Despite serving a valuable purpose to us all, tech companies have been criticized for years for their exorbitant energy consumption. Data centers are the backbone of the internet and keeping all that information just a click away requires a lot of electricity.
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.
The IT sector isn’t keeping up with its rapid growth,” says Gary Cook, the senior corporate campaigner on the Climate & Energy for Greenpeace. “More companies are making renewable energy commitments but energy demand growth by the industry is outstripping their renewable energy growth. 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.
Greening the Cloud with Renewable Energy
Google is leading the clean-energy revolution like no other company. It has invested in 22 renewable energy projects to date. In fact, Google is the biggest corporate purchaser globally of renewable energy, with a hand in utility-scale wind and solar projects that span the globe. Google has a goal to power 100 percent of its operations from renewable energy, and it is well on its way.
“We’re really trying to lead this transition to a cleaner energy economy,” said Michael Terrell, principal for energy and infrastructure at Google. “It’s transforming anyone who touches the energy space. It’s not just about data centers or tech companies.”
The Google approach to renewable energy is not unlike how many utilities purchase power. It often enters into power purchase agreements: long-term financial agreements, typically with wind farms, to buy power. The projects that Google has been involved with span the globe, including in Sweden, Iowa, Oklahoma and California, along with a recent $12 million investment in the largest solar energy project in South Africa.
