From Alpha 2 Omega Episode 41: This weeks our guest is Dr Marco Raugei. We discuss his work on renewable energy, in particular his work on the current state of Photovoltaic or PV systems. We learn about the key differences between Energy Returned on Energy Invested and efficiency, bootstrapping fossil fuels to build a renewable future, re-organisation of our current economic system, and renewable energy’s storage problems.

Read Marco’s essay: If we have to use fossil fuels to manufacture renewable plants, doesn’t it mean that renewables are useless?
