What is phantom energy? The hidden electricity drain explained

The lights are off, the house is quiet and nothing seems to be running. But electricity is silently flowing through the plugs in your home. This hidden drain is known as phantom energy.
Also called vampire energy, the wasted electricity comes from leaving devices plugged in when they’re not in use. That could range from household items such as phone chargers and microwaves to TVs and gaming consoles.
This wasted electricity accounts for about 5% to 10% of home energy use, depending on factors like the age of the equipment, according to Alexis Abramson, dean of the Columbia Climate School.
“Phantom energy depends on … what kind of systems you have and how much they’ve improved over time,” said Abramson.
For example, televisions that are connected to the internet and have smart wake features that allow them to interact with phones and other devices can consume up to 40 watts of energy during the hours of the day that the TV would normally be off, according to Matt Malinowski, director of the buildings program at the American Council for an Energy-Efficient Economy. That’s almost 40 times as much as a regular television.
“The good news is there have been new, renewed efforts to tackle this,” said Malinowski.
He said advocates and manufacturers have come up with a voluntary agreement seeking to reduce the amount of energy smart televisions use when they’re in standby mode.
Phantom energy contributes to climate change because power drawn by unused devices can increase demand for electricity from sources that release planet-warming emissions. Aidan Charron, associate director of Global Earth Day, said that while the amount may seem small when a person looks at their individual utility bill, the environmental toll of phantom energy is significant when multiplied over homes across the country.
“Just take a little step of unplugging the things that you’re not using,” said Charron. “It will save you money and it’ll save emissions in the long run.”
What you can do
Some of the main culprits when it comes to draining energy are appliances that are constantly connected to electricity, such as those with a clock.
“Do you really need your microwave to tell you the time, or can you unplug your microwave when you’re not using it?” said Charron.
While unplugging devices may seem burdensome, it significantly contributes to reducing emissions.
Charron recommends starting with small steps like unplugging chargers for phones and other devices once the battery is fully charged. The next step is moving to other appliances such as unplugging an unused lamp.
If unplugging sounds too hard, regularly checking your settings and disabling any extra feature you’re not using that could be draining energy help, too. For example, smart televisions often have optional features that can be turned off so the television isn’t listening for signals from other devices while in standby mode.
“If you’re not using it, then you’re getting no benefit, yet you’re paying the price and increased the energy use,” said Malinowski.
How individual actions can make a difference
Individuals also tend to take more sustainable actions, such as unplugging devices, once they learn what they can do to decrease their household emissions efficiently. Those actions could contribute to reducing U.S. emissions by about 20% per year, which equals about 450 tons (408 metric tons) of carbon dioxide, according to Jonathan Gilligan, a professor of earth and environmental science at Vanderbilt University.
The choices individuals take in their daily lives all add up, Gilligan said, mainly because of how much the U.S. population contributes to direct greenhouse gas emissions.
“The question becomes, what can we do to try to address this?” said Gilligan. “Phantom power is one part of this.”
The more individuals decrease their footprint, the more likely it is that others will follow, too, and eventually, those actions may turn to societal norms, according to Gilligan, because individuals don’t want to feel like they’re being irresponsible.
“This is a place where psychologists find that this effect is real. If people see that other people are doing actions to reduce their greenhouse gas emissions, they want to do that” said Giligan.
When it comes to daily choices, individuals may think what they’re doing isn’t really making a big difference. But what they tend to overlook is how they influence others around them by choosing to live a more sustainable life.
The impact may be much stronger than a lot of people realize, Gilligan said.

Some major Australian towns still have poor phone reception—it’s threatening public safety

