Good point. All these streaming sites are inefficient by design. Even without the DRM the Server will have to encode the video and audio (or possibly even transcode them if the client only supports certain formats) before sending them to the client. And this happens on the fly every time anyone watches anything. If those streaming sites were all just a fancy looking file server that make you download the source video files directly (kind of like GOG does with video games) then that would greatly reduce energy consumption long-term.
