Wind turbine backlash article

We read and looked into solar and decided anything out there wasn't cost effictive. So we just made our home tighter, and more energy efficient. We upgraded the AC and now our gas furnace is going on 16 years old I'm going to price one of the new ones that are 95% efficient. There are a lot of ways to cut utility usage through conventional means, and at this time are much less expensive. I don't see alternatives as being affordable and having a decent payback time yet.

My electric usages the last 4 months are 709,801,832, and 630 kwh's, they, in the past had been as high as 2500 kwh's per month in the summer. Now we likely won't have AC on till June or July with the Tech Shield and I lower the furnace temp to 69 at night and use an electric blanket in the winter, that made a huge difference in amount of propane used. The first bill is December and I have 300 foot of Christmas lights down my fence that I leave lit 24/7. In the past the bill was over $200, a couple years back I changed to all LED bulbs and it hardly adds anything to the bill, amazing.
We went from usage over 8 years ago of 22,500 kwh's a year to around 10,000+. This was due to adding insulation, Tech Shield roof decking, and new appliances over a period of several years. New exterior doors and frames, the steel core doors. Front load W/D showed a dramatic change, over 40% less water, detergent, and way less electric. A large double door fridge that is HE, along with the dishwasher. My stove, water heater, and furnace are gas. Have reduced those usages also, last year just 3 tanks. We have a 2000 sq ft house, lots of windows with dual pane, low E glass, 5 TV's, yeah, I know, 2 to 3 computers on most of the time. I also sealed all openings, not weep holes of course, with caulk and our 35 year old house is pretty tight. Of the TV's 3 are the flat screen wall mounted, they use little. 1 is a small one in my sewing and ironing room, the other is an older flat screen larger TV in the living room. I went to all the lower use light bulbs in everything. The last upgrade we can do is the furnace. We are adding DD her own bathroom and she will have a small electric water heater for that so I expect that to raise our bill, also that room, and my new closet will add some sq footage to heat and cool, so I expect some increase. And of course hubby says our water well pump uses quite a bit. But doing these things made more sense to us and we have seen dramatic decreases in our bills even with rising prices.

Now, the Todds have eight 1.5-megawatt turbines near them with the closest just 2,400 feet from their home. :

I have a kid that drives past my house daily that likes heavy bass on his sound system. Can hear and feel the bass long before his car comes by. In the sonar shack on the sub I was on you could listen to the thump of ships propellors miles away. I understand the power of low frequency sound waves, doppler, etc. I just can't see how it could cause a bat's lungs to "burst". MikeD74T

The best use of solar appears to be solar thermal. I wonder how much energy could be saved nationwide if all new houses had a solar thermal panel for domestic hot water? Retrofitting is a pain. When I lived in Vegas all the new houses came with a 'loop' in the garage for a water softener. Even just providing such a loop in the attic for a solar thermal panel would probably go a great ways towards homeowners deploying the technology.

I agree, but not just a solar panel, but several panels and a large storage tank. One of the largest users of energy is that litle comfort we have grown accustomed to called on demand heat... Either in the generation of this heat, or the waste of it thru leaky, poorly insulated houses and hot water systems. The first step is in using less by insulation. There are a lot of wasted rooftops in this country. Solar collectors and super insulated storage tanks are proven viable technology. That suprinsulated storage tank acts as a thermal battery and keeps the hot water tank hot and the electric element or burner from drawing power or fuel. A large enough collector and storage system heats retrofitted floor radiant heat which keeps the house warm untill the heat in the tank is exhausted. But those hours of heat are that many more hours that your furnace or heaters are not sucking down killowatts or gas or fuel oil... Here is an interesting article.

Solar collectors need not be particularly expensive. They need to be cheap enough that you can cover a roof with them. Comparing Solar Collector Performance -- Small Panel Tests

The same applies for cooling. Insulate insulate insulate. Shade the southern exposures and windows so the house dosn't collect unwanted solar energy. Ironically, a roof covered with solar panels actually shades the roof and lowers attic temperatures. The more you can separate the inside environment from the outside environment, the less energy it requies to control the temperature of the inside environment. Less is more.

As for the bat lung collapse, well this can happen to humans in close proximity to an explosion/rapid pressure change. I suppose it could happen to a bat flying in close proximity to the pressure difference created around a large fast moving airfoil. I would think this to be a very small region around the airfoil, and would think it far more likley that they would be struck by the blade. Perhaps their senses are keen enough, and their reflexes fast enough, that they can sense the blade approach, and just miss getting struck only to pass thru the low pressure region of the airfoil and rupture their lungs. I didn't read the article, but I am guessing that they started finding dead bats with no visible signs of trauma from a blade strike, and lung damage was found to be the cause of death?

