How many monthly kilowatt hours, including hi-fi, do you use?

I’m proud to say my monthly kilowatt usage is approximately 400 kWh and rises to 450 or so in the summer with air conditioning. Each night use about 4 kwh for my audio gear which includes 30 tubes mostly in amplifiers. Yes this is the worst of my sins using a tube amplifier.

Curious if you know how much you use and if so how much is it?

I’m a big proponent of conserving electricity to help out the planet.
