*Emergency generator fuel consumption varies based on size and load. A 1000-2000W generator may use 0.25-0.5 gallons/hour, while a 22,000W generator can consume 2-3 gallons/hour at half load. These estimates help in planning fuel needs during power outages, but actual consumption depends on the generator’s make, model, and specific conditions. Always refer to the manufacturer’s specifications for accuracy.*
