Coal is Not Being Replaced By Wind

by Scott Luft, Cold Air

Wind is not going to replace coal in Ontario. There are many claims wind generation is yet to replace any fossil fuel generating station in any jurisdiction, but Ontario may be particularly poorly suited for the introduction of industrial wind generation into our supply mix. Electricity pricing looks to be an important issue destined to occupy much of the discourse in Ontario’s election this fall.   Read article here

  1. Another issues seems to be that magnetic fields from power lines actually increases the risk of children developing asthma if they are exposed during fetal development.

    But Dalton said that dirty coal plants are what caused all those respiratory issues, isn’t that why we are criss crossing the entire rural landscape with clean wind factories?

  2. Power transformers have close links to leukemia…especially in developing children..but Liberals know all this

  3. Just when the power is needed the most all of the factors in Ontario are working against wind energy, or lack of energy in the summer.

    There is about 1/3 the amount of wind speed/energy available in the summer.
    Also warm summer air is about 15% less dense than cold winter air, which means an additional 15% handicap in the summer.

    Output of any industrial wind turbine is determined by the following equation

    Power = 0.5 x Swept Area x Air Density x Velocity x Velocity x Velocity (air speed – velocity cubed)

    Search ‘power curve wind turbine’ for the practical application of this.

    Wind speed in Windsor Ont, all of Ont is about the same.

    Winter about 13 miles per hour avg.
    Summer about 9 miles per hour avg.

    Remember these wind speed numbers have to be cubed.

    Winter 13 x13 x13 = 2197
    Summer 9 x 9 x 9 = 729

    Air desity Winter –10C = 1.3229 kg/cubic meter
    Air desity Summer 30C = 1.1354 kg/cubic meter
    (these density numbers are for dry air, increased humidity makes it a larger difference, someone else can do those calculations)

    • So David, if you take (Summer avg. wind speed – cubed) divided by (Winter avg. wind speed – cubed) x (Summer density) divided by (Winter density) you get 28.5%, which means you get 71.5% less power in the summer than in the winter on average from IWT’s, in addition to all of the other inefficiencies and drawbacks we know about !

  4. Thanks BOB. Putting it in different ways is good for more people to have a look and understand another bad problem with this.

    The little chart with the news story shows the real life numbers. The red line shows almost 500,00MWh wind produced last winter. This summer it looks like the number is around 150,00MWh. There it is in actual numbers, about 1/3 for summer. Every summer will be the same.

    More obsurdities

    All of this comes from mathematics and science that was known and proven before 1920. Yes, almost 100 years ago the realities of wind energy were known.

    Ontario now has about 1000 industrial wind turbines. In order for Ont to reliably produce a significant amount of electricty from wind in the summer, say just 30% of Ontario demand. The amount of industrial wind turbines would have to be increased by about 50 to 100 times. That is 100,000 turbines for Ont. And it still would not be gauranteed 100% of the time. And occasionally 90% of the turbines or more would have have to be shut down because of too much power. The cost: Trillions of dollars, a number similar to the US government debt load.
