At the moment, very little.
65w lights and I only run them for 5 hours a day. WC water for garden water.
But I'm sure it is outdone by the complete wet/dry, canister, 300w heater, and 10 gallon hospital tank with heater, HoB, and sponge filter.
Something doesn't sound "green" about 2 power strips so full there are outlet splitters on some outlets.
