This is a historic event that makes me very happy. Where this will lead us? Any ideas? I feel this is the beginning of the dam breaking and the waters starting to flow. According to cleantechies.com (linked below) It will provide power for over 400,000 homes. Also the article includes quotes from Salazar stating "This will be the first of many projects up and down the Atlantic coast." Very good complimentary information there too.

This is hyperbole based on using the peak rating of the turbines rather than the mean energy produced when averaged over all wind conditions.

Off shore wind for our country,
Generating power, a new industry,
This century will need, power to feed,
Grid lines for houses and factories,

We have coal for sure, energy not pure,
Giving off pollutants and taking miners lives,
Atlantic oil leaks and coming oil peaks,
Ocean wind harvesting is knocking at our door.

When I heard this it made my day. I have become discouraged about getting green energy legislation passed through Congress as of late. But this is refreshing news, though it is just the beginning. To those who oppose offshore wind projects I say the following. Consider the alternatives, transmitting wind from the Plains states to the East would foster the same kind of opposition, perhaps more intense. Bio-energy shows promise but can't meet all energy needs. Technologies like algae have much promise but are still young and pose many challenges. Solar energy too has a bright future, but photovoltaics must still come down more in price. I strongly support geothermal, but am uncertain about its potential in the East. Non-renewable resources cannot be immediately abandoned, but we must begin seriously turning away from them, especially coal. For most of us, myself included, going back to the days before electricity is a non-starter. So I believe offshore wind is the most promising source of energy for the East, though maybe not the Southeast, where I live. Advancing renewable energy in the Southeast is a must do but a definite challenge and something I hope this site will address more often.

The implications of the Cape Wind project means a great deal to the United States. As countries all around Europe have already installed many offshore wind farms, the United State has yet to really get any of its own projects in the water. No doubt, this project not only means big things for the communities near the project, but can serve as an example for future projects.

While there's no shortage of renewable energy resources throughout the USA, offshore wind energy can provide the most cost-effective electricity for coastal cities.

If we had legitimate elections, a sound monetary system, and a free and fair market-based economy, America would have achieved renewable energy independence a decade ago.

Appropriate RECs-based monetary reform can abolish the financial and economic distortions caused by the fraudulent private central banking monopoly and its addiction to the military-industrial complex.

With summer output of about 100MW, this may be the most expensive boondoggle in U.S. history. And get started on those NG peaker plants.

How many homes? It depends on where the homes are located, mild or harsh climate. Using a reasonable estimate of 1.5 KW per home, 130 turbines at 3.6 MW each times a 0.35 capacity factor, the power placed on the grid would be at a average rate of 163 MW. Divide 163 MW by 1.5KW equals 109,000 humes and that's all of their power KW needs. The grid is like a savings account that they deposit KWH and withdraw KWH as they need the energy.

I'm not sure where that '400,000' figure comes from. As a founding director of Clean Power Now, the Cape-based citizens' group formed to support this project, I've been close to the data for some years. The developer's claim has always been in the order of "75% of the average needs of the Cape & Islands". That's nowhere near 400,000 homes. Year-round, I think the area has 250,000 - 300,000 residents, so that would work out to maybe 100,000 homes. So that easily satisfies Marv's calculations above.

In reality, the power will be sold through a PPA with National Grid, so it's a semantic issue as to how many homes on Cape Cod the wind farm will power. What's important is how much fossil-generated power it will displace.

It will be interesting to see if the good citizens of the Cape & Islands now get upset because no-one's going to knock on their door to sell them clean energy directly.... to which Jim Gordon, head of Cape Wind Associates, might well respond, "where were all you people when the NIMBY opposition was putting me through the wringer for 9 years, including making personal attacks on my character?"

Seriously, Jim Gordon would never do that. He's too much of a gentleman. I'm not.

Grid, grid and more grid issues. How are the interconnection issues being dealt with and how much will it cost? Germany is finding out the ansewers are not always cheap or easy.

