Summers in Toronto can be kind of, well, hot. With lights, machinery, and air conditioning at their yearly peak, the strain on the city’s power-system can be enormous.

To reduce the summer strain on the city’s electrical system, Toronto Hydro-Electric System Ltd. is offering consumers a financial incentive to conserve power.

If Toronto power consumers can reduce their summer power consumption by 10% from the previous summer’s bill, Toronto Hydro-Electric will knock 10% off of autumn’s electricity bill. Using fans instead of air conditioning, even for part of the day, can put a 10% reduction well within reach of most consumers. A financial incentive to conserve is hard to ignore.
