How much is the electricity cost for running a desktop computer for a year non-stop?
The biggest difference comes from the power usage of your computer setup.The next biggest difference comes from the price of electricity. And a final difference comes from power save mode in which unused drives and displays are shut off but the computer continues to run. I did not consider hibernate in which the CPU is shut down and the operating state saved but no computations actually done.I will base this on actual figures from my operating computers and NOT on the nameplate ratings which are usually maximums and not reached in real use.My laptop, about 6 years old but pretty powerful at the time has a 90W power supply but sitting here right now I measured 37W with the battery fully charged and operating off the charger.My year old higher end I5 desktop w/ UPS and with two displays and SSD, several hard drives, two DVDRWs, a high end graphics car and powered speakers draws 220W when fully on but draws only about 100W when in the power save mode (wakes up instantly when I hit any key) And it has a 650W rated supply.Electricity ranges from about 10 cents per KWH to 20 cents in the US.A year is 8760 hours.So the laptop on 24/7 would cost $32.40 at 10 cents and $64.80 per year at 20 cents.The desktop on 100% full power 24/7 would cost about $193 to $386.The desktop on full 10% of the time and power save 90% (thus averaging about 120W) would cost $106 to $212 depending upon the cost of electricity.So the answer is as low as $32 and as high as $212.P.S. comparing my numbers to Phillip Remaker's answer, mine are lower, I used electrical costs from half to 100% of his but the real difference is that I used actual measured typical power rather than the maximum from the nameplate.
How much does it cost in electricity to leave your computer on all day?
Anywhere between $0.20 and $2.00 depending on where you live, the power of your computer, and the usage. If it is idle and running all day then it will be close to the former. If you browse the internet a little bit, former. If you stream video all day, in the middle. If you are using very complex tasks such as gaming, cad work, video editing, or crypto mining… it will be the latter.

How much does it cost to run an average computer nonstop for a month running at maximum everything and running all the software you can possibly want to run but you haven't overclocked the cpu or anything?
My home Intel I5-2500 with 8GB and several hard and SSD drives and a number of USB peripherals, powered speakers and two monitors and a single higher end video card and a UPS draws about 1.9 Amps when fully on.That pulls .228 KW so in a month fully running 24/7 that way is 164 KWH.Assuming 15 cents per KWH its $24.6 per month.But I have mine hibernate when unused for several minutes. When on hibernate the current draw drops to under .15 amps, less than 1/10th. It restores in about 2 seconds with all my programs and data still displayed when I want it. I use it a couple of hours a night and more on weekends so it probably costing me around 2 bucks a month (my real rate of electricity is only 12 cents) to keep ready like it is.
How much power does it take to leave my computer on all night on lock mode, with no open programs running, and powering off my monitors? Please compare it to normal items as I don't know much of watts and electricity bills. How much would it cost?
Most desktops take about 100 W to run.Sleep mode where the power remains on but minimal keeping RAM alive takes but about 5 W.Hibernate mode which is where the RAM is imaged to HDD and the computer off except for power switch monitoring takes much less than 1 W.I’ll assume your electricity cost is 15 cents per KWH. Usually runs 10–20 cents per KWHAn 8 hour day of normal operation is 800W or .8 KWH so it costs you 12 cents.A 16 hour period of sleep mode uses 80 WH or .08KWH so it costs you 1.2 cents.A 16 hour period of hibernate or power off but plugged in and ready to hit power button would cost about 24 WH for about .2 cents.Pull the plug on all the parts (or use a power strip with a real power button) will use zero watts and cost zero cents for 8, 16, or 24 hours.Personally I leave my computer on 24/7 with a power down mode where it goes to sleep after 15 minutes and powers down the HDD drives when not used for more than 5 minutes. When I hit the mouse or keyboard it takes about 3 seconds to be back at ready and takes about 5 seconds for first disk access. Essentially I’m retired so I don’t use it 100% of the time but I use it from morning till I go to bed on and off frequently and often stream videos. So much of the time it runs at the sleep mode rate of usage and wakes up when i need it for 5–15 minutes at a whack. And that’s with all my unfinished work and programs loaded and about 30 browser tabs already open so I don’t have to restore anything.