I also think that this is great news.
We are just begining a similar battle in Michigan to put offshore wind farms in lake Michigan.
The wind resource is very good.
Let's hope it does not take nine years here as well.

History in the making!

Billions spent on 468 MW.

Dead fish, dead birds fouled waters and it will never save consumers a dime.
Sure, it will make jobs, and create clean power, at what cost?
Would you sacrifice your children to make electricity? Of course not, it does seem that those who approved this venture have no problem with being the harbinger of death to thousands of god's creatures each year they are in operation.

What consumers will see is permanent devastation of the natural view from the shores of Cape Cod and higher future energy costs.

A solution will be available long time before they put one windmill in place. Prototypes developed and production models are currently being tested that will make this offshore project dead in the water.

Consumers will soon be able to buy homeowner unites that will produce 400% of their power needs right at home, this product will push the excess power into the grid and this will provide the consumer a dividend instead of a payment. This technology placed where the electricity consumed saves the environment and produces clean green power without killing animals or fouling the water.

In the time and for the money it will take to place these 130 windmills offshore this technology could be placed in 43,000 locations in and about where electricity is consumed and will power 1,075,000 homes where as this project Cape Wind power project will power one quarter that amount.

History is in the making!

Except that it won't power a quarter of a million homes, more like one tenth with some erratic power. That 468MW is nameplate capacity. All US wind in 2008 and 2009 averaged 24% of name plate. Off shore may do a little better. Denmark, Spain, and Germany are perhaps the most intense wind power countries. None has replaced a fossil fuel electric plant. Cape Wind is shaping up to be a multi-billion dollar fiasco.

"It will be interesting to see if the good citizens of the Cape & Islands now get upset because no-one's going to knock on their door to sell them clean energy directly...."

It is unlikely any Cape and Island citizens will care if you come knocking on their door to sell your power. The raw cost of electricity in the ISO NE SEMA zone has averaged 6.2¢ per kWh since March 2003. And, if you went back another 3 years and added the kWh charges from those years to the mix it would lower the cost to the high 5¢ range. Add in the ancillary costs, i.e. capacity, congestion, R.M.R. and you average about 9¢, which is approximately what the south shore is paying now with NSTAR. Your power is estimated to cost approximately 10¢ per kWh without the ancillary charges added. With consumers having the choice in Mass. to buy their power from any supplier they choose, it is doubtful they will decide to pay more when they can pay less. Approximately 50% of the electricity in NE is now generated using natural gas. With the abundant shale gas available from West Virginia to Canada, plus four LNG terminals and LNG tankers plying the waters looking for a place to off load, it is hard to believe our generation charges will raise much over the next 20 years. It is more likely that you will complete your project and have no home for your power than having people knocking at your door to buy the stuff.

The good people who are cheered-up by the decision on this project cannot be aware that it is a total scam. The cost of facing any given arrea of wind is a necklace-shaped function of (log) Diameter of Tuebine-Alternator Devices deployed. This is because T's cost/m^2 is directly proportional to diameter, while One A - to replace 4 of 1/4 the size - is about half that of the 4. So each time the diameter is doubled, the T-Bill doubles and the A-bill halves. There must therefore be a diameter - size - where the two are about equal. 1 Wad each, for instance. Cost of TADs n x (1+1) Wads
We can see that this will be the size of lowest cost. Try it out but replacing 4 with one of twice the size. Total cost is now n/4 x (8+2)
(Turbine costs 8 times as much, A costs twice as much)
which is 10/4 which is 2.5 Wads. If we do it again the cost becomes 4.25,
8.125 and so on. The size of lowest cost turns-out - after some 15 years research - to be about One metre in diameter. Just under this and the required gear-ratio can be 1:1. This, plus 3 other facts
2) Mode of operation - Const rps or Constant pitch, varying rps with wind
3) Betz limit for rotor placed in open air
4) Weathercocking of very large structures is ver problematic, and Also wind velocity changes over big distances - 40m for instance.
These factors combine to make current "technology nothing more than further environmental damage in the form of CO2 output from their creation. Eliminating only a fraction of One percent of fthis per annum, the things are no less than further environmental disaster. A sensible design of TAD can commonly return several whole percent p.a. of its cost and thereby a system can grow WITHOUT THE USE OF all the energy sources that "windfarms" purport to be replacing. They are as much use as a shot of junk.

