Earth Hour energy reduction 'negligible,' says city
Demand dropped by roughly 0.5% this year
The results are in from Calgary's Earth Hour but according to Enmax, the drop in energy demand was slight.
This year, energy consumption decreased by 0.5 per cent during the event, which took place Saturday from 8:30 p.m. to 9:30 p.m. in cities across the world.
That's similar to the city's historically low reduction in energy use during Earth Hour.
However, Enmax says it's important to look at the breakdown of electricity use in Calgary when analyzing Earth Hour numbers.
The amount of electricity used in Calgary for residential purposes accounts for only 30 per cent of the total use.
The remaining 70 per cent is used by commercial and industrial purposes and this discrepancy is what Enmax says is a large factor in the Calgary's typically low results during the event.
