Project cost $2.84B USD, exploits natural abundance of marine winds

Britain's miles of coasts are home to some of the world's most active marine winds, making them a prime place for offshore wind power.  The nation this week announced the opening of the world's largest marine wind farm installation, a monstrous 630 Megawatt, 175-turbine design dubbed "the London Array".

I. London Array is Turned On

The new farm is the latest bump for the UK, which has more installed offshore wind capacity than any other nation in the world.  The UK currently gets 12 percent of its energy from renewable energy, but it hopes to expand that to 30 percent by 2020.  New offshore wind installations are critical to that goal.

The new farm is located along the coastal border of Kent and Essex, to the northeast of London, facing the North Sea.  It uses Siemens AG's (ETR:SIE) SWT-3.6-120 turbines [PDF] (3.6 MW), which has three blades and a diameter of 117 meters.  The turbines are installed 20 kilometers (~12.4 miles) off the coast.

Here's some videos of the plans and construction of the farm and supporting substation.

The groups have petitioned to expand the installation to 870 MW, adding another 66 turbines to the current count.

II. Green Profit, But Energy Firms are Hungry for More

The new installation is a joint venture owned by Germany's E.ON SE (ETR:EOAN) (30% stake), United Arab Emirates' state-owned Masdar Abu Dhabi Future Energy Comp. (20% stake) and Danish state-owned Dong Energy A/S (50% stake).  It cost a whopping €2.2B ($2.84B USD) to build, but is expected to power a half million homes for at least 30 years.  

Its total annual generation is estimated by the developers to be 2.1 terawatt-hours (tWh) per year, but perhaps a more realistic metric would be 1.65 tWh, if you take the average capacity factor (29.6 percent) of UK offshore wind farms last year.

UK energy costs around 15 pence ($0.23 USD) per kWh [source], so this works out to somewhere between $379.5-483M USD in revenue per year, or roughly $11.4-14.5B USD in revenue over a 30-year lifespan.  However, Prime Minister David Cameron recently announced that the government would mandate incentives to drive the revenue per kWh to three times the base rate, which would be mean over $1B USD in revenue per year.

The UK has 3.3 GW worth of installed offshore wind capacity.  EON estimates the new farm will save 900,000 tons of carbon emissions per year.

While it appears to be a booming era for UK offshore wind, the manufacturers and energy companies are a bit disgruntled at the lack of longer term guarantees from the UK central government.  They wanted plans to run through 2030, but only got targets for 2020.

Greenpeace Executive Director John Sauven tells Bloomberg, "[David Cameron's administration] needs to give the sector long-term certainty by agreeing to cut carbon completely from our electricity sector."

We (Americans) know how the geopolitical landscape of Europe works

Not all of you do. I've witnessed the ignorance first hand.

quote: Adjective Of, provided by, or concerned with the civil government of a country : "the future of state education".

If this was the only definition of 'state' - then none of your states are states, since none of them govern a country. That's the whole point - there are two meanings but nobody in the UK would ever use the word 'state' to describe our country.

You seem to think that it only applies to subunits of a federation

I don't recall stating this. I simply don't like using the same word with two different meanings. American people shouldn't refer to countries as states because states mean something different in the US.

Have you never heard of a state dinner? The state car? Matters of state? And here you were implicitly belittling American's education.

If you were sufficiently educated you wouldn't have incorrectly inferred things I didn't claim and would therefore realise the irrelevance and irony of your entire final paragraph.

Generalizing about an entire nation's population based on isolated experiences is usually considered beneath enlightened civilization such as the one you purportedly have in Europe.

I think they would, but even if they didn't it is still valid usage. Just because the USA subdivides itself into units called states instead of provinces, counties, boroughs, shires or parishes has no effect on the international use of the term state as having to do with a country's government.
I don't recall stating this.
You did with your Texas comment.

Educated doesn't mean clairvoyant.

In any case, the American usage dates from a time when we were a confederation much like your beloved European Union. The Articles of Confederation did indeed unite independent nations and the term state used then was perfectly accurate: describing a country. The colonies were each separate sovereign units before the constitution was ratified.

I'm English and I can't think of a time I have ever heard anyone refer to the UK as a state. Not in person, on the radio, on TV or even in writing until today.

"The UK is a state" sounds just as silly as "the USA is a state". You'd refer to both as a country, wouldn't you?

I'm English as well, though had I known the simple use of the word "state" would be much to others' chagrin, I'd have been content to just put "The UK is devolved" or simply that the UK wasn't a federation.

Certainly less amusing than putting "devolved union" or "devolved archipelago".

Really? You've never heard of the term "Nation State", "Sovereign state", or in the UK's case "failed state"? :D

And, some proof of my hunch that state is used as expected in the UK:

You have state pensions and state visits, does that not make you a state?

Except that actually doesn't prove the point you're trying to make at all, since a 'state pension' is not an example of someone referring to the UK as a state. It's simply a label given to a particular pension scheme. And either way, the objection which was clearly being voiced was US usage of the word 'state' to refer to the UK due to it's secondary (and most common interpretation) meaning.

The second link is simply a result of an international convention to describe visits between foreign heads of state as 'state visits' - it does nothing whatsoever to indicate what British people call their own country.

You are state and country; deal with it!