Google'd bat death by windmill and found numerous articles quoting the findings of one scientist in Alberta. His theory is bats fly into the low pressure area behind the blade causing the expansion of the air in their lungs. May be something to it after all. Windmills world wide are killing bats but so far no one else appears committed to exploding lungs, but someone has to be the first to be right & it could he him. Similar to the caison workers killed during the construction of the Brooklyn Bridge only much faster. MikeD74T

I did read that and I would not want to have to be in the Todds situation either.

Well it looks like im going to be the odd man out here for my support of wind energy, but here goes:cool:

First let me say that I was unaware of the increased risks to bats caused by wind turbines. That was a surprise.

That said, how many bats are killed by other means besides wind turbines? I know that when i was growing up, i found several bats that had ran into the windows of our house (it had a completely glassed in front). Personally i think that the gains to society from clean power (I KNOW dirty power, we live downwind of a coal fired station, and have an open pit coal mine in our town) far outweigh the deaths of a few bats or birds. Its unfortunate about their deaths, but the technology to prevent it will come soon.

Also, the descriptions of the noise of the turbines have been exaggerated in my opinion. I would not describe it as the thump from a car stereo ( I used to be involved in that), and the noise from a turbine doesnt travel like the bass from one. The noise is more of a whoosh than a thump. There were no vibrations in my chest nor could i feel it in my feet any time ive been around a turbine, in varying weather conditions. If you actually had your hand on the tower, you could feel a vibration, but that vibration does not travel.

Ive been under most of the large turbines in my part of the province and in PEI as well. These are large installs. As a matter of fact i was under one today. The noise of a couple carpenters hammering a kilometer away was louder than that turbine!!!

I have to question the sincerity of the videos online that try to push the noise issues. In several ones ive watched the sound levels have been pushed way up to exaggerate the "noise". You can tell this from the volume of the road noise of a passing cars. Most of these videos have been posted by people with an anti-wind agenda.

In the end, wind, PV,hydro , nuclear and increasing individual power savings are the ideal mix. IMHO burning coal and oil belongs with the industrial revolution. Our community has had many deaths in the production of coal. Time to move forward and adopt new technologies for energy production and savings.

The same applies for cooling. Insulate insulate insulate.

I've kept up on the solar heating threads on here, would love to do something like that but it can't go on the house because there is no way to get the plumbing from the roof to the 1st floor, centrally located, room where my hot water heater is. That is without going on the outside of the house which would likely ruin the looks of my house and hence my comment on having some simple pre-plumbing done at construction time. Since the hot water heater is in a closet there is no room for an extra tank either... unless it can go under the house in the crawl space.(???)

Now as for cooling/insulating. We rarely run the AC in the summer. Part of this is that we moved here from Vegas and it really doesn't seem like its that hot here ;) The other part is the way this house was built. The house is on footing walls with about a 3.5 to 4 foot crawl space. The footing walls are insulated and vented, the floor is not insulated.... or sealed very well around pipes,wires etc. This 'leaky' floor makes the house colder in the winter but I think it also keeps it cooler in the summer. I will probably go around seal everything tight and insulate the floor, at least the northern/coldest side. (Tired of listening to the wife all winter). I've been watching the solar thermal threads to see about adding radiant for this part of the house. I anticipate I will be running the AC more after insulating the floor as the house will no longer 'draw' cool air from the crawlspace.

I just read the backlash article. I can understand the residentail frustrations since the windmills were too close to the homes. There is a windmill less then 5 miles from here that is huge, but its right next to the highway on route 104. The windmill seems to be well placed, away from the homes, and in a industrail area. Its a nice thing to see when I am driving to the store or work that its working to save the environment. I am truly sadden that the other windmill farms is placed in a wrong location near people homes.

I don't think I have ever been in a crawlspace that I would WANT to draw air from... As for a solar storage retrofit, the storage tank does not have to necessarilly be inside the house. In fact, due to the weight, under the house or in a shed outside the house is probablly better. A pluming passage to the roof can be difficult, but I can think of several ways to make it happen, and still look decent, at least not as noticable as that array of solar panels on the roof. Free energy collection does have it's price I guess:) You are most definitely correct, that it is way easier to set up in new construction though.
