Is wearable tech the next big thing in energy?
Smartphones and their apps have already been doing great things for users managing their energy, and it looks like smart watches and other wearable technologies could offer added benefits. Wearable tech opens up energy management opportunities at home, at the office, and elsewhere.

On September 9, Tim Cook unveiled the听, 鈥渢he most personal product鈥� Apple has ever made, says the company, 鈥渂ecause it鈥檚 the first one designed to be worn.鈥� The watch joins other products like bracelets from听听补苍诲听听in a category called 鈥渨earable technologies,鈥� or wearables.
Beyond decorating your wrist, these products are primarily worn to send, receive, and process information, through cellular networks, WiFi, Bluetooth, or鈥攗nique to Apple鈥檚 Watch鈥攏ear-field communications (NFC). The Apple Watch can monitor your heart rate, track your location (through an accelerometer, gyroscope, and GPS), and recognize your voice.
THE WEARABLE DIFFERENCE
Smartphones and their apps have already been doing great things for users managing their energy (and much more, including fitness), for example through connected thermostats, electric vehicle charging, solar panel output monitoring,听, and much more. So why would you wear Apple鈥檚 Watch when you have an iPhone? What extra value do wearables unlock that already isn鈥檛 accessible through other technologies?
First, wearable technologies can collect biological data, such as your heart rate and body temperature鈥攖hat a phone in your pocket cannot. These data sources can tell a more complete story about your physical state than data from your phone. Second, wearable technologies are less likely to be separated from the user. Unlike phones, most users will wear their Apple Watch in the shower or in bed. In other words, it鈥檚 always with you.
This connectedness between wearable tech and the wearer opens up at least three categories of energy management opportunities: at home, at the office, and personal.
ENERGY USE IN YOUR HOME
Wearable tech can help better match our homes鈥� energy use鈥攅specially heating and cooling鈥攖o our needs. For example,听听has a built-in motion sensor. It鈥檒l put your home鈥檚 HVAC system into an energy-saving 鈥渁way鈥� mode after a period of inactivity. But imagine how much energy could be saved if a device on your wrist signals your thermostat to go into 鈥渁way鈥� mode the moment you leave your home or neighborhood.

Similarly, programmable thermostats can be set to pre-condition your house so that it鈥檚 a comfortable temperature when you wake up and roll out of bed in the morning. Some smart thermostats even detect when you typically wake up during the week and create a fixed start-up time for your thermostat based on that. But wearing a device on your wrist鈥攚hich is either connected to an alarm to wake you up, or which detects your sleep cycles and learns when you鈥檙e likely to wake鈥攃an more accurately tailor your home鈥檚 pre-conditioning to match your actual wake-up time, rather than a weekday thermostat program set to the same time, on average, you鈥檙e likely to get up.
ENERGY USE IN YOUR OFFICE
Have you experienced working in a ridiculously frigid office in summer, because the building control system does not know how people feel? Or an overly hot office in the winter? Even an office that鈥檚 conditioned well to a target temperature could feel too hot and/or too cold (even at the same time!) given one person鈥檚 preferences vs. another.
Wearable technology can provide information like body temperature, heart rate, and respiration, giving a more complete picture of physical comfort. Voice recognition software could even detect when people are complaining about feeling too hot or cold.
Even more, wearable tech and other more personalized devices can help to condition the person, rather than the entire space鈥攊n fact, that鈥檚 the very principle behind heated seats and a听; it鈥檚 more efficient to make the person feel comfortable, rather than heat or cool the entire cabin. In an office setting, think of office chairs with heating elements, wristbands that cool your wrist like that from听, or vents that determine personal air flow like those from听.
Beyond the office, wearable tech can have other applications when out and about, too. At the product launch, Cook described how the Apple Watch can replace a hotel keycard to unlock your room as you approach the door. Similarly, your watch can connect to your hotel room鈥檚 thermostat, to delay room cooling until you have checked in. No energy is wasted cooling an empty room, while ensuring a guest鈥檚 room is comfortable as they enter.
A COMING ERA OF PERSONAL ENERGY PROFILES?
In a coming era when energy use becomes not just highly personalized, but attached in fact to individual people, it鈥檚 not hard to imagine developing personal energy profiles of our individual demand and consumption. And that could open the door to personal energy bills. Usually we bill our energy use to our energy-consuming assets鈥攅lectricity and natural gas billed monthly for our home, for example. But imagine if instead of assigning energy consumption to our assets we re-assigned that energy consumption to ourselves? Gone could be the arguments between roommates about how to equitably split the utility bill (one of the top sources of friction among roommates in places such as New York City).
Or what if wearable tech, in addition to sending personal information out to the systems around us, could also receive signals back to us, such as from your utility. Could wearable tech further open the door to a personal version of demand response? For example, similar to how utilities use demand response to cycle off air conditioners during times of exceptionally high peak demand in summer, could they instead signal a Wristify bracelet to cool a person instead of an AC unit cooling a whole house, or could your Apple Watch receive a signal from the utility asking you to have an ice-cold tea instead of turning up the AC at 4:00 p.m.?
PRIVACY VERSUS PERSONAL COMFORT
Many of the comfort-improving, energy-saving features above are enabled by more information about you being shared with computers. This of course opens up another set of issues around Big Brother watching and the privacy of potentially very personal information, who can 鈥渟ee鈥� that information, and how will they be allowed to use that info. Whether having the option to turn such data sharing on or off, or another solution such as anonymizing the data, the face remains that wearable tech could be another front line in the grid鈥檚 evolution toward more distributed energy resources. Those DERs could now include not just things like rooftop solar panels and batteries in your garage, but also wearable technologies and the people who wear them.
