Open letter to Mr. Hopkins:
Allow me to respond to the points you made recently regarding wind turbines.
1. Wind will never run out. (oil will)>
Yes, we'll run out of oil. But that is irrelevant in any discussion regarding the generation of electricity. Just the mention of it shows you've put little effort into understanding the topic. Our oil consumption is largely in transportation.
In America very little electricity is generated by burning oil. I think the figure amounts to about 3%. Most of the oil used is poor quality and of no use for anything else. If you wish to help reduce our dependency upon oil start planning your shopping wisely to minimize time on the road. Buy a fuel efficient auto or a motorcycle.
Avoid the mythical savings with ethanol fuel blends. They're a farce dwarfed only be the size of wind turbines. Corn is perhaps the worst possible choice for ethanol production. In the growing and transporting of the corn fuel is expended. The alcohol manufacturing process is fuel consuming. Diverting it from food to fuel drives up the price of food. Using it in cars not intended to burn it will damage engine seals. It has less energy per gallon than gasoline. Your fuel mileage will suffer.

Consider walking or bicycling too.
What you should mention running out are the fossil fuels that are actually used in the majority of our generating facilities. Particularly coal and gas.
They'll run out and we'll find that our ever increasing hunger for electricity will only be met by using nuclear power.
What little power we can hope to squeeze from the wind will be dwarfed by our increase in consumption.
Eventually nuclear will be our only hope. Why not admit this now and not blot our landscape with thousands upon thousands of wind turbines that won't really contribute to any solution?
I DO walk and ride bike. I also USE fluorescent lights in as many fixtures as possible. The main problem with ethanol is that we are using the WRONG type of crop to produce it. What about the miles and miles of abandoned farmland here in New York and other depressed East Coast states? Shouldn't we be using them for ethanol production, our economy would probably pick up then.
2. Change is good. We all need change in our lives at some point, it can be hard to deal with but it has to happen some time.>
Yes, change is good. Turn off the lights when you leave the room for a change. Insist that your place of employment not run all the office lights while the place is closed for a change. Consider fluorescent lighting as a substitute for incandescent lighting for a change. Be mindful of the mercury in those fluorescent lights though. We need to work on recycling that for a change.
Yes. I do use them.
Insist that elected officials not jet around the country when teleconferences would suffice. How many tons of carbon do you think the current crop of presidential hopefuls have dumped into the atmosphere? This is at high altitudes where it has more impact than surface dumping. Read up on that along with the rest of this stuff that you clearly don't understand.
Buy a smaller car. Oooops, I already mentioned that.
That is my prerogative. Good idea though.
3. Future generations will thank us for thinking of them when they see the investment in a basically infinite supply of power. Yes maintenance could possibly cost in the future, but what is that cost compared to being with out electricity in the near future?>
You left off intermittent from your description. That is the largest flaw associated with wind. Not noise, not property value loss, not view shed loss, not the killing of birds and bats, none of that. Although I don't want to discredit those components as they are all very important.
The intermittency of wind is its biggest failing. It must have back up power supply. Otherwise the power fluctuations will create problems for the grid. If that back up is nuclear or hydro then why not just use them all the time? If that back up is fossil fuel generated power IT CANNOT SIMPLY BE TURNED OFF. THIS IS A POINT THAT YOU AND YOUR ILK REFUSE TO SEE OR UNDERSTAND. IF YOU CANNOT TURN THE COAL FIRED PLANTS OFF THEY ARE STILL BELCHING OUT POLLUTION. THE TURBINES SPIN AND PRODUCE ELECTRICITY WHILE THE FOSSIL FUEL FIRED PLANTS BURN FUEL TO SUPER HEAT WATER TO SPIN MASSIVE STEAM TURBINES THAT DRIVE MASSIVE GENERATORS. THIS ENTIRE PROCESS HAS TO BE UP AND RUNNING BEFORE THE WIND DIES AND THE TURBINES STOP TURNING. WHEN DO THE TURBINES STOP TURNING? WHEN THE WIND STOPS BLOWING ADEQUATELY TO TURN THEM. WHEN DOES THE WIND STOP BLOWING? WHEN IT BLOODY WELL FEELS LIKE IT. SO THE FOSSIL FUEL FIRED PLANT YOU ARE TRYING TO TURN OFF IS STILL SPINNING AWAY.
Maybe you should read the points I've posted on the CWW forum about this. I've already acknowledged that wind isn't the most reliable and put forth a solution.
If this concept is still above your head go out and purchase a portable generator driven by a gasoline engine. Fire it up but don't plug anythng in. There you have it, a mini-fossil fuel plant sitting there burning fuel but not actively supplying electricity to anything.
ALL OF THIS RAMPING UP AND DOWN OF FOSSIL FUEL FIRED PLANTS REDUCES EFFICIENCY. Think of going from point A to point B in your car. If you hold steady at 60 mph you will consume less fuel than you will if you average 60 mph by constantly accelerating and declerating from 50 to 70 and back to 50 mph.
I know this. Maybe you should be sending emails to the power company executives, instead of wasting energy writing to someone who has no power in this respect.
4. Have you ever traveled to California? They have wind farms there that stretch as far as the eye can see, it's not ugly it's very beautiful. If you don't like looking at them then don't. >
Okay, you like them. Have a small one erected on your property. Use it to supplement your electricity. You can even set up a bank of batteries to store electricity in while you're not using it if you'd rather do that than sell it to the utility in your area. Bear in mind the battery pack to store electricity for a conventional wind plant would be quite massive and impractical before you even think about that as a solution to intermittency.
Good idea, they can be supplemented with solar panels and kinetic energy.
Don't be so bold as to insist that I have to let some greedy developer build them uncomfortably close to my home where I'll be subjected to an endless reminder of the pitiful waste of space, time, and effort that they really are. I used to think they were a good idea. Then I took the time to learn about reality. I don't like them. I went to the ones in Tucker County West Virginia. They're imposing noisy structures.
5. Birds are smarter than to get close to a large fan like blade moving rather slowly at the slowest of wind speeds and sorta fast at higher speeds, but they aren't invisible.>
You really don't understand these things at all do you? Blade tips reach speeds approaching 200 mph. From a distance they look slow. If you know how to, calculate the blade tip speed of a 120 foot long blade turning at 20 rpm.
Birds haven't evolved with wind turbines so they aren't "smart" enough to avoid them. In fact many die from strikes. In particular migratory birds and birds of prey. Look up Altamont while you're enjoying California turbines. They've slaughtered a lot of birds of prey.

