Basics
- The energy that is returned, after all the energy used to produce, as well as maintain (and eventually dissasemble/recycle etc) the device/system for it's entire Product Life Cycle
- One of the most important metrics in a LCA (Especially in power plants, or more likely in OSE's case smaller devices)
- Also an intresting way to see technology develop, Photovoltaic Panels were considered very low, or even negative, in the early days, but are now ~10x Net Energy Gain
