This is a list of countries by total primary energy consumption and production.. 1 quadrillion BTU = 293 TW·h = 1.055 EJ 1 quadrillion BTU/yr = 1.055 EJ/yr = 293 TW·h/yr = 33.433 GW. The numbers below are for the total energy consumption or production in a whole year, so should be multiplied by 33.433 to get the average value in GW in that year.. List