NO REALLY, these are stupid birds if they CAN'T see a 120 ft blade.
Then there are bats. Don't be fooled by wind shill bat experts telling you they are no threat to feeding bats. They aren't a threat to feeding bats. Feeding bats fly well below the turbine blades. They use sonar to navigate while feeding. Unfortunately when they migrate they don't use sonar and they fly well into blade heights. And they die. By the thousands. Look into bat kills at Mountaineer.

Bats aren't at all like birds in their reproductive behavior. It takes them much longer to recover from dents made in their population. The effects of one wind generation facility will make a notable dent. The combined effects of thousands of turbines placed in groupings in the mountains of the eastern US will wipe species from the face of the earth. Think of the resulting blooms in insect populations and the zoonotic diseases they carry. Zoonotic diseases are those that affect humans as well as animals.

Ok, set up bat repellent ultra-sonic devices near them. Hmmmmmmm???
6. Remember that wind is what is moving the blades of a windmill, they aren't self-propelled.>
Why you felt a need to make this point is beyond me. Stunning. I'll respond anyway.
Remember that wind doesn't blow with any predictability. If it is too fast the blades have to be locked down to avoid damage. If it is too slow the blades won't turn unless electricity is run through the generator to keep them turning. A generator and an electric motor are one and the same design. Spin it by some outside means and get electricity. Run electricity to it and it spins. They really do run current through them to keep them moving as this allows them to function at lower wind speeds due to the fact it takes higher wind speeds to get them started. That electricity has to come from somewhere. Where do you think it comes from?
I know how generators work. I know how wind turbines work too. So you are telling me that these things are HUGE fans?
7. Windmill technology has been around for centuries.>
Yes, it has and it has been stagnant. Only recently has it been used to attempt to generate electricity on a large scale. This has caused problems in Europe. It has provided no benefit in terms of reducing carbon emissions anywhere. I have yet to see any evidence that it has. It can't for reasons I stated above.
Power grids are complex and massive machines. Wind generating facilities place a strain upon them that results in the need for thousands of miles of new transmission lines just to allow for all the shunting of loads back and forth. More damage to the environment. Those transmission lines don't just sprout out of the ground.
They are used to pump water. And still used in many places.
Please stop and take a moment to think about these points. I'd rather like to think that you will be an activist in areas of environmental concern that are more useful in the future, such as agricultural run-off into streams, and factories blatantly dumping toxic waste.
Thank you for your time, Sam Hopkins
We ARE actively focusing on facilities that can and do adversely affect the environment. The construction process alone has the potential to destroy springs and cave systems. The siting of them fragments forests. Run off is generated that threatens to flood areas. One wind plant may be insignificant. But any quantity of them to actually contribute to our power demand will have cumulative effects that need to be looked into prior to proceeding ahead full steam.
I really think you need to read my replies on the CWW forums. Erosion can be prevented by simply planting grass. Leachate can be treated. There are regulations for this.
Please stop and take the time to actually learn about the subject before you form an opinion.
Thank you for your time,
Jimmy Tragle D.V.M.
