Energy-efficiency is more than a buzzword, it is a combination of practices and the use of products that use a minimal amount of energy to complete a task. Unfortunately, no matter how energy-efficient the appliance or device, if it is plugged into an electrical outlet, it may be costing a homeowner money.
This wasted energy is technically called “standby power” but is commonly referred to as “vampire electricity”.
According to numerous studies, vampire electricity accounts up to 10% of all the energy consumed within the household. Based on these calculations in 2011, the amount of energy wasted by vampire electricity in the United States was higher than the total energy consumption of both Greece & Switzerland combined. Many appliances and devices are notorious for vampire electricity. These devices include:
- Cellphone chargers
- Handheld video game chargers
- Laptop chargers
- AC Adapters ( anything that charges a battery)
- VCSs/DVD players/Cable Boxes
- Video Game Consoles
- Kitchen appliances (toasters, coffee markers, etc.)
- Cordless telephones
- Any device that can be woken up by a remote control
