According to a campaign group that has criticized government net zero policies, smart meters may become the next step in "snooping" on household energy consumption. Ministers are discussing the possibility of sharing household energy usage with third parties who can assist customers in finding cheaper energy deals and lower carbon tariffs from competitors. 

The European watchdog responsible for protecting personal data has been concerned that high-tech monitors that track households' energy use are likely to pose a major privacy concern. A recent report released by the European Data Protection Supervisor (EDPS) states that smart meters, which must be installed in every home in the UK by the year 2021, will be used not only to monitor energy consumption but also to track a great deal more data. 

According to the EDPS, "while the widespread rollout of smart meters will bring some substantial benefits, it will also provide us with the opportunity to collect huge amounts of personal information." Smart meters have been claimed to be a means of spying on homes by net zero campaigners. A privacy dispute has broken out in response to government proposals that will allow energy companies to harvest household smart meter data to promote net zero energy. 

In the UK, the Telegraph newspaper reports that the government is consulting on the idea of letting consumers share their energy usage with third parties who can direct them to lower-cost deals and lower carbon tariffs from competing suppliers. The Telegraph quoted Neil Record, the former economist for the Bank of England and currently chairman of Net Zero Watch, as saying that smart meters could potentially have serious privacy implications, which he expressed concerns to the paper. 

According to him, energy companies collect a large amount of consumer information, which is why he advised the public to remain vigilant about the increasing number of external entities getting access to household information. Further, Record explained that, once these measures are authorized, the public would be able to view detailed details of the activities of households in real-time. 

The record even stated that the public might not fully comprehend the extent to which the data is being shared and the possible consequences of this access. Nick Hunn, founder of the wireless technology consulting firm WiFore, also commented on the matter, highlighting the original intent behind the smart meter rollout, He noted that the initiative was designed to enable consumers to access their energy usage data, thereby empowering them to make informed decisions regarding energy consumption and associated costs. Getting to net zero targets will be impossible without smart meters. 

They allow energy companies to get real-time data on how much energy they are using and can be used to manage demand as needed. Using smart meters, for instance, households will be rewarded for cutting energy use during peak hours, thereby reducing the need for the construction of new gas-fired power plants. Energy firms can also offer free electricity to households when wind energy is in abundance. Using smart meters as a means of controlling household energy usage, the Government has ambitions to install them in three-quarters of all households by the end of 2025, at the cost of £13.5 billion. 

A recent study by WiFore, which is a wireless technology consulting firm, revealed that approximately four million devices are broken in homes. According to Nick Hunn, who is the founder of the firm: "This is essentially what was intended at the beginning of the rollout of smart meters: that consumers would be able to see what energy data was affecting them so that they could make rational decisions about how much they were spending and how much they were using."
