The hidden energy cost of smart homes

Controlling our homes with the tap of an app may have hidden energy costs
Light globes that change colour with the tap of an app, coffee machines you can talk to, and ovens that know exactly how long to cook your food: our homes are getting smart. These devices, just a few examples of what is known as “the internet of things” (or IOT), have been called the “next great disruptor” and “the second digital revolution”.
One of the great hopes of this revolution is that it will help households save energy. Sensors can turn off lights and appliances when not in use, or turn the heating down when people go to bed. Smartphone apps can provide households with more insight into the energy use of their appliances.
While estimates vary widely, industry proponents suggest that emerging connected home technologies could help households reduce their energy bills by 10-25%. Such claims are largely speculative given the absence of robust “before and after” research.
Social research from Australia and the UK is revealing ways in which IOT might also increase energy demand. We have identified three “hidden” energy impacts which are rarely considered in IOT research or energy-saving predictions.
