Illustration of challenges and opportunities of the energy transition through the lenses of an ex-fossil fuel business developer. Where dependency of our energy supply on hydrocarbons will remain large for years to come, the value of experience in the fossil driven world in this transition era, is underlined in this lecture. Communication driven through specific languages, experience for large capex intensive projects and the politics beyond energy security are some of the direct obvious competencies that will surface. The lecture will enjoy some examples of the winning technology/economics tandem: Concentrated Solar Power, wind, Photo Voltaic and biomass. There is no way back, but how fast will the transition go and how smooth will the road be?
