Guelph Hydro says residents in Rockwood and the Royal City cut energy consumption by 1 megawatt Saturday night as part of Earth Hour.
That equates to about 350 homes being taken off the grid for one hour.
It’s a marked decline in participation. Last year just over two megawatts were saved. The year before, it was 1.7 megawatts.
Each year, people around the world are asked to cut electricity use for one hour.
Meanwhile, Toronto Hydro is reporting similar results in that city.
Electricity demand was 77 megawatts lower than a typical Saturday in March, but last year the drop was 89 megawatts.
However, a Toronto Hydro spokesperson says residents are using less power overall, so the drop in participation during this year’s event doesn’t mean enthusiasm for the movement is waning,
