Energy Streetfight, consumption virus & the four dimensions of sustainability (TEDxBerlin))

The presentation we held at TEDxBerlin in November 2011 starts off with a description of Energy Streetfight, a playful approach to reduce domestic energy consumption which we set up in Berlin in 2011 [1], [2]. In the remainder of the presentation we try to outline why and how

• an experimental attitude,
• an entrepreneurial mindset which fosters activity (in the example of Energy Streetfight: playful activity) and
• an understanding of sustainability and value creation which goes beyond the resource view and takes into account four different dimensions (scientific, systemic, cultural, psychological)

can be used to think up and create better systems: Sustainable Value Systems.
Can you see how this approach could help you to think about your venture? If so, how? If no - what would need to be improved? What are the questions that remain?
