Peter Tertzakian is a career-long analyst of the energy sector, and an avid collector of antiquities from the sector. At his TEDxCalgary talk, he takes us through our energy predicament of the next five to ten years by drawing parallels to the introduction of the convex lens and the whale oil lantern and the challenges this posed for the candle-making industry of the time.Learn more about Peter at http://peter-tertzakian.tedxcalgary.ca

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
