  1.  @Momoka7  Then they are missing a core information of the process. Feel free to look it up. And no, it is not standard cement, but the minerals in the glass are similar to the minerals in the cement, so it works quite well.

  2. Boats, cars, buildings. They are used for many things. And no, recycling them does not produce more CO2 than a coal power plant, unless you are talking about a model.

  3.  @terenceiutzi4003  They are produced that way.

  4. ​ @terenceiutzi4003 They make the stuff I wrote.

  5.  @terenceiutzi4003  They use long ones.

  6.  @terenceiutzi4003  One can repair the blades. In countries were the turbines run longer than 20 years, it is done regularly.

  7.  @terenceiutzi4003  The US favours short lifetimes on the turbines. No need to run them long, when you earn all the money in ten years.

  8.  @terenceiutzi4003  They run much longer in other countries, at a fraction of the cost. Do you have a source for 5$/kWh cost of electricity? You are missing information. Btw. Tvindkraft runs for over 45 years.

  9.  @terenceiutzi4003  They last more than 20 years in other countries. Siemens offers turbines with a 35 year certification and GE offers them with a 40 year certification.

  10.  @terenceiutzi4003  Humidity is no issue. There are many offshore farms without that problem. Which farm is supposed to have these problems?

  11. ​ @terenceiutzi4003 I do.That is why I question your information. Looks like you have no source and just made it up.

  12. They spin with over 200 km/h and are exposed to the elements 24/365. Rain, ice and dust have an effect like sandblaster after all this time and the leading edges of the blades get damaged, which reduces their aerodynamic efficiency by a lot. Companies are working on multiple solutions. The easiest, but most costly one is regular maintenance. Small damaged areas can be fixed in the field, before there is a need for replacement. Well maintained blades can last over 25 years.

  13. People throw away working stuff for many reasons. Usually when new stuff is better. Wind turbines are usually designed for 25 years. Some manufacturers aim for 30 years for the mid power range (6 to 8 MW).

  14.  @dafunkmonster  That can happen, but is obviously not normal.

  15. Windturbines leave less waste.
    1
  16. They are not the only company doing this. And windpower is not really harmful to the planet compared to the alternatives.

  17. There is no technology to do anything cleanly. There are only technologies that use less ressources than others.
    1
  18. How long do you plan to wait for nuclear power?
    1
  19. There is no need for that. Make it mandatory to recycle the windturbine, as some countries have done. That is what laws are for. Do not allow people to throw their rubbish into the wilderness.

  20.  @ThisIsToolman  That can be regulated too. Owners have to build up reserves for that purpose.
    1
  21. ​ @ThisIsToolman The reserves can be regulated too.
    1
  22.  @ThisIsToolman  The reserves should not be something that needs managing. One can use banking guarantees or a security account, which result in monthly costs and cover the dismantling of the whole turbine.

  23. That seems to be an US problem. With proper care the blades last 20 years in other countries. And the blades do not get buried there either. Why we should do this? To prevent climate change. Unless one does not mind to invite the climate refugees into ones home, one can can continue to burn fossil fuels.

  24. Problem is that we do not do nothing. We all consume stuff. Using wind turbines to produce electricity reduces the damage. It does not stop it.
    1
  25. If waste can be burned, it should be burned. Just burying all that energy and take up space is a waste. Landfills should be reserved for waste that cannot be burned.

  26. The energy is much less than these turbines produce.
    1
  27. Which is only a fraction of the energy they produce.
    1
  28. But they do. Depending on location and power, they generate 10 to 50times as much energy as is needed for their production.
    1
  29. Not really. How are windturbines supposed to solve health care?
    1
  30. Nuclear is too expensive and too slow to build.
    1
  31. China builds more renewable energy capacity than the US and Europe together...
    1
  32. With service they last 20+ years. Only neglected blades fall into disrepair that quickly.
    1
  33. It reduces the CO2 output by a lot.
    1
  34.  @michaelbaja1854  The production and disposal is added.

  35. A good setup vaccuums the dust. The way shown in the video is not the right way. At least the workers should wear facemasks.
    1
  36. It is more efficient to recycle the blades in ones own country.
    1
  37. The capacity factor is determined by the wind, not their construction.
    1
  38. Why should there not be profit?
    1
  39. Some companies are paying money for the right to build wind farms. Seems to pay off.

  40. Other materials do not have the strength/weight ratio, which makes the big turbines possible. If power in the kw range is enough, there are turbines with aluminium or steel blades. Small ones can be even made from wood.

  41. Physics say it does.

  42. ​ @larrya7822 I prefer scientist that do not ignore physics.

  43. They produce a lot less CO2.
    1
  44. You need also water. Too much water makes you drown. CO2 works similarly. Without it, we would live in an ice age, with too much, many people would live in a desert. Imagine 8 billion people migrating to the few habitable places remaining.

  45. Only in countries where recycling is not mandatory.

  46. Physical stress and blade erosion. One has to remember that the blades are under physical stress, even when they are not running. Storms, shifting winds and turbulence affect the blades. The tips of the bigger blades have to endure around 20g of centrifugal force, while the blades endure load changes around a billion times in 20 years. More modern designs have a lifespan of 25 years and a few companies offer 30 years lifetime.

  47. People have a different view on the cleanliness of nuclear waste.
    1
  48. That does not destroy the planet. The planet will be here, long after we are gone.
