Buying Video Games on Disc Is
More Energy Efficient than Downloading
PlayStation game console and Blu-ray disc
Downloading video games from the Internet creates a larger carbon footprint than driving to the store to purchase the same game on a Blu-ray disc, according to findings published in the Journal of Industrial Ecology
. For an 8.8-gigabyte PlayStation video game file — the average size of video games in 2010 — the resources required to produce, distribute, and dispose of Blu-ray discs are far less than the energy required to power servers, routers, and networks involved in downloading the game file, researchers say. The advantages of discs decrease as file sizes shrink, the analysis found, and for game files less than 1.3 gigabytes, downloading has a smaller carbon footprint than purchasing the game on Blu-ray. Between 2010 and 2013, however, game file sizes actually doubled for PlayStation4 and increased by 25 percent for PlayStation3. The analysis illustrates why it is not always true that digital distribution of media will have lower carbon emissions than distribution by physical means, especially when file sizes are large, the researchers say.
