CEO and President, DONG Energy

Horns Rev II will be the world's largest offshore wind farm when it opens on September 17, 2009.

During CNN's "Going Green: Green Light for Business" coverage, we've asked businesses to tell us how they balance the imperative for profit with environmental concerns. Anders Eldrup, CEO and President of DONG Energy, tells us about the company's plans to switch its reliance from fossil fuels to renewable energy.

There are many reasons as to why coal today is the dominant fuel in power generation. In coal many countries found a way to alleviate the extreme dependence of Middle East oil after the 1970's oil crisis.

But the solutions of yesterday are not necessarily the solutions of today. We now know that fossil fuels are the prime contributors to global warming.

Today 85 percent of DONG Energy's production comes from fossil fuels, whereas 15 percent comes from carbon-neutral sources.

DONG Energy wants to turn the numbers around within one generation, so that 85 per cent of our energy production is carbon neutral. We call the vision 85/15.

At present we are formulating the strategy through which our vision will be achieved. The strategy is to create growth and reduce CO2 emissions at the same time, and key elements will be increased efficiency and more biomass and wind energy.

Efficient power plants
Energy efficiency is an often overlooked method of reducing emissions. DONG Energy's power plants rank among the most efficient with efficiency rates of up to 47 percent and we constantly work to improve efficiency. Furthermore, the central power plants are combined heating plants that channel excess heat from power production to consumers for domestic heating. Such use of energy elevates efficiency rates to 94 percent.

Biomass in power plants
To further bring down emissions high efficiency must be supplemented by renewable fuels such as biomass. Already today, Danish power plants use half of the straw from Danish agriculture in our power plants along with increasing quantities of wood chips and wood pellets.

Wind power works
Today, DONG Energy has built half of the world's offshore wind mills and wind energy will be an important contribution to achieving the 85/15 vision. Off the coast of Western Denmark, DONG Energy is completing the construction of the world's largest offshore wind farm, Horns Rev II. When it opens on the 17th of September this year, its 91 windmills will generate enough power to supply 200,000 households.

The offshore wind farm, London Array, in the Thames Estuary, will be another testimony to the potential of wind energy. DONG Energy owns 50 percent of the 1GW London Array project, which will be the world's largest offshore wind farm, powering 750,000 homes. First phase of the London Array is due to be completed by 2012.

Green transport
The uneasy companion of large quantities of wind power is great variation in power production due to the intermittency of wind. Electric cars can help absorb the surplus power production when energy production is high because of strong winds and when energy consumption is low at night. More electric cars simply mean more wind energy. In addition, electric cars can reduce the rapidly growing CO2-emissions from the transport sector. DONG Energy is developing the infrastructure and technology that will allow for cleaner and more intelligent forms of transportation.

But the approach to the transport sector has to be broad based. DONG Energy is building one of the world's first demonstration plants for second generation bioethanol in Denmark. Contrary to first generation bioethanol produced from food crops, second generation bioethanol is based on residual products from forestry and agriculture. The plant will produce 5.4 million liters of clean and affordable second generation bioethanol each year.

The role of politics
These are key elements in our strategy to simultaneously pursue growth and reduce CO2 emissions. But politicians must contribute by creating a political framework that aligns economic growth and climate mitigation. Concerns over growth and over climate change mitigation should not have to be balanced. They should be integrated.

On one hand, politicians must create economic incentives by ensuring a high price on CO2 and a global carbon trade system shared by all developed countries. On the other hand, politicians must formulate ambitious car-emissions standards, building codes etc. The first step towards aligning growth and climate concerns has to be taken in Copenhagen in December this year.

The UK's Foreiogn Office says foreign service staff should exercise caution on social-networking Web sites.

LONDON, England (CNN) -- Personal details and photographs of the incoming head of Britain's international spy agency have been posted on Facebook, British Foreign Secretary David Miliband acknowledged Sunday.

But he insisted that no compromising information had been revealed.

"You know he wears Speedo, swim, swimming, swimsuit... I mean what is that? I mean, that's not a state secret," Miliband said on a BBC Sunday morning talk show.

The man in question, John Sawers, is currently the British ambassador to the United Nations.

His wife posted details about their family, vacations and residence on the social-networking site, British media reported Sunday. Her Web site has since been taken down, reports said.

Sawers "was appointed 10 days ago to be the head of MI6," said Miliband, using the common term for the Secret Intelligence Service.

"He is an outstanding professional who will do a really good job in an outstanding organization that does a huge amount for this country," Miliband added. "The fact that there is a picture, the head of MI6 goes swimming. I mean, wow! That really is exciting. It is not a state secret."

But intelligence analyst Glenmore Trenear-Harvey said the leak was at least an embarrassment and possibly much worse.

"Have you ever seen the foreign secretary more embarrassed?" he asked rhetorically.

"The Foreign Office should have made the announcement that no personal details should have been left on any computer or directory," Trenear-Harvey told CNN.

