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

light bill is really expensive here in Texas

i pay 400-500 every month and most of the time my  system is off since I travel a lot for work 

I average 1100 kWh per month but my out-of-pocket cost is less than $100.  I have a large solar panel array and a large geothermal heat pump with coils submerged in a pond.  Grid electricity is provided by a nuclear power station.  Oh, and my Gan1 amp uses next to nothing.  I did all that because it made good economic and audio sense, not to save the planet or signal my virtue.  In fact, I'm conservative and don't believe there is a climate crisis. 

I’m a misor for power usage. This is good if electric blackouts become more frequent.

My Pass XA25 manual says 240W at idle. 30 days would be about $30 if my math is right, I am getting older, and humble, so correct me if I'm wrong.

Don't know and don't care. Have more important things to worry about.

Oh brother....never heard of any one keeping track of energy usage for a hifi. The whole green thing is bogus and a political power grab. Another way for big brother to control you. I pay my electric bill, that's all That matters. Oh and I turn off lights in rooms not being used. Hard, I have kids.
