Yes, I asked Claude and it estimated 10-50 kWh if you max out Max 5x subscription (which I have, and I use it about 30-40%).

Further estimation gave it's about like having another gaming PC, i.e. 100-300W when I am actually gaming.

I live quite low carbon intensity lifestyle, don't travel much, don't have a car or a family, so it's not really a big expense.
