Do you grow any plants in your home? An average family home will have around a tenth of that energy consumption if you turn on all the lights. 200 watt tops. That is 25 LED bulbs of 8 watt.
I realized I did accidentally almost double my final number, so 500-1000W would be more accurate for the way this condo was built (depending on which extra lamps we are including—does every understair closet light count or just the main rooms, at the low end estimate)
