A 12-week smart meter trial in Birmingham, England, has saved more than 10 tones of CO2 emissions, with some homes reducing electricity costs by £35 per month.
The Digital Birmingham and Family Housing Association installed DEHEMS (Digital Environment Home Energy Management System) smart meters in 49 homes in Lozells, Handsworth, and Edgbaston.
Besides the DEHEMS meter, participants received ‘Green Doctor’ training designed for changing their behavior and encouraging efficient energy consumption.
Over the trial period, the number of people unplugging chargers from the mains, always switching off lights when leaving a room, never leaving appliances on standby and boiling just enough water for one person when using a kettle had doubled on average.
Trial participant Jean Allison from Handsworth says the project has changed her behavior for good and considerably reduced her bill.
