How Viable Is Large Scale Wind Energy?
New submitter notscientific writes "Renewable sources of energy are obviously a hit but they have as yet failed to live up to the hype. A new study in Nature Climate Change shows however that there is more than enough power to be harnessed from the wind to sustain Earth's entire population... x200! To generate energy from the wind, we may however need to set up wind farms at altitudes of 200-20,000 metres. To be fair, the study is purely theoretical and does not look at the feasibility of such potential wind farms. Regardless, the paper does provide a major boost to backers of wind-generated energy. Science has confirmed that the sky's the limit."
Yea, I'll wait for more wind farms to actually be build.
I know folks that build those giant wind turbines. They think they build a good product (and they do), but not a single one thinks it'll be more than a supplemental. If for nothing else... Not In My Back Yard.
....No one has actually _built_ a wind power turbine setup that operates at well above the ground. I mean, consider the issues involved:
1. How are we going to keep those turbines up at altitude?
2. What are the costs of tethering these high-flying wind turbine installations?
3. Will these installations become hazards to migratory birds flying at high altitude, let alone passing airplanes of all sizes?
I'd rather build hundreds of nuclear reactors based on the safe liquid fluoride thorium reactor (LFTR) technology instead in the short to medium term, and in the longer term build space-based solar power arrays parked in geosynchronous or near-geosynchronous orvbit.
Every time a discussion about wind power comes up, some troll (usually with a very high UID, sometimes with an account created solely for the purpose) asks how putting up windmills will affect weather.
The answer should be fairly obvious. We have cut down a shitload of trees, which normally slow down wind. Putting up windmills? Slows down wind slightly, increases turbulence significantly, causing minimal localized temperature effects. Kind of like putting up trees. If there is any significant effect, it will be moderating, which is a good thing.
In addition, wind turbines don't actually cause any heating worth mentioning, unless perhaps they catch on fire. This is covered in the linked article, which had the GP actually cared about this issue, they would have found with google and read already. They cause thermal mixing, which can raise temperatures at a specific point, but which don't raise temperatures in a region. It only results in higher measured temperatures in a relatively small area downwind. This is expected due to (fractionally) lower wind speeds and greater thermal mixing.
In summary, anyone who expresses concerns about wind farms affecting weather is a shill, a troll, or an idiot, because these are not real concerns, and this is a well-known fact.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
You can get nuclear powerplant, a solar array, a coal burner, a gas burner, a wind farm. But something is going to have to generate that electricity you keep on consuming.
Make a choice. Oh wait, I forgot. Democracy, power without accountability. You can vote to have your cake and eat it to.

You may solo them, I prefer them in a group.
It's being done in the U.S. as well. Also known as pumped storage or pumped hydro.
People have studied it, and nothing significant happens because you don't stop the wind, just slow it down very slightly like all the trees you chopped down and terrain you flattened used to.
I really can't believe this got modded up even by one point. It is on about the same level as people who worry that Britain will be blown away by all the windmills, sailing off into the Atlantic.
