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."

HIV can be cured for as little as 40 cents a day.

There is no cure for HIV. But there is hope for you, maybe in a few years

Sure, there's no specific bottle labelled "the cure", but two men underwent bone marrow transplants and were miraculously cured of HIV.

I imagine you may be referring to this.

No, they've been able to cure HIV for decades. The only problem was cost and it wasn't 100%.

The organizer suggested they film a documentary in AIDS clinics in Zambia, where one out of seven people is HIV-positive, and one person's daily dose of antiretroviral drugs costs about 40 cents according to (RED) – a cost which many patients are unable to afford

The cost is actually ballooned because of the our society is set up. But 40 cents a day could help cure people with HIV. Not 100% but it's pretty good rate. Magic Johnson didn't live because there wasn't any cure. He's completely cured now and even though he got it years ago. Antiretroviral shots or "cocktails" used to cost 125k a pop and only the rich people can afford it. You don't hear about it because nobody wants to tell the world they got AIDS.

Antiretroviral medication does not cure the condition of being HIV positive, but it does most often prevent the most severe symptoms. Thus the persons are not "cured" in the strictest meaning of the word, but they are kept alive and mainly healthy.

Magic Johnson, as anybody else who lives with HIV, still takes a daily dose of medication, and will continue to do so for the rest of his life.

Of course that does not change the sad fact that the profit expectations of western pharmaceutical companies is incompatible with the current economical situation of most African states.
