Facebook shares green technology

8 April 2011 Last updated at 23:45 GMT By Maggie Shiels Technology reporter, BBC News, Silicon Valley Facebook servers in data centre Facebook claims that its data centre uses far less power than its rivals' facilities Facebook has announced that it will share the design secrets behind its new energy-efficient data centre with rival companies.

The social network's facility in Prineville, Oregon is said to use 38% less power than existing centres.

It hopes, by making the innovations public, to cut the amount of electricity the industry consumes.

Despite Facebook's advances, some environmental groups have criticised the firm over its green credentials.

Working under the title Open Compute Project, Facebook will release specifications and mechanical drawings of the building and its servers.

"It's time to stop treating data centres like Fight Club [do not talk about them]," said Jonathan Heiliger, the company's vice president of technical operations.

His comments are likely to be interpreted as a dig at other web firms, such as Google, Twitter and Amazon which have kept their own designs under wraps.

Power hungry

Data centres use vast amounts of electricity to run their computer equipment and also to keep it cool.

Environmental group Greenpeace has estimated that their total global energy use will have reached 2 trillion kw/h by 2020.

Until now, Facebook has paid to lease its servers and storage space from other companies.

The Prineville plant is its first custom-built facility and cost $188m (£117m). Much has been made of its environmentally friendly specifications.

Among the innovations, the centre make extensive use of outside air, as opposed to air conditioning, to cool the rows of servers.

The machines themselves are also specially designed to maximise the new cooling system.

"The best way to reduce CO2 and improve the environment is to cut energy consumption and that is what we are doing," said Mr Heiliger.

Facebook has stripped out nonessential parts, paint, logos and stickers - saving, it claims, more than 6 pounds of materials per server.

However, Greenpeace said the company could have gone further to prove its commitment to sustainability.

"If Facebook wants to be a truly green company, it needs to reduce its gas emissions," said Casey Harrell, a climate campaigner.

"The way to do that is decouple its growth from its emissions footprint by using clean, renewable energy to power its business instead of dirty coal and dangerous nuclear power."

Greenpeace launched a campaign last year calling on Facebook to stop powering its business with energy from suppliers that use coal.

More than 101,000 Facebook users have so far clicked the "like" button on Greenpeace's campaign, dubbed "Facebook: Unfriend Coal" .

End Quote Jonathan Heiliger Vice Pres. Technical Operations, Facebook As well as saving money on power, the company said that running its own data centre would help it to push through future changes on the site.

"We found a lot of stuff mass manufacturers were putting out wasn't what we needed, so we customised it to better fit social applications," said Facebook founder Mark Zuckerberg.

Jonathan Heiliger explained further: "Having this control over our infrastructure gives us a ton of flexibility especially when turning on a new feature.

"Live commenting or searching for friends of friends requires this massive amount of computing and the fact we can do this and innovate and have all this control gives our engineers the flexibility to develop those products that wouldn't exist potentially."

Money and power

Facebook claims that, by sharing its design innovations, the wider web economy will benefit, especially small start-up companies.

Social gaming firm Zynga said it was looking at perhaps using some of the designs, while computer maker Dell said it definitely would.

"It's a very important step in helping the industry drive efficiency end-to-end," Forrest Norrod, Dell's vice president of servers told BBC News.

"This project is also very important in promoting the understanding of this technology and presents an opportunity to turbo charge innovation around data centre efficiency."

Dell announced that it plans to spend $1bn (£600m) building 10 data centres around the world.

The PC manufacturer is a partner in the Open Compute Project along with HP, AMD and Intel.

Rackspace, which manages servers for smaller companies, believes the cost savings cannot be ignored.

"This is a huge leap forward and will save millions and millions of dollars," said Graham Weston, chairman of Rackspace.

"A good sized data centre probably spends about $10m a year on power and these new designs should drive down that cost by about 40% or $4m."

Facebook claimed that if one quarter of US data centres used specifications released by the Open Compute Project, the energy saved could power more than 160,000 homes.

Blue, not green

While Facebook hopes to make significant savings with its new data centre, the company has not been penny-pinching completely.

One area the team splurged on was lighting for the servers.

Engineer Amir Michael said he wanted to use blue LEDs but was told they cost 7 cents each, compared to green ones which were 2 cents per LED.

He opted for the blue ones anyway.

"I thought it would be really cool if the data centre glowed in blue. It's a pretty big environment and I wanted to add a little bit of character, a little bit of style to it," said Mr Michael.

Green economies to grow, says UN

21 February 2011 Last updated at 10:01 GMT Traffic on a highway (Image: Reuters) The current "brown" economy is carbon and resource intensive and is not sustainable, the study says Investing $1.3 trillion (£800bn) each year in green sectors would deliver long-term stability in the global economy, a UN report has suggested.

Spending about 2% of global GDP in 10 key areas would kick-start a "low carbon, resource efficient green economy", the authors observed.

They also recommended following policies that decoupled economic growth from intensive consumption.

The findings have been published at a meeting attended by 100 ministers.

"Governments have a central role in changing laws and policies, and in investing public money in public wealth to make the transition possible," said Pavan Sukhdev, head of the UN Environment Programme's (Unep) Green Economy Initiative.

"Misallocation of capital is at the centre of the world's current dilemmas and there are fast actions that can be taken, starting literally today," he added.

"From phasing down and phasing out the $600bn global fossil fuel subsidies, to re-directing more than $20bn subsidies perversely rewarding those in unsustainable fisheries."

Unep defined a "green economy" as one that resulted in "improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities".

When it came to investing 2% of GDP in greening the global economy, the authors recommended a number of investments, including:

$108bn greening agriculture, such as encouraging and supporting smallholder farms$134bn on the building sector, including improving energy efficiency$110bn improving fisheries, including reducing the capacity of the world's fishing fleet$15bn on forestry, with "important knock-on benefits for combating climate change"Almost of $110bn on both water and waste, including sanitation and recycling

The report, produced by experts from developed and developing nations, suggests that the green economy model would deliver higher annual growth rates within 5-10 years than a business-as-usual scenario.

In order to unlock the level of investment required, it added that it was necessary to reform existing national and international policies.

"The green economy - as documented and illustrated in the report - offers a focused and pragmatic assessment of how countries, communities and corporations have begun to make a transition towards a more sustainable pattern of consumption and production," said Unep executive director Achim Steiner.

"With 2.5bn people living on less than $2-a-day and with more than two billion people being added to the global population by 2050, it is clear that we must continue to develop and grow our economies.

"But this development cannot come at the expense of the very life support systems on land, in the oceans or in the atmosphere that sustain our economies, and thus, the lives of each and everyone of us."

The findings are being published at the 26th session of Unep's Governing Council/Global Ministerial Environmental Forum, which is being held in Nairobi, Kenya, until 24 February.
