ladyfortuna: a commercial plane flying high overhead and you don't really notice it at first? Take that, make it ~20% louder, then make it go in a 1...2...3... rhythm. "Whoosh, whoosh, whoosh". All. Damn. Day. Long.

I hate that sound so much. Most days they aren't loud but when they are I have to have a fan on or something to drown out the noise. The jet that wouldn't leave.

So, no matter what type of energy we try to use, we're going to destroy the planet regardless.

we *could* get everyone to ride a bike to work, but no. that would fix too many problems. it's not the profit driven american way.


Have fun riding those 30 to 50 miles over hills.

Seriously, nothing we do seems to help. Hydroelectric? Cutting off water flow to other places, disrupting wildlife. Wind? Mass bird kills, heat buildup. Solar? We'd need a facility that covered the entire Southwestern US to provide any appreciable power. Nuclear? People are terrified of radiation, environmentalists won't let us dispose of the waste. Until we discover the magic of warp drives or cold fusion, we're boned.

prjindigo: Watts Up With That website

Willard Anthony Watts (Anthony Watts) is a blogger, weathercaster and non-scientist, paid AGW denier who runs the website wattsupwiththat.com. He does not have a university qualification and has no climate credentials other than being a radio weather announcer. His website is parodied and debunked at the website wottsupwiththat.com Watts is on the payroll of the Heartland Institute, which itself is funded by polluting industries

How about no.

edmo: Ah, the proverbial two edged sword.

The nutjobs who complain about wasteful green energy spending can now attack wind farms as harmful to the planet. The problem is they'll have to admit global warming is more than a theory - it's real. But since they know global warming is a crock, they know this study is more liberal bullshiat. But the wind farms will still be there.

I'm sure it sucks to be unable to compromise.


all the good names are gone: You obviously underestimate the cognitive dissonance of republicans. They will have no problem blaming wind farms and other green tech for global warming while vehemently opposing any data saying greenhouse gasses are to blame, or warming even exists for that matter.



Sorry but many environmentalist groups have long been wind power's most vocal opponents, from Oregon to California, to Colorado. And conservative Texas leads the nation in wind power production.

Put your bitter partisan hatred aside for just this once. Not only is it not productive, it is downright false.

Suppose a right wing nutbag comes into discussion about economic policy and goes on a rant about how "All democrats are Marxists who want to destroy capitalism, and hope for the destruction of the U.S. economy!!" Not only is it not true, but it makes right wingers in general sound silly. Yeah, well, guess what you sound like.

b2theory: What's strange is that the exact opposite thing should happen. When energy is removed from the air the net effect should be cooling. I want to say there were some large scale simulations done in the last couple years.

Someone failed high school physics...

You have energy in the form of momentum, which you are transferring from the wind to the turbine blades. This transfer is less than 100% efficient, so some some energy is lost as heat - heat that warms up the turbine blades and the air.

But that's a moot point, because that is not the effect the article is talking about. The article is about how the turbulence caused by the wind farms is mixing higher altitude warm air with lower altitude cool air at night, causing a net increase of local surface temperatures.


Keizer_Ghidorah: Seriously, nothing we do seems to help. Hydroelectric? Cutting off water flow to other places, disrupting wildlife. Wind? Mass bird kills, heat buildup. Solar? We'd need a facility that covered the entire Southwestern US to provide any appreciable power. Nuclear? People are terrified of radiation, environmentalists won't let us dispose of the waste.

Clearly the solution is to do nothing, then!

Hydroelectric's problem is all the good sites have already been tapped. There is some hope for pumped storage, though...

Wind does not cause "heat buildup" (protip: don't just read the headline off Fark) and the number of birds killed by wind turbines is dwarfed by the birds killed by buildings and cats. If you really care about birds, complain about those things.

The US peaks at some ~800 gigawatts of power consumption during the summer. At a conservative 8 watts/sq.ft. you'd need 100 billion square feet or 3600 square miles - just under 1/30th of Arizona - to meet that demand. Nobody seems willing to put out an estimate for total roof area in the US but I'm willing to bet it far exceeds that. There's no reason it all has to be in one place, after all.

Nuclear doesn't HAVE to have waste problems, from a technical aspect. The biggest factor of the problem is that profit motive gets in the way; nuke plants are expensive to build and maintain. All the problems with nuclear plants can be traced back to how plants that should have been decommissioned or overhauled decades ago are still going with original equipment.

We mustn't let the lack of a perfect solution paralyze us into inaction.

