The Hungry, Hungry Cloud
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.

Nonethless, it's worth asking just how we'll keep powering the cloud as it continues to get bigger.