The leak compromises Sawers' personal security, said Trenear-Harvey, the editor-in-chief of "The World Intelligence Review."

"You could have someone come online and insinuate themselves with Lady Sawers' daughter," who reportedly appeared on the Facebook Web site.

If she shares a computer with her father at home, "the house could pick up a virus, and once that happens we have access to the next chief of the Secret Intelligence Service," the analyst said.

An additional reason for red faces is that Sawers will be in charge of a new British cybersecurity organization when he becomes head of MI6, Trenear-Harvey pointed out.

The new organization, based at GCHQ, another British intelligence agency, will be "charged with making sure that all the intelligence services are not vulnerable to hacking, identity theft, or phishing," Trenear-Harvey said.

This is not the first time a top British intelligence official's personal details have been leaked.

When Richard Dearlove became the head of MI6 in 1999, "his address in Putney was announced," forcing the government to put Special Branch police officers there to protect him, Trenear-Harvey said.

And when Stella Rimington became the first publicly named head of MI5, the domestic security agency, in 1991, her north London address was revealed.

"She and her daughter fled the house and were put into an MI5 safe house," Trenear-Harvey said.

Foreign service officers "are advised to exercise caution" on social-networking Web sites, a Foreign Office representative said, declining to be named, in line with government policy.

Sawers, 53, is a career foreign policy expert. He was a foreign policy adviser to Tony Blair when Blair was prime minister, then became ambassador to Egypt and briefly represented Britain in Iraq. He was political director at the Foreign Office for four years before going to the United Nations in 2007, according to his biography on the Web site of the British mission to the U.N.

He is slated to replace John Scarlett in November as head of MI6.

As chief of SIS, he reports to the foreign secretary, according to the SIS Web site.

"Known as the Chief of SIS or 'C' (after the first Chief, Mansfield Smith Cumming, who signed himself 'C'), the Chief is the only serving member of the Service who is officially named in public," according to the agency.

Facebook claims to have "over 200 million active users."

Editor, Air Transport Intelligence

Relatives and friends of an Air France steward follow his coffin during his funeral last week in Rio de Janeiro.

Brazilian Navy officers hold a wreath during a tribute held on Monday to victims of Air France Flight 447.

The tail fin of the Airbus A330 that crashed in the Atlantic is unloaded in Brazil earlier this month.

(CNN) -- If there was ever any question over the importance of finding the black boxes from Air France flight 447 then there is certainly none now.

Most of what we heard from Thursday's briefing by the investigating team only serves to deepen the mystery behind the loss of the Airbus A330.

Lead investigator Alain Bouillard sums matters up when he says: "As of today we are far from having any real idea of the causes of this accident."

Consider what we now know. The aircraft was cruising in an area in which other aircraft were successfully managing to avoid the worst of the storms. It did however suffer "inconsistent" speed indications to the pilots and its computers and this is an aircraft type with a known history of such problems.

But even if the aircraft penetrated deep into the storm, it didn't break up in the air. Instead, at some point it seems the crew lost control of this state-of-the-art, highly-automated aircraft in unknown circumstances. And it then followed what must have been a horrific trajectory down to the ocean nearly seven miles below which it finally struck belly-first, crushing internal structures.

The current evidence sheds little light on those terrible minutes. We still don't know why the aircraft was as close to the storm as it was, or what caused the malfunctioning speed indications. We don't know if it was damaged by lightning or turbulence or even if it was damaged at all. Perhaps the crew was simply unable to fly the aircraft in the darkness, severe turbulence and possibly cloud without the vital airspeed data.

We don't in fact know who was flying the aircraft -- it is a curiosity that the captain's body is among the relatively few found so far. Perhaps he was taking his authorized rest as the aircraft headed over the ocean in line with normal procedure and so was not in the cockpit at all as the remaining two pilots flew the aircraft.

Some facts that we learned are not so surprising and caution is needed in drawing conclusions from them. It's confirmed that there was no emergency call, but not only is it a common feature of accidents that pilots don't make a call, but we now hear that radio communications on the night had been hopelessly difficult throughout, perhaps making it seem even less worthwhile for them to bother with it.

The investigators tell us that no inflated lifejackets have been recovered, but imagine the situation in the cabin. Not only did the passengers have no reason to expect to ditch, but with the aircraft out of control it may have been impossible for them to reach them due to high G-forces.

So what now? There have been conflicting views about how long the pinger signal from the black boxes will last after the nominal 30 days is up. Bouillard gave his view --- it could be another 10 days, although maybe it's stopped already of course.

So the search continues with submarines and tethered robots until July 10. Then new techniques are required to physically look for wreckage, and hopefully the black boxes, on the ocean floor. That is likely to involve an autonomously guided unmanned minisub which can patrol at some 5,000 meters depth sending back sonar images, and can then be moved in to investigate objects of interest by video link.

But if the flight data recorder in particular is not found then the air transport industry is staring at the deeply worrying prospect of permanently living with the unexplained loss of one of the world's most modern aircraft.
