Here's a startling statistic: If all the cloud computing services in the world were an actual country, that nation would be the about the sixth-largest electric power consumer in the world.
NPR reports that researchers at Greenpeace place the cloud right after Germany and before Russia.
That staggering volume of power consumption is driven by the massive data centers that store data around the world, allowing users to pull up documents and apps anywhere. The New York Times reported that in 2012 the cloud consumed 30 billion watts of power, as much as is produced by 30 nuclear power stations.
This has already led to some drastic measures by big data center users. Facebook has located a data center just outside the Arctic Circle to take advantage of the naturally cooling temperatures. Apple Inc. (Nasdaq: AAPL) now powers its cloud with a mix of solar, hydro-electric and wind-generated electricity.
The trend towards more distributed data centers might make it easier to co-locate the storage end of the data center with solar power set-ups, wind farms and hydro-electric power plants. The front-end servers and a fast connection would be in urban areas, while the storage would be in rural areas where it easier to find and fund a power source. (See Reliance Rebrands With Its Head in the Cloud.)
Nonethless, it's worth asking just how we'll keep powering the cloud as it continues to get bigger.

Re: Big v small And Dennis I would add we need to keep up with technology.
Let me give you an example: http://engineering.osu.edu/news/2013/06/ohio-state-pushes-clean-coal-technology-ahead
This could make coal of all things one of the best sources of clean energy that we have. I think assuming that technology won't change all of this is bad. If I use nuclear as an example, I lived in South Florida for about 15 years. Turkey Point Nuclear Plant took nearly a direct hit from Hurricane Andrew and was just fine. The Japanese plants got hit with their issues and that was a problem.

Re: Big v small We've lived with nuclear power for more than a half-century now. Without it, our world would not be what it is, for good and bad. We are now 99.8% dependent on electric power to function as a society. So we're kind of stuck with it.

Re: Big v small I was with you all the way... until you brought up nuclear...
Let's keep that one out until someone figures out how to neutralize nuclear waste... you really don't want to leave in a 2mile radius from a nuclear plant, and you don't want a nuclear waste facility in your backyard either, so what would you do?

Re: Big v small This has always been my concern about outsourcing Power Consumption and Carbon Footprint along with it. Once the enterprise relies on the outsourced data center, the power consumption goes to the cloud service provider, and so does the CFP. Same happens when you promote other interesting green initiatives such as Working from Home. The CFP is transfered to the employee who has to get power/cooling/heating under their roof to work, along with the extra networking needs (which also require power) to get vpn'd to work.
Question is, does the cloud need to be the giant we're building today, or can we live with less?

Re: Big v small @mendyk: Yes, it's relatively small area overall -- and I imagine the management and politics involved would probably keep it from being efficient for awhile unless everyone got on board. One or two parking lots wouldn't amount to much -- but it could be a different story entirely if all the lots or entire stretches of highways had solar panels overhead.

Re: Big v small The solar farms now being created generally are being built on open land -- as is the case with Apple's two farms in North Carolina. Using barren land like deserts also is happening, and that makes sense. And I also agree that installing panels on developed properties is a good idea -- but that will provide a small percentage of the power we now require.

Re: Big v small Dennis,
Hydro is considered such an environmental issue that nobody (in the US anyway) is building new Hydro power. Solar has the capital and space issues. Wind has space, sightlines, and killing birds issues. Both wind and solar have storage issues. Nuclear has waste and other safety concerns. Fossil fuels have global warming issues.
And of course costs are not equal between sources: http://en.wikipedia.org/wiki/Cost_of_electricity_by_source
Light Reading’s Upskill U is a FREE, interactive, online educational resource that delivers must-have education on themes that relate to the overall business transformation taking place in the communications industry.

Six different communications service providers join to debate their visions of the future CSP, following a landmark presentation from AT&T on its massive virtualization efforts and a look back on where the telecom industry has been and where it's going from two industry veterans.
At Light Reading's NFV & Carrier SDN event in Denver, Ray Watson, vice president of Global Technology at Masergy, says that because of the growth in virtualization, the threat landscape is shifting in favor of the attackers. As a result, service providers need to think beyond just defending the perimeter and take a more holistic approach to security.
At September's NFV & Carrier SDN event in Denver, Light Reading sat down with Victoria Lonker, director of Product and New Business Innovation at Verizon, to chat about where the carrier is with delivering virtualized services to business customers.
Nick Thomas, practice leader of digital media at Ovum, talks about how digital transformation in the technology, media and telecom sectors will enable the development of a new range of applications and services for enterprises and consumers and how the upcoming Digital Futures event in London will examine ...
Heavy Reading Senior Analyst Jim Hodges speaks with Accenture's Larry Socher and Matt Anderson about what service providers must do to transform their business to get the benefits of SDN and NFV including: leveraging DevOps, introducing real-time OSS and implementing analytics.
VeEX's Senior Director of Business Development, Perry Romano, explains how VeEX provides tools to help install, maintain, monitor and manage network infrastructure efficiently and effectively. The portfolio of products on display include the RXT-6000, MTTplus and TX300s.
Light Reading Editor Mitch Wagner talks to NetScout CMO Jim McNiel about maximizing the benefits of enterprise cloud and digital transformation while minimizing potential pitfalls with a proper monitoring and instrumentation strategy.
Many of the initial use case implementations are single-vendor and self-contained. The industry is still climbing the virtualization maturity curve, needing further clarity and stability in the NFV infrastructure (NFVi) and greater availability and choice of virtualized network functions (VNFs). Interoperability between NFVis and VNFs from different vendors ...
Join us for an in-depth interview between Steve Saunders of Light Reading and Alexis Black Bjorlin of Intel as they discuss the release of the company's Silicon Photonics platform, its performance, long-term prospects, customer expectations and much more.
A vital part of increasing the number of women in comms is transforming the ways companies can support and empower women. While progressive company policies that support both men and women in achieving work-life balance are a step in the right direction, creating a company culture that supports those policies can at times be more challenging.
During this show, we'll talk to Lynn Comp, Senior Director of Industry and Sales Enabling (ISE) in the Network Platforms Group at Intel, about why those challenges exist and how companies can overcome them. She'll provide insight into how Intel has worked to create a culture that supports work-life balance, and provide steps and guidance for other companies wishing to do the same. We will also leave plenty of time to get your questions answered live on the air.
