The UK government has asked its people to delete old emails to play their part in not wasting water as the current drought situation has been defined as a “nationally significant incident”. Old emails, photos stored in data clouds require vast data centers and they consume large amounts of water to keep cool.The advice was issued as Britain endures its fourth heatwave of the summer. Five areas of England are currently officially in drought, with six more in ‘prolonged dry weather’.“The current situation is nationally significant, and we are calling on everyone to play their part and help reduce the pressure on our water environment,” Helen Wakeham, the Environment Agency’s director of water, said.“We are grateful to the public for following the restrictions, where in place, to conserve water in these dry conditions. “Simple, everyday choices – such as turning off a tap or deleting old emails – also really helps the collective effort to reduce demand and help preserve the health of our rivers and wildlife.”
