Can anyone tell me the golden idea of saving energy and reducing consumption in hotels? It's urgent ! !

Central air conditioners can save energy by 20-35% by replacing more efficient refrigerants. At least 18 hours of lighting is replaced by LED lights every day, which can save energy by more than 50%. If 2 yuan is electrified once according to the commercial electricity consumption, the monthly electricity consumption of the hotel is 160000 kWh, and your monthly electricity bill is 320000 kWh. By adopting the above energy-saving scheme, the electricity bill in January will be saved by about 25%, that is, the electricity bill will be saved by 8W per month and 96W per year.
