In most Western homes, lighting is a tiny part of electricity consumption, and even more so now that LED lights are becoming prevalent. Heating, air conditioning, refrigerators, washing machines, tumble dryers, dishwashers, hobs or ovens are typically responsible for more electricity consumption. Personally, since I don't have air conditioning, only use heating ~3 months a year (I live in a very mild climate) and almost don't use the tumble dryer, I would have a very hard time cutting my consumption by two thirds. Maybe not using the dishwasher, washing clothes less (or by hand) and cooking less, but probably it wouldn't be enough.
