  7. 7. Typical Steam Plant Water Consumption Nuclear 0.83 gallons per KWH Coal, oil or gas 0.78 gallons per KWH Combined cycle 0.22 gallons per KWH
  8. 8. Georgia Power’s Fleet Consumption 0.6 gallons per KWH 23 gallons per day per household
  9. 9. Hydropower7 % of Georgia Power’s capacityIn Georgia, evaporation from lake surface is comparable to evapo-transpiration from vegetation that was inundated.Lakes also provide drinking water, recreation and for USACE, flood control and navigation supportGeorgia Power considers hydropower to be non- consumptive of water
