NextEra Energy uses over 800 metric tons of concrete per wind turbine

Ontario’s concrete industry has been enjoying the benefits of the province’s efforts to construct more wind energy and turbines. Concrete has been the material of choice to use as the foundation for wind towers, according the NextEra Energy, one of the largest wind and solar energy developers in North America.

“Given its durability, resilience and continuously improving environmental footprint, concrete can play an important role in building sustainable infrastructure,” said the Cement Association of Canada in a statement to the Daily Commercial News. “Enabling the deployment of sustainable energy by providing an important building material for wind turbines is one exciting example. Concrete also provides added economic benefits to communities where these turbines are built since concrete is always produced locally.”

NextEra Energy uses over 800 metric tons of concrete for each turbine they construct, with investments worth $1.7 billion and 8 wind projects in Ontario, also adding more jobs in the concrete industry. Read article

  1. It should be pointed out that cement is the number 1 carbon contributor in the world. The production of 1 pound of cement also produces 1 pound of C02. In 2011 enough cement was used, for turbine bases, to pave a 4 foot wide sidewalk from Los Angles to beyond Sydney Australia. Vestas, according to it’s own website used 32million metric tons in a year when it only had 11% of the market. Now add to that all of the cooling oils used in each turbine, all of the emisssions from all of the trucks, planes, trains, ships, bulldozers, cranes, and other equipment used just to move and install these things,,,, not very carbon friendly. All of this carbon does not include getting and movement of the raw materials. In the same year Vestas used 32million tons of cement they also used 700,000 tons of steel. And finally, what about the non recyclable blades? Big wind is a big lie that is only about big money and greed.

  2. I should have mentioned that the 32 million tons of cement used by Vestas would have taken 160,000 cement trucks carrying an average of 10 yards of cement weighing approximately 40,000 pounds each, and we all know how “green” cement trucks are!

      • Vestas puts out an employee publication called “The Grid.” You can find it at their website under media. Here is a direct link: http://www.vestas.com/en/media/the-grid.aspx They no longer have the issue posted where they brag about the amount of cement used but I do have a hard copy. It is alos interesting that they have no issues posted for 2012. If you check out the October 2010 issue you will see that my numbers on the amount of steel used was wrong,, (they say memory is the first to go when you get older!) Total amount of steel used by Vestas and it’s sub-suppliers was 900,000 tons, enough to build 27 Eiffel Towers. When you go the grid by sure to look at the section in it titled “By the Numbers.”
        Here is my math on the amount of cement: From the American Cement Industry I found that cement trucks carry between 8-12 yards, so I used 10 right in the middle. 1 yard = 4,000 pounds; 10 yards=40,000 pounds. Vestas said it used 160,000 loads. 160,000 X 40,000= 64,000,000,000 pounds.64billion divided by 2,000= 32 million tons.

  3. Well, duh, of course the Cement Association of Canada is singing the praises of the IWT industry. It is not like they are neutral on this topic.

  4. Just think !!! Somewhere in the next post-historic ‘age’, some caveman -like creature will be digging in the earth here in Ontario and elsewhere, by events that laid the land to a barren waste, only to discover a hard substance in the ground, and wondering what the heck it is !!!Wow !! I believe it’s a prehistoric substance of eons ago, called concrete !!.Those blocks of cement will be a constant eternal reminder of just how badly this so called “government’ looked after its own people…NOT !!..

  5. And this is why so many companies are trying to open aggregate pits in Ontario, creating more civil unrest.

  6. This is a situation where lie upon lie has been piled and it makes it very difficult to combat all of these lies at the same time.

  7. As a point of interest, 800 metric tons translates into 1,763,698.1 POUNDS !!Al little over 1 3/4 MILLION POUNDS, PER TURBINE !!!Multiply that by the number of turbines now, and on the drawing board, and it boggles the mind !! I can see why the concrete suppliers are licking their lips as well, all the way to the bank ! ..Not to mention all the steel reinforcing that goes into those blocks!!!

  8. Makes perfect sense………….pave over valuable farm land………….eliminate local food supply…………force farms to fold up………..eliminate rural living in favour of urban box living and Voila!….Agenda 21 is complete!
    This Government should be charged with TREASON!

  9. How rich is this?

    Toronto “Elites”, who love, but don’t want to live next to IWTs, and all the concrete that goes with them, were the major force that rightly defeated the proposed Melancthon Mega Quarry.

    Ever the bandwagon jumpers, the Elites found a trendy cause to align themselves with Guru Suzuki and other “green” hangers-on. How quaint it was, all those cute “stop the Mega Quarry” signs perched on the lawns of these hypocrites. But seriously, wasn’t it the mother of all feel-good moments?

    Now, the Elites can get back to doing what they do best: not giving a rat’s patootie about the state of affairs north of the 407.

  10. And NexTerror is proud of this????
    Cement – From Wikipedia, the free encyclopedia:
    Cement manufacture causes environmental impacts at all stages of the process. These include emissions of airborne pollution in the form of dust, gases, noise and vibration when operating machinery and during blasting in quarries, and damage to countryside from quarrying.
    The cement industry produces about 5% of global man-made CO2 emissions, of which 50% is from the chemical process, and 40% from burning fuel.[51] The amount of CO2 emitted by the cement industry is nearly 900 kg of CO2 for every 1000 kg of cement produced. [52]

  11. Mixing the concrete is local but one time only jobs for each project. Bring in lots of cement and extra trucks and the diesel fuel to do the job as there aren’t enough local trucks. How does this help the local cement business owner? Unless local trucks go to other job sites as needed?
    The cement producers make out but the local cement business dosen’t make out except for a limited time during construction.

    This is all voodoo economics!
