The summer of 2021 in Western Canada was one of the hottest on record. In the Canadian province of British Columbia alone, 59 weather stations registered their hottest temperatures ever on June 27. For those lucky enough to have air conditioners, keeping their homes cool during the heat dome was relatively easy. However, the comfort lasted only until the utility bills arrived. As a result of heatwaves around the world, global electricity demand increased by five per cent so far in 2021 and it is expected to continue to increase annually.
