Guest Post from Dick Storm. America uses right at 100 Quadrillion BTUs of Primary energy each year. We have used about this amount for over 20 years. The entire world uses about 600 Quadrillion BTUs of total Primary energy. The energy systems to provide this indispensable primary energy are beyond huge. They are so large and complicated that it is difficult to describe in words. Let me attempt to demystify the immensity of the energy systems we depend on.
Simply encyclopedic, Dick. Thanks for your hard work and scholarship.
