From the BBC comes this interesting article. Link here.
For those who don’t wish to read, here’s the short answer: “Once vinyl or a CD is purchased, it can be played over and over again, the only carbon cost coming from running the player. However, if we listen to our streamed music using a hi-fi sound system it’s estimated to use 107 kilowatt hours of electricity a year, costing about £15.00 to run. A CD player uses 34.7 kilowatt hours a year and costs £5 to run.”
So, friends, think about that as you stream your files! Of course, one needs to factor in the energy and potential environmental effects of vinyl and CD production in the final analysis.
