Night light is soft
Electric light switches are so easily turned on, and can easily be turned off. In some countries electricity is relatively cheap; we can ‘afford’ to light our houses up and turn night into day. The negative feedback that we must accept is climate change due to carbon emissions. The average daily electricity use for Australian households of 20 kW/hr could easily be reduced to less than 5 kW/hrs. - David Arnold. Photo by Oliver Holmgren
