Does Leaving the TV On Waste Electricity?

With the rise of energy-conscious consumers and the increasing costs of electricity, many are questioning the energy consumption of their household appliances.

One of the most commonly used devices in homes, the television, has come under scrutiny.

Does leaving it on waste electricity?

Let’s delve into this topic.


Do TVs Use Electricity When Turned Off?

Yes, they do.

Modern televisions come with a standby mode, which allows them to turn on quickly.

While in this mode, they still consume power, albeit a small amount.

This is often referred to as “phantom” or “vampire” power.

Over time, this can add up, especially if you have multiple TVs or other devices in standby mode.

How Much Electricity is Wasted by Leaving TV On?

Leaving a TV on for a full day can cost between 4 cents and 42 cents in electricity, with the average being 21 cents.

While this might seem insignificant, consider the cumulative cost over a year, especially if you have the habit of leaving your TV on when not in use.

Does Leaving the TV On Increase Electricity Bill?


The longer your TV stays on, the more electricity it consumes.

If you leave your TV on for extended periods, especially when not watching, you’re incurring unnecessary costs.

This is even more pronounced with larger TVs or those with higher resolutions, which generally consume more power.

How Many Watts Does a TV Use When Off?

While in standby mode, modern TVs consume between 0.5W to 3W.

This translates to costs between $0.66 and $3.94 per year if left in standby mode 24/7.

Do TVs Use a Lot of Electricity?

The electricity consumption of a TV depends on its size, type, and usage.

For instance, a 19-inch TV costs around $4.86 per year to run, while a 75-inch TV can cost up to $30.50 annually.

The resolution also plays a role.

A 4K TV, for example, costs around $22.73 per year, while a 720p TV costs about $6.50.

How Much Energy Does It Waste When I Sleep with My TV?

If you sleep for about 8 hours with your TV on, you’re looking at an additional cost of around 6 to 17 cents per night, depending on the TV’s size and type.

Over a year, this can add up to a significant amount.
