Slowly "the cloud" is turning green. Amazon, Google, Microsoft, and Apple all have pledges to become carbon neutral within the next few years. Prior to 2016 we were in a similar situation, with "dirty" coal and gas being part of our power mix. We chose to offset our emissions with local schemes and grew our support for local environmental projects.
In 2016 we achieved our goal: now all our servers are hosted within datacentres powered by renewable energy. Everything we offer is now powered by wind, by water, and by other environmentally friendly sources.
