The electricity you don't spend is electricity you don't need to produce. We don't really need electricity, we need to do useful stuff with it. Doing laundry with electricity is useful, as is having a computer network. Are massive glowing screens in the middle of the night useful? That would be a very long discussion, but I say no because any local usefulness is outweighed by their negative impact overall.

Saving electricity is just as useful as adding new capacity, and it's faster, cheaper and easier. As a comparison, the US spends about twice as much electricity as Germany per capita [1].
