Wind Power Isn't Perfect, But It's a Hell of a Lot Better than the Alternatives

If we were to stick with our coal phase-out strategy without wind, we would need to burn more natural gas. The reality is that when the wind blows it gives us the opportunity to burn less natural gas when it's being used to displace coal. This is partially why greenhouse-gas emissions associated with electricity generation in Ontario have fallen by two-thirds since 2003.
