Smart meters — digital devices that monitor electricity usage in real-time — are being installed in homes worldwide under the banner of energy efficiency. What utility companies do not advertise is the granularity of data these devices collect and the surveillance potential they enable.
A smart meter does not just record total energy consumption. It captures usage patterns at intervals as short as every few seconds — creating a detailed profile of household activity. Researchers have demonstrated that this data can reveal when you wake up, when you leave for work, what appliances you use, and even what television programs you watch.
“Smart meter data can infer occupancy patterns, sleeping habits, and daily routines with remarkable accuracy. This is not hypothetical — it has been demonstrated in multiple peer-reviewed studies.”
The data is transmitted wirelessly to utility companies, creating a permanent record of domestic activity. In the UK, smart meter data is accessible to energy companies, government agencies, and potentially third parties under various information-sharing agreements.
When combined with smart home devices, digital IDs, and financial tracking, smart meters complete the picture — there is no longer any space, public or private, that is free from surveillance.
