As the world becomes increasingly conscious of energy consumption and its impact on the environment, many of us are looking for ways to reduce our carbon footprint and lower our utility bills. One popular tip that’s been circulating is to unplug appliances and electronics when not in use to save energy and money. But does this really make a difference? In this article, we’ll delve into the world of standby power, also known as vampire power, and explore the truth behind the claim that unplugging things can save you money.
What is Standby Power?
Standby power, also known as vampire power or standby load, refers to the energy consumed by appliances and electronics when they’re turned off but still plugged in. This can include everything from TVs and computers to phone chargers and kitchen appliances. Even when these devices are turned off, they can still draw a small amount of power from the grid, which can add up over time.
How Much Energy Does Standby Power Consume?
The amount of energy consumed by standby power can vary widely depending on the device and its efficiency. Some devices, like TVs and computers, can consume up to 10-20 watts of power when turned off but still plugged in. Others, like phone chargers and kitchen appliances, may only consume a fraction of a watt.
According to the U.S. Department of Energy, the average American home has around 20-30 devices that continue to draw power when turned off. This can add up to around 10% of a home’s total energy consumption, which can translate to around $100-200 per year in wasted energy costs.
Does Unplugging Things Really Save Money?
So, does unplugging things really save money? The answer is yes, but the amount of money you can save depends on several factors, including:
- The type and number of devices you unplug
- The efficiency of those devices
- Your local energy rates
- Your overall energy consumption habits

How to Save Money by Unplugging Things
If you’re looking to save money by unplugging things, here are a few tips to keep in mind:
- Unplug devices when not in use for extended periods: If you’re going to be away from home for an extended period, unplug your devices to save energy and money.
- Use power strips: Power strips can make it easy to unplug multiple devices at once, which can be especially useful for home entertainment systems or computer setups.
- Look for devices with low standby power consumption: When shopping for new devices, look for ones with low standby power consumption to minimize energy waste.
- Adjust your energy consumption habits: In addition to unplugging devices, adjust your energy consumption habits by turning off lights, using energy-efficient light bulbs, and adjusting your thermostat.
Calculating Your Savings
To calculate your potential savings from unplugging devices, you can use the following formula:
- Identify the devices you want to unplug and their standby power consumption (in watts)
- Multiply the standby power consumption by the number of hours the device is plugged in but not in use per day
- Multiply the result by the number of days per year
- Multiply the result by your local energy rate (in dollars per kilowatt-hour)
For example, let’s say you want to unplug your TV, which consumes 10 watts of power when turned off but still plugged in. You estimate that the TV is plugged in but not in use for around 8 hours per day, and you want to calculate your potential savings over the course of a year.
- 10 watts x 8 hours/day = 80 watt-hours/day
- 80 watt-hours/day x 365 days/year = 29,200 watt-hours/year
- 29,200 watt-hours/year x $0.12/kilowatt-hour = $35.04/year
In this example, unplugging your TV could save you around $35 per year.
Conclusion
Unplugging things can be a simple and effective way to save money on your energy bills, but it’s not a one-size-fits-all solution. By understanding which devices are worth unplugging and adjusting your energy consumption habits, you can make a real impact on your energy waste and your wallet. Remember to always look for devices with low standby power consumption, use power strips to make it easy to unplug multiple devices at once, and adjust your energy consumption habits to maximize your savings.
By taking these simple steps, you can join the ranks of the energy-conscious and start saving money today.
