Smart plugs are marketed as a simple way to cut energy costs and add convenience, but do they actually deliver savings? The answer, according to electricians, is more nuanced than you might think. While not a guaranteed windfall, strategically used smart plugs can lower your electric bill by addressing a key source of hidden energy waste: phantom power draw.
What is Phantom Power, and Why Does It Matter?
Many electronics continue to consume electricity even when switched off – a phenomenon known as “phantom load” or “vampire power.” This includes devices like TVs, game consoles, chargers, and even appliances in standby mode. Over time, this seemingly small drain adds up.
According to Ben Kolo, an electrician and franchise owner at Mr. Electric in Central Iowa, “Smart plugs help homeowners control phantom energy use by allowing control over when appliances draw power.” This means you can remotely switch off devices completely, preventing them from silently draining energy.
How Much Can You Actually Save?
The savings from smart plugs are modest, but consistent. Kolo estimates that the average homeowner can save between $20 and $60 per year by using them effectively. This figure depends on your energy habits, the size of your home, and the number of devices connected.
The key is not just having smart plugs but using them on devices that frequently draw phantom power. Plugging a seldom-used lamp into a smart plug won’t make much difference, but controlling a TV or gaming console that’s often left on standby can add up over time.
Beyond Smart Plugs: Other Energy-Saving Upgrades
Smart plugs are just one piece of the puzzle. Other smart home devices can significantly reduce energy consumption:
- Smart thermostats: These can save around $150 per year by optimizing HVAC usage.
- Smart lighting: LED bulbs paired with smart controls reduce energy waste and extend bulb life.
- Smart power strips: Similar to plugs, these cut power to multiple devices at once.
- Smart appliances: Energy Star-certified smart refrigerators, washers, and dryers use power efficiently.
The Bottom Line
Smart plugs aren’t a magic bullet, but they’re a cost-effective way to reduce energy waste, especially from devices that draw phantom power. Combined with other smart home upgrades, they can contribute to noticeable savings on your electric bill over the long term.
