A transition to renewable sources is underway, which cloud users can encourage by choosing their online service providers that source clean energy.


The ‘Dirty Cloud’
Data centers use up to 3 percent of all U.S. electricity and the information technology sector is responsible for 7 percent of global electricity consumption. The term “dirty cloud” was even coined to refer to the coal and other high-emissions fuel sources that power cloud computing. Global internet traffic has tripled in the last four years and it is anticipated to triple again by 2022, according to the International Energy Association.

This is an urgent issue to address the use of fossil fuels given the climate crisis.”

​Since 2009, Greenpeace has been putting pressure on some of the more polluting tech companies while praising greener ones. When examining the energy footprint of tech companies, some clearly lead the way in the corporate use of renewable energy deployment, energy transparency, advocacy, and energy efficiency innovations.
