It is still expensive, for one. Liddle put generating costs alone at nine to 11 cents per kilowatt-hour. This in a province where residential users pay a regulated price of five and 5.8 cents per kilowatt-hour, depending on use-though in recent months industrial power users have been paying market prices of eight to ten cents per kilowatt-hour for their power. It is also unreliable. Power production depends on how the winds blow: turbines turn off when wind speeds fall below four metres per second, or when they exceed 25; they produce the most power at wind speeds of 18 metres per second.

If the wind isn't blowing at peak times, the argument goes, then the wind turbines are not contributing to the power in the grid. However, if wind farms could store all the power they generate at off-peak times, during the night for example, and then control the way and time it is released, it would not only enhance the revenue streams they could receive, but also remove the intermittency claims. Now, a Canadian energy management firm claims to be able to do just that. EPOD International has secured two pilot projects with wind power developers in Canada and the US to test their proprietary energy storage system, the EMT.
But world energy resources are adequate to meet this sustained growth trend because global oil reserves today exceed the cumulative projected production to 2030, IEA said. This optimistic outlook, however, is based on a reference scenario that IEA describes as "unsustainable." Under that reference scenario, primary world energy demand increases by an average rate of 1.6%/year, with fossil fuels accounting for 83% of the projected increase. By 2030, the world consumes 16.3 billion tonnes of oil equivalent (toe)/year5.5 billion toe more than it does todaywith more than two thirds of energy use coming from developing countries.
At an open house in Fisherville, concerning wind farms, a representative of the Ontario Federation of Agriculture said farmers can easily sell themselves short or even lose their property if they enter into bad agreements for the use of their land.
