Don't agree that offshore wind will be of much benefit nearterm. Commercial wind is all about LCOE, and offshore wind is still far more costly than onshore installations.

It would be more productive to focus efforts on increasing the size and efficiency of onshore turbines. The US midwest (Wyoming, Texas, South Dakota, Colorado) is blessed with massive amounts of acreage having prime wind conditions. While it wouldn't be as "sexy" as pushing offshore wind, it would be far more cost effective to focus on developing these inland regions.

The writer laments the fact that getting government approvals for building an offshore wind farm in the US is next-to-impossible. But then applauds the very same bureaucrats that created the problem for proposing even more regulations to try to solve it.

Unfortunately, offshore wind farms in the US will continue to face regulatory roadblocks for years to come. It is a political situation where one environmental group (renewable energy proponents) is pitted against another group (like the California Coastal Commission).

First it was on shore wind farms in US and in the coming years it will be more off shore with large wind turbines.

Simple question: do you wanna.

Only 4 states do not have advisories for consumption of fish due to mercury and other heavy metals; 16 have blanket advisories. More than half of the problem can be traced to one source. Note to 'environmentalists' - you can't say you don't inhale.

@ anonymous - the economics of offshore wind is a balance of quality of resource versus cost. At the end of the day its a matter of (total energy produced)/(total cost of production). Generally, off-shore resources are better than onshore. Access to market is another consideration: Wyoming might be a very fine place but it's rather far from Boston and the substantial number of independent system operators and unregulated territories inbetween presents a logistic and commercial nightmare. Potential interoperability between Wyoming's unorganized power district and ISO New England is nil.
When you view the North American power system as a whole, it is anything but unified or united - supergrid could be 100 years away.

It's easier than ever to see where such sites should be placed, using GIS tools - http://www.marinecadastre.gov/MMC%20Pages/tools.aspx

I read a scientific american article a year or two ago that suggested that a hoop could be attached the the turbines that has long chains hanging off it to grow oysters. With oysters going for $70 per half bushel, it seems like there is money to be made there. Oysters could be collected when maintenance needs to be done on the turbines, so there shouldn't be too much extra cost. Then again I know very little about the oyster industry, but this seems like a pretty good way to help cover costs.

At this stage of development wind energy is an impotent component in our power grids. The unpredictable nature of wind energy must be supplemented with fossil fuel power stations. It has been found that this practice reduces efficiency to the point where no fuel is saved and no carbon emissions are reduced.

In view of these findings, wind energy projects are a redundant and unnecessary add-on to the power grid. The missing component is utility scale energy storage. Until someone comes up with a viable solution that can convert wind energy into a potent power source connected to the grid, wind energy is an unnecessary burden to the national economy.

GeraldR,

Yes, typical offshore wind conditions are somewhat better than on-shore. But an off-shore turbine installation costs about 50% more than on-shore. And since turbine capital costs are the main driver in LCOE, on-shore currently still makes more sense. The scale of on-shore turbine designs is also getting larger. So that advantage in off-shore turbines is going away.

As for resource location, think about it this way: It's much more practical to move the large industrial users of electricity to remote, low-cost, wind-rich areas like Wyoming, north Texas, or south Dakota, than it is to install lots of off-shore wind turbines in places like Cape Cod or Long Island.