Can computer use increase electricity bill a lot?
It may depending on what hardware you operate. A simple computer uses very little power. Things such as hard drives, the power light and computer fans use very little power. If however you have high powered peripherals added then these can really chew the power. High powered graphics cards use a lot for cooling and other power guzzlers could be the monitor and speaker systems attached. If your speakers have a sub-woofer then chances are they use a lot of power. A good clue about your computer could be the size of the power supply. They can be as small as 250-300W to power all of the hardware inside your tower and go up to 1,200W or more for high powered machines with multiple graphics cards. If you want to reduce consumption, turn the computer off whenever not in use, turn on the energy saving and screen saving modes by right clicking and choosing properties anywhere on your desktop; and disconnect or switch off the speakers when you don't need to be using them. You can easily save 500W or more when you do this, which is like having over 8x 60W light bulbs turned on or around 50 equivalent compact fluorescent lights!
Why does bit coin mining use so much power? Isn’t it just a computer that’s crunching numbers? If I played video games 24/7 on my computer I wouldn’t get a huge bill at the end of the month.?
When playing games, your GPU (Graphics Processing Unit, aka graphics card) will usually be at 95% capacity at max, give or take. Could be higher, could be lower. It depends on the CPU of your computer and the game itself.(I won’t talk about that here, a google search “bottleneck” will probably help you with that subject)When cryptocurrency-mining (such as bitcoin), you force your pc to be running at 100% capacity. This will consume the maximum amout of power it can take. This varies from GPU to GPU. Your pc will probably be turned on for longer while mining, as you won’t be gaming for a month straight, but many pcs that are mining will.TL:DR Consuming more power while on, and being on for longer, increase the electricity it uses, and as a result, your bill will be higher.
How much does one light bulb cost per hour?
An incandescent light bulb costs about 50 cents and lasts about 750 hours. If you were to leave a 100-watt bulb burning for 24 hours each day, 365 days per year, it would use 876 kilowatt hours per year. (1000 watts equals one kilowatt – “kilo” means a thousand.) A kilowatt-hour of electricity costs about 15 centsBut if you use Led light bulbs, it will cost very low. Let me explainIf you run a single incandescent bulb 5 hours a day for two years, it will cost you around $32 (depending on your energy rates). Most of that money is spent on electricity. If you run a single LED bulb 5 hours a day for two years, it will cost you $12. But – $9 of that is just for the bulb!Find out best Led light bulb for you, EnVision LED light bulbsEnVision LED light bulbs provide the market with a clean and bright light that turns on to full brightness immediately.

How many kilowatts does a 500 watt light bulb have per hour?
The answer is 0.5 kWs. Watts is not a time issue. One can draw and consume 500Ws in one sec or one hour or 1 day, it is a rate of power.Now if want to know how many kilowatt hours a 500 watt bulb draws in one hour it is 500W x 1 hr or 0.5kWHrs. In 2 hours it is 500W x 2 hrs = 1kWHrs.Kilowatt Hour is a measure of power consumed by time and the unit for what the power company charges.My home computer draws about 85Ws. In one hour that is 0.085kWHrs of power consumption and at my $0.12/kWHr cost 0.85 x 0.12 = $0.10/hr and for 30 days or 720 hrs my bill to run my computer for this time is 0.085 kW x $0.12/kWHr x 720 Hrs = $7.34 to run my computer for 30 days. Of course I dont keep my computer on 24/7.
Is it bad to have the PC running 24/7?
yeah its bad,despite of being a digital system it has mechanical parts which move like hard drive platter,cpu fan,graphic card fan,smps fan,dvd writes which tend to wear out if are on run continuously. also continuous heat deteriorates semiconductor components.hence leaving the system on 24/7 is an bad idea.
