Hehe, don't worry too much ~ The exhaust hood is generally around 60W to 300W, and the power is different because of different gears. Let's say the small exhaust fan is 60W. I think it's about 60W at most. 100 watt bulb point 10 hour is one degree of electricity, so it takes about 3 degrees of electricity to turn on a 60 watt bulb for 45 hours = 1 degree = 1000 watt/hour.

At present, the electricity consumption of residents is about 50 cents, and you spend about 1.5 yuan! So don't worry too much
