Wind power is unreliable, expensive and doesn’t result in lower C02 emmissions. Why is Ontario still rushing ahead with it?

In October 2007, the Ontario Power Authority (OPA) — the government’s own agency, tasked with planning Ontario’s power system and now entering into long-term contracts with renewable energy producers — published its Integrated Power System Plan, where it analyzed a “high wind power” scenario for the province, and concluded: “Since wind generation has an effective capacity of 20% compared to 73% for hydroelectric generation, additional generation capacity with better load-following characteristics would need to be installed.

“This needed capacity will likely have to be obtained by installing additional gas-fired generation. Thus, in addition to incurring further capital costs for the gas generation installation, higher gas usage would be expected to make up for the reduced amount of renewable energy from wind compared to that from hydroelectric generation or this alternative. Therefore, this alternative would result in higher greenhouse gas emissions.” The OPA concluded: “Wind and solar power will never be more than a niche supplier of power in Ontario.”
