I am aware of a few solar-PV installations at housing co-operatives in Ottawa, and one of my neighbours has a small installation on his roof. I think solar-PV is popular in Ontario in part due to the Ontario Power Authority’s Feed-In Tariff (FIT) Program, which also applies to on-shore wind, waterpower, renewable biomass, biogas and landfill gas electricity generating projects. The FIT Program is structured such that participants receive a fixed price for the electricity they produce of a 20-year contract period (http://fit.powerauthority.on.ca/fit-program).
I haven’t noticed any wind turbines in the Ottawa area, but I was recently in Kingston and could see the Wolfe Island wind farm. It’s the second largest wind farm in Canada from a capacity perspective, with a nameplate capacity of 197.8 MW and started operation in 2009 (http://www.transalta.com/facilities/plants-operation/wolfe-island).
