Environmental Defence has a nice take-down of John LaForet and the gang at Wind Concerns Ontario. Below is my favourite bit, because it answers a question that has bothered me for awhile:
A big part of the anti-wind activists’ argument regarding viability is that the wind does not blow all the time – the power is intermittent. While this is true, the fact that wind power is part of an overall electricity system connected to multiple wind projects in different places, other electricity sources, and other jurisdictions who can trade electricity means that intermittency can be planned for and dealt with. Indeed, it is being successfully dealt with in countries likeDenmark, Germany, and Spain which already have much higher levels of wind power on their grids than Ontario does.
Digging deeper, anti-wind activists claim that wind power must have polluting electricity sources as backup, which just isn't true. Even if it were, it's bizarre to argue for dropping the clean part of the mix, leaving only the dirty part. The reality is that every megawatt hour of wind power delivered to the grid is a megawatt hour that does not have to come from someplace else, clean or otherwise.
At about 2 per cent of Ontario’s electricity output by fuel type,18 wind’s intermittency is currently easily dealt with by other sources. Hydro, for example, accounts for about 20 per cent and can be used as a type of storage, drawing down water levels when wind is low and letting them build up when it is strong. Ontario could also explore pumped storage at hydro facilities, using wind power during strong wind periods to pump water back behind dams to release for power later.19 With a better tie-in to the hydro-rich Quebec grid and more electricity trading with that province, the wind-hydro synergy could improve even more. Manitoba, for example, just signed a $4 billion deal with Minnesota to trade wind and hydro power.20
Finally, anti-wind activists allege that wind power isn’t viable because it is too expensive. It must be pointed out that if cost is their concern, then they should be arguing against nuclear power, currently Ontario’s largest and most expensive source of power, but we rarely hear this from them.
On a somewhat related note, this was a clever prank. Here's the Facebook page.
