Rechecked my usage, about 3100 KwHr per year
Gas water heater, forced air furnace, range, dryer
Electricity used to operate laundry, lights, countertop appliances (I use a Breville Smart Oven quite often because it's faster and more efficient for small jobs). 50" LED tv, rarely used.
Energy hogs:
1. 100 gallon/380 liter salt water aquarium. Fish and live rock but no live coral, which requires much more lighting. Four pumps, three are 20W and one is 12W. LED light fixture 72W. Heater 150W but basically in use only 3-4 months of the year, keeps tank at 75 F. Not counting heater, tank uses 140W when lights are on, 80W when lights are off, and add 150W when heater is engaged. I should note that three of the four pumps are submerged and add heat to the water, lessening the load on the heater.
2. Router and modem, about 20W total and always on because I "share" my WiFi with my neighbor. Before I began to share with him, I would turn it off when I was not at home.
I figure the aquarium is about 30% of my electricity use. Coral tanks require way more lighting and probably burn 300-500W when the lights are on.
