As the sale is ending soon, you have a narrow window to grab devices that'll actually pay for themselves through energy savings. If you see something you like, don't wait to snag it.

At just $20, this is the easiest entry point for energy monitoring and control. Three individually controlled smart outlets plus three USB ports mean you can identify which devices are energy hogs and cut power on a schedule. Phantom drain from chargers, entertainment systems, and office equipment can account for a surprising portion of your energy use, and this eliminates it automatically. Set timers so devices shut off when you don't need them, and manage everything through voice control with Alexa or Google Assistant.
This power strip gives you individual control over six outlets plus energy monitoring for each one, so you can identify which devices are quietly running up your bill. Phantom power drain from devices in standby mode adds up faster than you'd think, and this lets you eliminate it without unplugging everything manually. The built-in surge protection shields your electronics while the USB ports charge devices efficiently. Voice control through Alexa or Google Assistant means you can cut power to entire setups with a single command.
The Amazon Smart Thermostat automatically adjusts heating and cooling based on your schedule, cutting energy waste when you're asleep or away. It learns your patterns and makes changes without you thinking about it, which is where the real savings happen. Works with Alexa for voice control and integrates with Ring for smarter automation. Plus, many utility companies offer rebates on smart thermostats, potentially covering a significant chunk of the cost.
LED bulbs already use a fraction of the energy compared to traditional bulbs, but smart control takes it further by ensuring lights are never left on unnecessarily. These bulbs let you schedule lighting around your actual routines and automate everything through the app. Set schedules that turn off lights in empty rooms automatically or dim them during movies — simple changes that reduce consumption without you having to remember. Each bulb uses just 9.5 watts while offering full brightness and millions of colors.
Air fryers use significantly less energy than conventional ovens — they preheat faster, cook quicker, and don't heat up your entire kitchen, which means your AC isn't working overtime in warmer months. This 5-quart model handles everything from frozen fries to full chicken dinners using superheated air circulation. The compact design saves counter space, and for everyday cooking, it's one of the most efficient kitchen tools you can own. It's the kind of swap that makes a noticeable difference on your energy bill.
