Cleaner Air for Future Generations

In 1998, the Ontario Medical Association declared air pollution a public health crisis in Ontario with coal-fired power plants being major contributors to the smog problem.

The Province committed to phasing out coal-fired generation in 2002, and the development of wind energy helped Ontario meet that goal in 2014. Today, wind turbines are harnessing wind across the Province and generating clean, homegrown energy without harmful emissions.

Sources: Emissions offset calculations use annual electricity production for the Henvey Inlet Wind (HIW) project compared to emission rates from the former Nanticoke coal plant as indicated in the Ministry of Energy’s report Coal Fired Electricity Generation in Ontario. The HIW annual electricity production estimate was updated in December 2017. Car comparison assumes typical passenger vehicles produce 4.7 metric tons of CO2 per year per U.S. Environmental Protection Agency. Water conserved compared to coal-fired generation assumes 2,048 litres/MWh per American Wind Energy Association. People supplied figure based on Environment Canada’s 2011 Municipal Water Use Report with 225 litres/day Ontario per capita water consumption.