bertwindon - comment # 16, interested in your comment, I'm with you right up to where you introduce the abbreviation, "Wad" as in
"1 Wad each, for instance. Cost of TADs n x (1+1) Wads",
Would you care to define "Wad" for me? - thanks - chris

" Denmark, Spain, and Germany are perhaps the most intense wind power countries. None has replaced a fossil fuel electric plant. Cape Wind is shaping up to be a multi-billion dollar fiasco. "

rolf-westgard-67277 : read before spouting crap

http://www.renewableenergyfocus.com/view/7092/wind-power-tops-new-eu-electricity/

The European Wind Energy Association (EWEA) says 39% of all new capacity installed in 2009 was wind power, followed by gas (26%) and solar photovoltaics (PV) (16%). Europe decommissioned more coal and nuclear capacity than it installed in 2009. Taken together, renewable energy technologies account for 61% of new power generating capacity in 2009.

http://www.windpowermonthly.com/news/986517/Iberdrola-outlines-renewables-expansion/?DCMP=ILC-SEARCH

Spanish electricity giant Iberdrola has announced plans to invest € 9 billion in renewables over the next three years, after recording a € 2.8 billion profit last year.

More than 100GW of offshore wind projects are under development in Europe, around 10% of the EU's electricity demand, and equivalent to about 100 large coal-fired plants.

Measuring generation sources by rated capacity is meaningless. You need to evaluate the capacity factor and capacity value.

Cape Wind LLC says that they will get a capacity factor of 39%, and cite the success of Denmark's Horns Rev and Horns Rev 2 wind farms. Unfortunately, no production numbers are published for individual wind farms in Denmark, but anyone can see and download the daily MW production of the DK-West and DK-East wind farm totals, from www.energinet.dk/en/menu/Market/Download+of+Market+Data/Download+of+Market+Data.htm . Selecting a years worth of data from 4/21/09 through 4/20/10 and averaging it, one finds that the rated 3180 of wind power capacity in DK-West is achieving a shopping 20% capacity factor. The average power output was 636.2 MWh, with a one sigma deviation of 505 MWh. (Those dates where the latest available when I ran the numbers a few days ago.)

For an excellent evaluation of wind's capacity value, review www.masterresource.org/2010/04/case-study-on-methods-of-industrial-scale-wind-powerii/

Lastly, when evaluating the subsidization of any particular energy source, one needs to normalize the subsidy dollars by the amount of energy produced, or the rated capacity times the capacity factor, in order to compare apples to apples.

We can cover all the roof tops with PV cells and wind turbines of the world, and this would be a awesome place to start, but unless we change the fossil fuel economy we are only building sand castles to be washed away! It is going to take many technologies to do this, but we have to address the problem at it's source! The place where most people get the energy to run their economies. I have been applying all I can, to solving the problem of renewable and sustainable energy. In recent months I have published my leading concept "Wind = Clean Green Energy". This concept will harvest more energy than conventional wind to electricity projects at a fraction of the cost. Rate payers will not see a change because the electric companies will be buying the fuel using the same infrastructure they use now, and use the same natural gas burning facilities they currently have in place. the difference will be in who they buy the fuel from and what gas they burn. I invite you to take a look at my work, and tell me what you think. And if I can help you in any way, please shoot me a Email. www.flickr.com/photos/kevinmoore001/sets/72157623631942524/
