A new study from researchers at Lawrence Berkley National Laboratory and Northwestern University has found that streaming videos is more environmentally friendly than watching them on a DVD.
Explains U.S. News, “One reason is that DVD players tend to be older and less efficient than other devices, yet the biggest factor by far was the emissions generated from driving to and from a local video store or retailer. One hour of streaming video required about 7.9 megajoules of energy in 2011, the study found, compared to as much as 12 megajoules for DVDs. Similarly, online video emitted 0.4 kg of carbon dioxide, compared to 0.71 kg for DVDs.”
