If you plan to upgrade your entertainment system after remodeling your home, be sure to choose EPA Energy Star cable box, modem, TV monitors and routers. Each of these units saves 30 watts or more than non Energy Star models.
Streaming over internet is getting more and more popular. One of the advantages of streaming is that the material can be delivered to many different devices through many different networking arrangements. However, these different delivery methods are not the same in terms of energy consumption. Streaming through game consoles use the most energy, likely 10 times more than streaming to laptops or tablets.
While you enjoy staying home to watch your favorite shows/movies, you can easily save energy by using Energy Star equipment.
When in doubt, check the Energy Star for the most up-to-date information about the devices you plan to use.
