This wiki advocates for [[reduce energy demand|decreased energy consumption]] in rich ("developed") countries. But also, poorer countries might need to ''increase'' their energy use. So for lack of more detailed data, the status-quo based "quick estimate" provides a "middle of the road" sense of scale for the amount of renewables that might be needed to reach [[net zero]] carbon emissions. | This wiki advocates for [[reduce energy demand|decreased energy consumption]] in rich ("developed") countries.
