Modern-day game consoles like the Xbox and PlayStation 4 can do more than just play games. In fact, many of them can stream movies, TV shows and internet video through the console to your TV. While convenient, it is also a disaster when it comes to energy efficiency. Streaming this way makes the console eat up 30 times more energy in comparison to watching programming on your TV. Instead, opt for on demand shows and internet-ready devices for the convenience without the waste of electricity.