by James Meese, Amber Marshall, Holly Randell-Moon, Jenny Kennedy, Rowan Wilken, The Conversation
Australians rely on their phones and the internet for education, business, socializing and in emergencies. And as Optus’ recent Triple Zero outage highlights, the consequences of a network outage can be fatal.
But the problems go beyond Triple Zero. The latest annual report from the Telecommunications Industry Ombudsman, released earlier this week, shows a spike in complaints about network connection issues compared to last financial year. For example, there was a nearly 70% increase in complaints about “no phone or internet service.” Complaints about “poor mobile coverage” also increased more than 25%.
When it comes to connectivity problems, we often think about remote environments such as inland cattle stations or Indigenous communities in central and far north Australia. Or how language barriers, affordability and age might impact access.
However, across various research projects looking at digital inclusion, we have found a policy blind spot, where populations residing in certain suburban and regional areas have poorer connectivity outcomes than remote areas.
These people experience ongoing problems with network connection despite living in locations that look good on paper. This could be because of local infrastructure gaps or compounding social factors. We call this group “the missing middle.”
Until now, the absence of a clearly defined category has made it difficult to capture or report on their experiences systematically.
What is ‘digital inclusion?’
Digital inclusion is about ensuring all Australians, no matter who they are or where they live, have access to affordable, quality telecommunications and internet, and possess the skills necessary to benefit from these connections.
The issue is even more important as we face a changing climate, with telecommunications playing a crucial role in emergencies and during natural disasters.
Our research from 2023 on emergency preparedness with rural residents showed the importance of ongoing telecommunications connectivity—especially during emergencies.
People participate in online community forums by keeping each other informed about conditions and contacting emergency services such as Triple Zero if they need to during the disaster. Afterwards, they use the internet to apply for financial assistance online.
Of course, natural disasters do not discriminate. Recent cyclones, floods and bushfires have impacted urban areas, as well as the outer edges of cities and key regional centers.
A good location doesn’t equal good connectivity
These combined forces have ensured telecommunications policies consistently focus on access. But access is just one component of Australia’s connectivity needs.
Through various interviews, focus groups and fieldwork across urban, regional and rural Australia from 2021–24 we have found that location alone doesn’t determine how good connectivity is.
In fact, some remote areas fare better than outer regional areas when it comes to telecommunications connectivity. This indicates geography isn’t the only factor affecting people’s level of digital inclusion.
Instead, compounding factors are determining whether or not people are digitally included.
For example, some people may not have enough money to afford appropriate connectivity to meet basic needs, needing two SIM cards to manage two unreliable networks. Infrastructure investment can also be patchy. A major regional town might have excellent coverage, but satellite towns could have a much poorer experience.
Urban networks can also taper off before reaching new builds on the edge of cities. Other people may have simply purchased a house amid inhospitable terrain, which can impact whether satellite internet services such as Starlink can be installed.
Voices from the ‘missing middle’
Experiences of 5G mobile consumers in suburban and regional Victoria we spoke with in 2024 give us some sense of this “missing middle” population.
One participant from Gippsland said, “I can be in the main street of a main regional town and not have reception.”
Another participant said it was “less than ideal” that in the area between two towns “there’s still patches where we don’t get reception.” Echoing this, another participant said they felt it was reasonable to “expect to be able to drive from Gisborne to Kyneton [a distance of 30km] and not drop out on a phone call three times.”
These issues were not the sole preserve of those living in regional areas. Someone from a new housing development on the outskirts of Melbourne told us there was barely any mobile coverage in the area and said their phone was “just not usable.”
Dubbo is another example. While some major regional cities are well-connected, this major town in the central west of New South Wales is also part of the “missing middle.”
First Nations organizations there experienced slow and unreliable network connection. This impacted their capacity to service the area. Drops in coverage resulted in double handling of work. For example, land surveys would often need to be written by hand on site, then converted to digital forms back in a place with better connectivity.
A targeted approach
Lots of work has been done in recent years to improve connectivity across Australia.
Since the National Broadband Network (NBN) was completed in 2020, more fixed line services—where a connection is installed in the home (like an NBN box)—have been made available in rural towns.
The federal government’s flagship infrastructure projects—such as the Regional Connectivity Program and Mobile Blackspot Program—have also steadily improved digital inclusion in many locations over the last decade. Starlink and the NBN’s satellite internet service SkyMuster are new entrants, providing a new connectivity option for people who live in the right locations (and can afford it).
However, current policy approaches to patching up connectivity gaps minimize the scale of the missing middle.
This is the result of several factors. First, a failure to understand the different needs of the local and visitor populations who use digital services. Second, fragmentation across telecommunications options (NBN, mobile hotspotting and Starlink). Third, a need to account for overlapping disadvantages.
We need to look beyond location or access, and develop a robust account of the “missing middle.”
Doing so requires policymakers and researchers to focus on areas with mixed and complex connectivity needs. Importantly, this kind of shift will help policymakers target the needs of these Australian telecommunication consumers.