I'd hereby like to submit my idea to fellow farkers, that we can have a cushion in our car's seat that can absorb methane and transport it to storage in the vehicle for use as fuel. In states like Texas, this may eliminate the need for Oil, especially in the summer chilli cook off periods.

juhis: the change in temperature doesnt seem like much but it can kill off any earthworms near wind farms.

The change in temperature would be on the order of a fraction of a degree. At worst. The air temperature difference between the ground and a couple hundred feet up is most of the time going to be next to nothing, when it's not nothing.

Even if you weren't wrong we are constantly being reminded that the fraction of a degree that we are adding to global warming by burning petroleum is just enough to cause a feedback loop that will kill millions of Asians.

Somewhere back in my fark comments I said that Wind Farming would be found to have an effect on the climate. Im not a climatologist, I just figured you can only suck so much energy out of something before you begin to have an effect on it. I think I questioned the effect that increasing the surface drag on the jet stream would have.

I was of course not correct, but it turns out that you cant just take free energy from things, it all has an effect somewhere. And even if the effect is microscopic, so is our impact on global warming.

They can get very warm because of their dark color so a large area or field of them can warm up the air.

Jesus cocksmoking Christ, this isn't thermodynamics, it's DYNAMICS.

At night there is a net loss of heat from the surface of the earth (because the sun is down, durr) as the surface emits IR upwards. This causes a nocturnal inversion. This effect is strongest when there are clear skies and no wind at all (so it's not as if there will no longer be modified warmer nights at the surface with wind farms as the blades don't turn when there are no winds).

All the blades do is mechanically mix the air - causing air near the surface to rise, and air aloft to sink. This causes the nocturnal inversion to "mix out" - the same thing that happens naturally after the sun rises in the morning - except the sun does it from forcing mechanical convection due to surface heating.

This effect has been known for a few years now. Note that there is NO NET WARMING - it's a redistribution of temperatures, not local heating. So morons blathering about energy being created can STFU, you don't know WTF you're talking about (the tiny, tiny amount of heat created due to friction with the blades and the assembly itself is negligible).

So, to review: No net heating, just a "homogenization" of near-surface air, which erodes the nocturnal inversion. Makes it warmer at the surface, cooler aloft (and "aloft" is only maybe the bottom few hundred meters of the atmosphere).

Now that doesn't mean we should just ignore this effect. This effect may indeed have non-negligible consequences to agriculture and plant and even animal life. This is what needs to be studied more.

The entire system would be cooler, but the local system could certainly heat up. Effectively the wind farm is acting as a Dam for the heat convection current. Heat is building up on one side of the Dam just as water would.

They do the same thing with the citrus crops in Florida when a cold air mass moves in that is below freezing. That, and spray water on them (latent heat of fusion) and burn shiat.

Bad analogy. The blades are forcing vertical advection, not stifling convection (the stability of a stratified layer inhibits convection). There is no "heat buildup".

Probably - but a 1 degree F increase over a large area - especially when superimposed on the GW trend - is a significant climate perturbation. The jury is definitely still out on whether this is something that will have detrimental effects.
 
2012-04-30 08:25:23 AM
So a smaller local system has no impact on the larger scale?

So a melting mountain glacier has no impact on anything else because it's local? Or the salinity of this small tract of ocean has no effect on the salinity of the rest of the sea, because it's local?

Oh wait, you guys really aren't scientists.

Yes, in fact, for the next 100 years or so as the thermal inertia of the system continues to adjust to the increased CO2. See the IPCC Summary for Policymakers, towards the end where they have the model simulations. Look for the simulation where we completely stop burning fossil fuels.

The big problem with geothermal is that the majority of the heat generated in the earth's core is due to radioactive decay. Thus, it's really just nuclear power repackaged in a "green" format.

RUN AWAY- YOU'RE GOING TO DIE!!!!!! IT WILL BE WORSE THAN NAGASAKI, CHERNOBYL, 3 MILE ISLAND AND FUKUSHIMA COMBINED!

/Bummed that I didn't buy my house early enough in the build process to get a geothermal heat pump installed. It was a ~$20k option from the builder, but you needed to do it before the foundation was finished.

There isn't an IPCC model simulation for a zero emission scenario. The closest is a stabilised concentrations scenario. This entails producing just the right amount of emissions to maintain a constant concentration as various carbon sinks scrub a fraction from the atmosphere each year.

There's a brief description of a zero emissions simulation here. Essentially GHG concentrations begin reducing immediately, reducing the forcing and offsetting expected warming due to thermal inertia, producing zero net temperature change over the next few hundred years.

'reducing the forcing' would be better stated as 'producing a negative forcing'.
