Computer Energy Usage
Computer energy usage calculator
Energy usage based on the average Computer wattage of 68.
Computer Energy Usage Calculator
This calculator uses the average watt rating (100 Watts) for a Computer. You can input your Computer’s details to calculate the exact usage and cost of your device.
Hours used per day
Enter how many hours per day you estimate you run your Computer. If it is less than one hour use a decimal. For example, 30 minutes would be .5 and 15 minutes would be .25.
Power used (Watts)
Input the wattage of your Computer. If you are unsure enter the average wattage for a Computer: 68.
How many watts does a Computer use?
The average Computer uses 68 watts. Your devices wattage may be different depending on the brand, size, or other factors. You can generally find the wattage of your Computer in the user manual or on the device itself.
Your energy rate
Enter the price per kilowatt-hour (kWh) you pay for electricity. If you are unsure you can use the average rate per kWh in the US (10 cents) or find the kWh rate in your area here.
Which type of computer is more energy-efficient?
The amount of electricity usage depends on your equipment and how you use it. Laptops are considered more efficient than desktop computers because they operate for extended periods on battery power.
An ordinary desktop computer consumes more energy between 60 and 200 watts of electricity to operate normally. An uninterruptible power supply can significantly increase your desktop computer's energy consumption. Yet, it is essential to avoid system failures and other severe problems during power outages.
On the other hand, an average laptop draws between 20 and 50 watts of power. This amount can be decreased by switching laptops into power-saving mode, which uses energy more effectively. In power save mode, a dimmed screen scaled back functions, and other techniques to save energy may be included.
A desktop and a laptop's power consumption drops to around a third when in standby mode. This increases your home's "vampire draw," as it were. The monitor uses 15% less energy when it is in standby mode. Naturally, the monitor does not require any power if it is entirely turned off.
Computer Wattage
Computer energy usage can vary, but typical ranges lie between 15 and 300 watts per hour.
Laptops are energy-efficient and use less energy than earlier systems with complicated operating systems and heavy hardware. On average, you should anticipate tablets using between 20 to 50 watts of power, similar to how a standard laptop operates.
Desktop computers use more power and can operate between 60 and 200 watts. Only the tower will consume that much power; the monitor will use an extra 20–60 watts. Due to the massive variety of models, the energy range on desktop computers is broad.
Commonly, gaming desktop with a huge monitor and powerful hardware consumes the most energy. In contrast, a smaller, more basic desktop solely utilizes word processing software will consume the least.
Energy-Efficient Computers
Many people spend at least one day a week working from home. Working from home reduces energy use and commuting time. Still, unless you utilize energy-efficient office supplies, it could raise your home energy costs.
For some people, speed and power are the primary considerations for purchasing a new computer. However, the computer's energy-efficient structure is becoming more significant for a growing population. Here is a list of Energy-Efficient computers.
Dell Studio Hybrid
The Studio Hybrid is the greenest consumer desktop offered by Dell, and it has earned certifications from Energy Star and EPEAT. The Studio Hybrid receives EPEAT's highest rating of gold. It satisfies Energy Star's 4.0 green computing standards thanks to its 87 percent efficient power supply.
Dell OptiPlex
Professionals might consider Dell's OptiPlex range when seeking a scalable, extendable desktop. The OptiPlex is an energy-efficient workhorse; it also has an EPEAT Gold rating and complies with Energy Star 4.0. In the most recent EPA Fortune 500 Green Power Challenge, the Environmental Protection Agency (EPA) places Dell in the top five.
Lenovo ThinkCentre M58 / M58p
ThinkCentre desktops have received the EPEAT gold grade and are Energy Star 4.0 certified. Systems that use their management power capabilities can reduce energy usage by 69%.
According to Lenovo, energy conservation results in an annual electricity bill savings of $40. Not only is money saved, but CO2 emissions are also decreased.
Apple 17-inch MacBook Pro
Look into Apple's 17-inch MacBook Pro if you're looking for something compact, glossy, and environmentally friendly. This laptop offers gold EPEAT certification and Energy Star 5.0 compliance.
When it comes to minimizing environmental effects, the MacBook excels. It utilizes 35% less consumer packaging than its predecessor and is made of recyclable materials like glass and aluminum. It also lacks brominated flame retardants, PVC, mercury, and arsenic.
Tips for Saving Energy When Using a Computer
When the system isn't used for several hours, unplug it and turn it off. You can also Switch off the loudspeakers and printer if you are not using them. If you aren't currently using the PC, turn the screen off. If you won't use your PC for more than 30 minutes, turn it off or put it in standby mode.
