Fire: Predicting how much energy tomorrow’s world will need depends on assumptions about, for instance, how many of the roughly 1.2 billion people who do not have electricity will actually get it, and how that electricity will be provided (solar power, nuclear power, natural gas, wind, coal). Still, the main thrust of every attempt to estimate future requirements that I am aware of is that the human enterprise will require more energy—probably quite a lot more. What to do about it depends on whether you ask Borlaugians or Vogtians.
