Sometimes new green jargon is a lot for the newly green to feel comfortable with. Net zero is a term with many definitions but all run in a similar vein. In a nutshell, net zero means no overall energy consumption or “net zero” and zero annual carbon emissions. In other words, even though some energy is used, the energy is from renewable energy sources and no energy is purchased from the grid or external energy producers because the home produces as much energy as it consumes.
