Building on the original work, this study evaluates the energy use of 26 gaming systems (PCs, consoles, and media streaming devices), including energy use as it varies by game, choice of VR, and a first-ever look at cloud-based gaming.

The study that started it all!  Presents a novel analysis of the energy use of gaming PCs and opportunities to improve efficiency.

We also have a number of geekier studies that you might be interested in.
