Last June 2 and 3 I was attending the Barcelona Global Energy Challenges conference that was held in Barcelona. It was the sixth edition of a forum co-organized by the  MIT Industrial Liason Program (MITILP), the Institute for the Energy Research of Catalonia (IREC) and the b_TEC foundation (b_TEC). In view of the current energy paradigm shift, representatives from the key institutions leading changes in technology and energy will answer questions like: What are the technological challenges facing top research centers and universities? How will the energy future unfold? What will the most successful options be? What areas will be the focus of energy innovation?
