Every cord that remains plugged into an outlet is pulling energy out. That’s what they are designed to do. It’s great when you need to use electronics or appliances, and when you need to turn the television on immediately, but this is what causes the leak in energy. While many devices have sleep or standby modes, they still continuously use electricity to perform updates, connect to remote servers and record data (especially in the modern world of apps and instant connections).
Example: TVs
The connectivity of modern technology is the main reason our devices leak energy. Even when the TV is off, it is still ready to receive signal from the remote to power on at any time.
Example: DVD Player
Your DVD is always “lying in wait” until its time to record the next show or run behind-the-scenes updates.
