orders is faster than AliExpress for certain products. However, the regular shipping time is similar.


ChinaBrands is a widely popular Chinese e-Store where you can buy products at wholesale prices. You can find almost anything on this website at a highly affordable price. Their shipping prices are also low but you will get a long shipping time. It is the perfect website for buyers who want the lowest prices but can wait for their orders for at least a month.

Most of the ChinaBrands sellers run their factories from China, and their warehouses are located there only. This is the reason for the considerably long shipping time.


Bonanza is a unique American online marketplace where you can find a great range of products. They have over 20 million items from more than 50,000 sellers. It is a growing e-commerce store where even you can sell your items. It is a preferred platform by more than 20,000 entrepreneurial sellers. You can find some really amazing handcrafted items and collectibles here.

For people looking to shop regular items, this store may disappoint you a little. The prices of some items may be a little higher than some Chinese stores. But, the quality provided will be worth it.
