- The energy costs of operating the world’s largest oil fields can rise dramatically as extraction rates begin dropping, according to a study published in the journal Nature Climate Change. As extraction begins to ramp down, the net energy from the process can begin to fall rapidly, so that each unit of oil becomes more carbon intensive. [CleanTechnica]
