There are currently only two credible estimates for global data center energy consumption: 196 TWh to 400 TWh for 2020. Why do we see vastly higher reports?

Sustainable computing concerns the consumption of computing resources in a way that means such usage has a net zero impact on the environment.

What will drive computer performance after Moore’s law? Will programmers need to focus on performance or can ARM chips and the cloud save us?

It is currently impossible to properly compare how “sustainable” one product is vs another. Pictures of wind farms look nice, but how do you choose which cloud region to deploy (or move) your resources if there is no way to compare them?

As more applications are run through a web browser, even that is beginning to be streamed from the cloud. Is that the best use of our now highly efficient computers? How energy efficient is application streaming?

Services shipped with Windows 95 no longer work – ICQ, AOL Messenger, MSN. All shut down. But how likely is that today?

To avoid accusations of greenwashing, data center operators must consider investing in a portfolio of renewable energy products. RECs cannot credibly be used to back claims of 100% renewable energy use.
