Streaming or downloading 12 tracks, without compression, just 27 times by one user would, in energy terms, equate to the production and shipping of one physical 12-track CD album.
In other words, repeated streaming of favourite tracks might not be a desirable long-term media solution. Fortunately some apps — like Spotify — feature a local caching feature, which avoids repeatedly streaming the same song over and over.
But what about the fact that teenagers use YouTube as their main music source these days? The mighty ‘Tube’s rise is seeing it use more and more electricity — and the report speculates that its energy consumption looks set to rise from around 0.1 per cent of 2010 global electricity levels to 1 per cent by 2013.
The report offers one extremely left-of-field solution to the problem: observing Moore’s law, it speculates that a one-petabyte drive capable of storing all the songs ever recorded could soon cost just $US100. Ship that to every user, it suggests, along with some remote server-based player required to access the content, and the planet’s resources won’t be drained as quickly. Convinced?
