D.C. and Maryland households are getting quietly drained by "standby" or "vampire" power, with a new analysis finding residents here among the hardest hit as the cost of always-on energy use climbs nationwide.
In a breakdown of state-level "one-week standby" costs, warranty firm Domestic & General found sharp year-over-year and multi-year jumps in several Mid-Atlantic markets, according to DC News Now. The study also surveyed more than 2,000 Americans on how much they know about "vampire" devices and which everyday habits keep standby use higher than it needs to be.
What the study shows
Domestic & General calculated that District households rack up about $161.32 in total one-week standby energy costs, while Maryland households land around $150.27. The firm found D.C.'s standby costs were roughly 76% higher than in 2020 and Maryland's had climbed about 61% over the same period. The analysis also flagged steep one-year spikes of roughly 29% for D.C. and 16.1% for Maryland, while other pricey one-week totals turned up in Hawaii ($267.69), California ($226.41) and Massachusetts ($211.39). Those figures roll typical idle draws from TVs, chargers, smart appliances and HVAC standby functions into a single "standby" metric, according to Domestic & General.
Why "vampire" power matters
"Vampire" or phantom loads are the low, constant trickle of electricity used by devices that are off or sitting in standby. Individually they look tiny. Together they are not: the U.S. Department of Energy estimates standby power makes up roughly 5% to 10% of residential energy use and can cost the average household about $100 a year. Earlier findings from the Natural Resources Defense Council have put the annual cost closer to $165 and warned that idle loads can be a meaningful slice of home electricity consumption. Taken together, those long-running findings highlight how cutting always-on draws can trim both energy bills and emissions, according to NRDC and the U.S. Department of Energy.
How to cut your standby drain
The study and energy officials point to some simple fixes that do not require a home renovation: unplug non-essential gear when you can, plug clusters of electronics into switchable power strips, buy ENERGY STAR appliances and pare back unnecessary HVAC runtime. Domestic & General also suggests cleaning filters and checking for air leaks so heating and cooling systems are not running longer than they have to. Small habits, like flipping a power strip off at night or replacing older chargers and power supplies, can add up to real savings over the course of a year, according to Domestic & General.
For D.C. and Maryland residents already juggling high rents and hefty utility bills, the extra cost of idle energy can feel like a convenience penalty, but it is also a relatively painless place to start cutting back. As DC News Now notes, many Americans still are not familiar with "vampire" devices, which means a few quick changes around the house could deliver fast, low-cost wins.
