'Suchlike' obviously include the internet for example. We want power to do what we're doing now. As we don't necessarily need to be doing what we're doing now we don't really need the electricity to do so. Instead we want to do what we're doing now so we simply want the electricity to do so ... and loads more besides.

I'm off to read a book in bed now, which is something I want to do, not need to do, so I will be wanting loads* of electricity to it.

*but I have got an energy saving** bulb in the bedside light.

** The only energy saving bulb is a broken one!
