...oh! where to begin....

to get to the point:
This giant turbine was upgraded, so that instead of generating 4.5 megawatts, it now produces 6 megawatts — that's enough to supply power to 4000 homes in Germany.

Notice it says ‘homes’ not individual people. So, how many homes or households are there on average in the out islands?

Total Population by Sex and by Island and Number of Households (200?)

Looking at this fairly recent survey, even if the amount has DOUBLED since the time of the survey, the following islands would only need at most TWO of these to supply power to all residences on the island.

There is a lot of resistance here to any kind of renewable energy (other than solar heaters).

According to BEC, there is not enough wind in the Bahamas (outside of parliament) to justify a wind farm. And more exotic projects like OTEC are very capital intensive and unproved commercially.

Of course, economics and technologies change every year.

@Larry:
that's why we should be taking advantage of the fact that the population on the family islands is so small. They're size is perfect for inviting some of the companies behind these technologies to come here and set up some test facilities. The local residents will get cheap power, the companies will pay the government a license fee, the country will get free publicity, heck, the settlements might even get a few tourists who want to check out the power plant.

And there's a dozen other options besides just plain wind farms. And notice, thinsoldier's links only mention a SINGLE windmill powering that many homes. That doesn't count as a "Farm".

And BEC is wrong about the amount of wind but it is true it isn't always blowing in the right place at the right speed so it's not like a windmill or any other alternative energy will be putting BEC out of business soon.

If they were wise they'd put the technology in place themselves, take the millions they save on fuel and pay off whatever debts they may have to the unions or whatever else, give everybody a tiny raise to kill all valid reasons for any future strikes and charge their customers ...a little less, not a lot less, so that they can still rake in huge profits and HNIC's can pocket vast amounts of money to retire with.

It's a perfect plan.
Any employees complaining about overtime pay they still havent gotten will get paid.
The public will have for once a consistent supply of energy for a noticeably lower price (but not too low)
Any evil crooks at the top of the company can fulfill their evil and crooked desires since there's so much money left over from not having to buy fuel.
We'll be benefitting the environment and setting an example for other Caribbean nations and the foreigners will have something good to say about The Bahamas for once.

Re: Out Island Populations Contribution:
There exists a glossy Public Lands chart with the 1000 meter water depth line drawn throughout the Bahamas.It is interesting to note where the cold water pipe (The costliest part of OTEC) can be kept short.(e.g. Look 1/3rd
the way from Hole In The Wall to Sandy Point.) I believe west side San Sal may be another. Unless you can reach 3200 feet depth in a short distance, forget it.

OTEC has by-products that far outvalue the energy component.

E. P. Taylor knew that as did Dillingham and the others. One of the by-products is huge quantities of potable water.

The replacement of singlehull petro-tankers around the world makes the plant platform, briefly, very economical. The internal equipment of OTEC is found in almost all large commercial powerplants. The vertical "pipe" now available as a single extrusion, was unavailable 10 years ago.

Www.caribotec.com suggests a location a little further south to provide six countries with agricultural quantities of fresh water.

The peaking and decline of the extraction rate of our planet's fossil fuels demands our attention. It may also behoove us to realize and stop human induced catastrophic climate changes... the alternative is extinction.

OTEC is one of the most benign long term energy, water, fertilizer, and mineral strategies. Solar, wind, and local organic biomass surplus, are also good where applicable. We need every answer as oil and other fossil fuels become expensive and scarce, every answer to mitigate climate forcing. The total answer is a mosaic of solutions.

OTEC has the intrinsic advantage of self contained energy storage, and the ability to supply continuous electrical base loads regardless of diurnal rhythms or uncertain winds. OTEC is a scalable technology that taps a source of renewable energy and clean water with greater capacity than our foreseeable needs.

Standard economic analysis breaks down and fails when it does not include the price of our extinction. We need to approach this differently.
