A recent study found that the majority of Wi-Fi smart thermostat owners are men – and they are usually the ones who end up programming the thermostat! This is according to a study conducted by the Energy and Resources Group at the University of California, Berkeley. The study explored the potential of using Wi-Fi smart thermostats to reduce energy use and found that men are more likely to use the programming functions than their female counterparts. This could be due to the fact that men tend to be more technologically savvy and are more likely to tinker with the settings on their thermostat. It could also be due to the fact that men are more likely to take ownership of household tasks such as controlling the temperature in the home. Whatever the reason, it's an interesting fact about Wi-Fi thermostats that could make potential shoppers smile. Source:
