One of the driving forces behind home automation is improved energy efficiency. Even the most shrewd person’s home has leaks and inefficiencies that need to be plugged and fixed. Fortunately, there are devices out there that make it easy to do so.
Note: In most cases, energy efficiency is an investment — short-term expenses for long-term returns. Some of these offer immediate savings, but others may take months or years to recoup. Keep that in mind!
1. Turn Off Plugged-In Devices Overnight
Think about all of the devices and appliances that are currently plugged into an outlet at your home. You probably don’t worry about them much because they’re switched off and therefore aren’t using any power, right? Well, not exactly.
Even when electronic devices are shut off, they still have something called standby power. The truth is, when you turn a device off, you’re only turning off its primary function. Most devices actually have secondary functions that still run even when the primary function is off.
For example, some devices are slow to turn on if they start from a zero energy state, so these devices keep a small electrical current which allows for “instantly” turning on. Another example is when a device has a receiver that needs constant power in order to respond to things like remote controls.
Mr. Coffee Smart Wifi-Enabled WeMo 10-Cup Optimal Brew Coffeemaker, BVMC-PSTX91WE
Schedule or adjust brew time and setup reminders so coffee is fresh and hot whenever you want it using the Free WeMo App from your smart device Price: $124.99
Regular household devices that consume standby power can include, but aren’t limited to, the following: televisions, computers, microwaves, media centers, cable boxes, modems, routers, coffee makers, slow cookers, rice cookers, chargers and charging stations, and anything with an always-on display (such as a digital clock).
Roughly speaking, every 1W that a device consumes in standby mode translates into 9 kWh per year. Standby power usage per device can range from 1W to 15W depending on the device’s age and features. As such, plugging this leak could save you between $50 and $100 per year.

Turn appliances and electronics on or off from anywhere. Never worry if you left the iron, coffeemaker or hair straightener on. Turn on the nightlight for your little ones! Price: $38.99
The easiest way to do this would be to use smart plugs (also known as smart outlets). Smart plugs can be turned on/off from your smartphone, but more importantly, they can be put on a timed schedule, allowing you to automatically shut off standby power draw on devices overnight.
Have you ever left home for work only to remember that you forgot to turn off your TV, your lights, or even your air conditioner? Most of time, you can’t just rush home to turn them off manually, so you just have to suck it up and eat the costs of wasted energy.
This is an issue that could be solved with one or two smart home devices. As mentioned above, if your TV or air conditioner was connected to a smart plug, you could just shut the plug off with your smartphone and be done with it. But there are some other solutions that are more elegant.
If GPS-tracking is something you’d rather avoid, you could opt for something like a motion sensor instead, which would detect your physical arrival at home and react accordingly. Note that this route may require investing in a smart hub that’s compatible with said motion sensor.
As an aside, you could also tie this in with home security. With the right devices, you could set up wireless home surveillance cameras that automatically start capturing footage when you leave home and stop when you come back. No need to waste energy recording 24/7 during those times you’re already at home.
3. Measure Energy Used by Devices
In personal finance, there’s one core principle that acts as the foundation of all things related to money: if you want to fix your money problems, the first thing you have to do is figure out where all of your money is going. (This is especially true when struggling to get out of debt.)
The same principle applies to energy efficiency: if you want to cut back on energy consumption and really make a difference, the most important thing you can do is measure and track which devices and appliances are using the most energy. You’ve never actually measured your energy usage, have you? Most people haven’t.
Belkin Conserve Insight Energy Use Monitor (F7C005Q)
See how much different devices cost to use on a yearly or monthly basis Price: $29.90
The Belkin Insight Energy Use Monitor plugs right into any outlet, allowing you to plug devices into the monitor’s outlet instead of the actual wall outlet. The monitor will then track energy usage and predict what those devices will cost you over time.
Enerwave ZW15RM Z-wave Wireless Lighting Control Duplex Tamper Resistant Wall Receptacle With Smart Meter Energy Monitor, White
Replaces standard switch to enable wireless ON/OFF operations on lights, fans and small appliances Price: $43.99
Another option is the Enerwave Smart Meter Energy Monitor, which replaces the wall outlet altogether. Not only does it monitor energy usage, but it can also be turned on/off remotely. It’s also more compact than the Belkin, which is aesthetically nicer to the eyes.
Once you know which devices are consuming the most energy, you can then decide what to do about it. For instance, maybe you’ll realize that your incandescent bulbs are costing you too much and finally upgrade to LED bulbs (a change that comes with many security benefits).
4. Upgrade to Energy-Efficient Appliances
Let’s say you’ve determined that a certain device or appliance is being an energy hog. You’ve done your best to eliminate standby power waste, and you’re only using it when you need to, but it’s still sucking electricity like crazy. What then?
In that case, it’s time to upgrade to something more modern.
When upgrading, you may even want to consider something smart instead of something traditional.
For example, smart refrigerators are growing in popularity and it’s not hard to see why. Compared to the usual fare, they have better controls for temperature and humidity for different compartments, they can improve shelf life of produce, are energy-efficient, and can even interact with your smartphone.
The Samsung 4-Door Smart Refrigerator is one of the better offerings available today. Not only does it do all of the above, but all of its lighting is done with LEDs and, overall, greatly surpasses ENERGY STAR requirements across the board.
Solar panels are an obvious choice for anyone who wants to improve home efficiency. They may take a while to pay for themselves, but it’s undeniable that they do pay for themselves — especially once you factor in long-term increases in fossil fuel costs. In particular, solar is good for heating air and water.
Fortunately, there are companies that can help you get started. They’ll step you through the process and make sure you don’t make any catastrophic errors, such as ensuring your roof can withstand the weight of solar panels and calculating overall costs.
If you want to try it out but without the huge commitment, you could wet your feet with these solar-powered household gadgets instead. Since they’re powered solely by the sun, you can still end up saving on your energy bill.
6. Smart Thermostats Pay for Themselves
We can’t forget about smart thermostats. In fact, one might even argue that the smart home movement never would’ve taken off if it weren’t for the sudden boost in popularity of the Nest Thermostat a few years back.
In the end, it doesn’t really matter which one you get as long as you get one that works with your home’s climate control. A smart thermostat can save 10-15% on heating and cooling costs, which means $100-$150 per year for the average home. These things pay for themselves in no time.
If you want to save even more money in the winter, wear layers and set the temperature as low as comfortable. Then help fend off the cold weather with some of these warm household devices and gadgets.
7. Don’t Forget About Smart Water Usage
Water usually doesn’t fall under the same heading as energy, but if you’re the kind of person who’s trying to cut back on energy usage (for whatever reason), then you probably want to cut back on water usage as well.
The good news is that there are smart devices for this, too.
For example, we recently covered reasons why you might want smart faucets in your kitchen and bathrooms. Long story short, smart faucets are easier to control, less prone to spreading germs, and more efficient with water — and that’s not even mentioning the coolness factor.
