Privatisation of the UK electricity system is being held up in Canada as a prime example of how free competition benefits wind power. Tom Adams of Toronto based Energy Probe said recently: "Although ecology was the last thing on Margaret Thatcher's mind, the UK's power privatisation has been a stunning environmental winner. Before Thatcher's privatisation, the UK power monopoly relied on coal and nuclear and was justifiably dubbed one of Europe's worst polluters." He continued: "Now, coal use is plummeting, replaced mostly by new, highly efficient natural-gas fired generators. Co-generation and wind power, stalled in Ontario, are surging there."
