Managing energy usage

We all know the entirety of europe is in an energy crisis, I have done a lot to reduce my energy needs from buying an air conditioner when before I used a space heater (I wanted to do that eventually anyway) to switching all light bulbs to new LEDs to turning off my PC or TV when I am leaving the room, things that were really easy but I didn't used to do because I was lazy and felt there was no need. So far I haven't had a huge power bill, but even with the cuts I've done it still is a little more than other years.
