If you are in the energy business then “CERAWeek,” a convention in Houston put on by the energy consulting firm Cambridge Energy Research Associates (CERA), was the place to be last week. Attending this “world renowned event” were some 1,600 “CEOs, sheiks, professors, analysts and energy decision makers,” who paid up to $5,500 to listen to 120 distinguished speakers pontificate on the future of the world’s energy supplies.
