With online video streaming platforms like Netflix and Amazon Prime gaining popularity, scientists analysing their impact on the environmental have some bad news. Climate experts reveal that the convenience of streaming videos online comes with a hefty environmental price tag. A half an hour show leads to emissions equivalent to 1.6 kilograms of carbon dioxide! That's equivalent to driving for about six kilometres. Digital videos come in very large file sizes and are getting bigger with each new generation of higher definition video. More data means more energy is needed to maintain a system that streams this video to your device.
