  1.  @darknesswithin2136  Did you need to tell us that you are so clueless about the topic that you cannot contribute an argument?

  2. The cabon footprint is 1/100 of a coal power plant, 1/50 of a gas power plant and around 3/4 of a nuclear power plant.

  3.  @darknesswithin2136  One can look it up. If one is clueless and too lazy too look it up, one could think like you.

  4.  @yummygoy5138  Why should I supply public information and others do not need to? Just google carbon footprint windturbines...

  5. ​ @darknesswithin2136 I told you what to type into google. If you cannot do that, it is doubtful that you would understand the article in the first place...

  6. That does decide if something is green or not. One can get lung diseases or even suffocate to death from wood smoke.

  7. I hope you removed your windows, as glass windows kill a lot more birds than windturbines. And that not count all the bird deaths caused by global warming and cats. But it is nice how many people suddenly become bird protectors when talking about wind turbines...

  8.  @pedalingparson  You were the one being worried about the birds, which does not seem to affect you otherwise. That is called a double-standard. And there is no power plant that is biodegradable. To demand that from wind turbines is another double standard. Intermittency is dealt with using different souces of energy like solar, hydro, geothermal, biogas, biomass

  9.  @pedalingparson  Fossil power plants need to get dismantled too. Depending on size, it can take years. Some stand around for decades, because companies do not want to pay the dismantling. Btw. the landfills do not happen in every country. Germany banned the disposal of turbine blades in landfills back in 2005... I suggest to ask around, then you will learn how many birds die because of glass windows. Just because it does not happen to you does not mean that it does not exist.

  10. Easy solution. Tell the government to change the laws and make it illegal. Works in other countries too.

  11. Because fossil fuels lead to waste, pollution AND the relocation of our climate zones.

  12. One needs sand for cement.

  13.  @curtislowe4577  Assignment: learn about the process of cement making. "Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore."

  14. Wind turbines can be recycled to 80-90%. Recycled solar panels allow to build new solar wafers with 30% of the energy needed for unrecycled ones.
    1
  15. ​ @luckyx16 Because the enviromental laws of certain countries allow it. In other countries they are recycled. Complain about the laws, not the wind turbine. The framework of solar panels is trivial to recycle, no need to discuss it. Energy storage is needed when one has very much of solar and wind electricity production. No country is that far ahead, but there are multiple options. Pumped hydro, biogas, H2 storage, reddox flow batteries, lithium batteries.

  16.  @luckyx16  What I am ignoring? Concerning the batteries, which ones are you talking about? The organic redox flow batteries are easy to recycle and lithium ones are probably already used, otherwise they are too expensive, unless there are cheaper and better ones in 10 to 15 years.

  17. Aluminium is too soft. Considering how much energy they produce, their cabon footprint is negative.

  18. That is why it is not the plan to build only windturbines...

  19. Global warming does not make money. It costs, a lot.

  20. There are already multiple solutions.

  21.  @OddBall1958  They work quite well, but some nations do just not care about the enviroment and allow to dump the blades in landfills.

  22. Nuclear is expensive and not a good technology to cut corners. If done right, it can be an asset, but most countries cannot afford a lot of it.

  23.  @guy-tn2ud  What I wrote is fact. There are enough videos of smart people out there or better, read a study and do the research yourself.

  24.  @guy-tn2ud  I do not see what this has to do with my arguments. But please explain to me how it is a good idea to cut corners with nuclear power.

  25.  @guy-tn2ud  French nuclear plants had to be taken offline on large scale last year, because the service intervals were stretched too long. Many power plants are dependent on river cooling, without consideration for droughts. In Fukushima they did not consider large waves, despite the power plant being placed at the coast. In Chernobyl the technicians were not trained enough and the plant lacked sufficient security measures.

  26. ​​ @guy-tn2ud That is no fear mongering. That is what happened. There was a test done in the nuclear plant in Greifswald Germany, in 1989. Three of six cooling pumps were turned off. Suddently a fourth pump broke down the remaining 2 were not enough to cool the reactor. Control of the reactor was lost. The reactor was close to melting down before the remaining pumps got online. The accident was caused by "sticky" relay contacts. Shellenberger a pr manager, not a scientist or engineer. And yes, many scientist pointed out errors in his work.

  27. ​ @guy-tn2ud  this video tells the story of the usa, where proper enviromental protection laws are lacking. It does not look like this in other countries. Wind turbines are carbon negative, as they produce 10 to 50times more energy than is needed for their production. The dismantling takes up only a fraction of the energy needed for the production. Using fossil fuels leads to further co2 emissions and some countries do not have their own fossil fuels.

  28. ​ @guy-tn2ud  No, that tell me the enviromental laws of the countries. Germany has no energy shortage. It has a price problem, because it is dependent on fossil fuels and the main supplier does not supply anymore. Last year Germany was supplying Electricity to France, because they are dependent on old nuclear reactors, which were not serviced regularly. In other words, both countries suffer from being dependent on old tech.

  29.  @guy-tn2ud  Take a look at their gas storage. It is filled to 87% They get all the oil and coal they need. Electricity was not turned off.

  30. Fixed installations are powered by electricity, which can come from wind, hydro or solar.

  31. Wind turbines earn back the invested energy in 6 to 14 months, depending on model and location.

  33. It is not really burnt and especially not for electricity. The other compunds of the wings are burnt to make the fiberglass reusable.

  34.  @Diponty  The world is not make believe. Try some facts.

  35. There is no airborne pollution.

  36. Do you live in a desert? Under normal conditions they last 20 years or longer in the rest of the world.

  37. Aluminium is not strong enough for the big blades. Aluminium works in the low kW range.
    1
  38. That is not tough enough.

  39.  @spectrumofreality  Then look at the wingspan of planes and the length of 6MW turbine blades. One can use aircraft aluminium for smaller turbines, but these are less efficient.
    1
  40.  @spectrumofreality  Yes, you can build wings of many sizes. The longer they get, the thicker you have to build them, the heavier the wing becomes. Not a good thing for material that is spinning around quickly. Carbon-GFK composite material is much lighter and stronger than Aircraft Alumium.
    1
  41.  @spectrumofreality  The blades do not snap because they are made of composite material. The centrifugal forces are so great that a heavier material would ripp itself to pieces. Carbon composite material is used in aircraft construction, see Airbus A350 or Boeing 787. But I am sure Aircraft Aluminium would be better and they are just doing it for the fun of it...

  42.  @spectrumofreality  Large wind turbines pull around 20g at the bladetips. The blades are designed for 10^9 loadycycles.

  43.  @spectrumofreality  Weightless material? Interesting. That could work.
    1
  44.  @spectrumofreality  You claimed there is no weight at the blade tipps --> weigthless. I am still waiting for the wind turbines with steel or aluminium blades. The only bigger ones I found were build up to the 80s and were discontinued because realiability issues...
    1
  45.  @spectrumofreality  That is why I wrote that it is weightless material. That is great. With that one can build truly giant windturbines. Plesse share that knowledge with the windturbine producers. But that is not steel or aluminium...

  46.  @spectrumofreality  Feel free to continue to write about weightless material and ignore my question about windturbines with steel or aluminium blades.

  47.  @spectrumofreality  There was no need to tell everyone that you ran out of arguments. That was obvious.

  48.  @spectrumofreality  I never made that claim, but funny that you made another thing up.

  49.  @spectrumofreality  Nope, but nice try though...

  50.  @spectrumofreality  Not really, but your imagination is worrisome.
