Cloud computing championed by Amazon and other tech companies is using -- and wasting -- a lot of energy, and leading to pollution

All your emails, Youtube videos and Facebook posts are using a ton of energy, and creating a lot of pollution.
A new investigation by the New York Times finds the data centers that power the Internet – and more and more, the entire economy – churn through the output of 30 nuclear power plants.
More from the must-read article:

Worldwide, the digital warehouses use about 30 billion watts of electricity, roughly equivalent to the output of 30 nuclear power plants, according to estimates industry experts compiled for The Times. Data centers in the United States account for one-quarter to one-third of that load, the estimates show.
“It’s staggering for most people, even people in the industry, to understand the numbers, the sheer size of these systems,” said Peter Gross, who helped design hundreds of data centers. “A single data center can take more power than a medium-size town.”
Energy efficiency varies widely from company to company. But at the request of The Times, the consulting firm McKinsey & Company analyzed energy use by data centers and found that, on average, they were using only 6 percent to 12 percent of the electricity powering their servers to perform computations. The rest was essentially used to keep servers idling and ready in case of a surge in activity that could slow or crash their operations.
