Recent research highlights that datacentres now consume approximately 6% of total electricity supply in both the UK and US, raising urgent environmental questions. Letters to The Guardian from readers Gill Davidson and Robert Harrison propose practical measures—from deleting unnecessary digital files to repurposing waste heat—to mitigate the growing energy footprint of data storage.

The rapid expansion of datacentre infrastructure, driven by surging demand for cloud computing, streaming, and artificial intelligence, is placing unprecedented strain on electricity grids. According to research published earlier this month, datacentres account for roughly 6% of electricity consumption in the UK and US—a share that continues to climb as digital activity intensifies.
In a recent letter to The Guardian, reader Gill Davidson suggested that individuals can contribute to easing the demand by simply deleting photos and other files from their smartphones. “By deleting photos from our phones, we can ease demand for data storage and the huge amount of electricity it uses,” Davidson wrote, highlighting the cumulative impact of personal digital habits.
Another correspondent, Robert Harrison, offered a different angle: the waste heat generated by datacentres could be repurposed. Harrison proposed capturing and redirecting that thermal output for heating buildings, potentially offsetting some of the energy costs. Such approaches could help address the environmental cost associated with the massive electricity consumption of datacentres, which has become a “concerning issue,” as noted in the letters.
The debate comes amid broader scrutiny of the tech sector’s energy use, with regulators and policymakers increasingly focused on sustainability targets. While datacentres enable modern digital life, their environmental toll—including carbon emissions from fossil-fuel-powered grids—has drawn criticism from environmental groups and consumers alike.

Key Highlights
- Electricity consumption: Datacentres now account for roughly 6% of the total electricity supply in both the UK and US, according to recent research.
- Individual action: Gill Davidson suggests that deleting unnecessary photos and files from personal devices could help reduce the demand for data storage and the associated electricity usage.
- Waste heat repurposing: Robert Harrison advocates for capturing waste heat from datacentres and using it for heating, potentially lowering overall energy needs and environmental impact.
- Growing concern: The increasing energy intensity of datacentres is flagged as a worrying trend, given its environmental cost and the rapid growth of digital services.
- Policy implications: The letters underscore the need for both consumer behavioral changes and technological innovations to mitigate the sector’s energy footprint, which may attract further regulatory attention.

Expert Insights
The letters reflect a growing awareness that the convenience of digital storage comes with significant environmental trade-offs. The 6% share of electricity consumption attributed to datacentres is notable, particularly as that figure is projected to rise with the expansion of AI workloads and streaming services. Without efficiency improvements, the sector could become a major contributor to grid stress and carbon emissions.
While individual actions like deleting files may have a modest impact at scale, the more substantial gains are likely to come from infrastructure improvements. Repurposing waste heat, for example, could provide a dual benefit: reducing the need for separate heating systems in nearby buildings while lowering the overall energy intensity of datacentre operations. However, such solutions require upfront investment in heat capture and distribution networks.
From an investment perspective, companies that develop energy-efficient cooling systems, heat recovery technologies, or software for storage optimization may see increased demand. Meanwhile, datacentre operators face mounting pressure to disclose and reduce their carbon footprint, which could influence site selection and power purchase agreements. Regulators in the UK and US may consider tighter efficiency standards or incentives for waste heat utilization in the coming years. As the digital economy expands, the cost of data storage—both financial and environmental—will remain a key topic for industry stakeholders and policymakers alike.
