![]() ![]() This balance is highly skewed for fossil fuels (Hubbert 1956 Ward et al. Non-renewables are energy and matter forms typified by a marked gap between the rate of resource uptake and the time required by natural cycles to regenerate the resource (Tiezzi 2003). The use of non-renewable resources characterizes our production processes, transportation, and consumption. These observations of the earth at night result from the direct or indirect consumption of non-renewable energy resources. These composites of night-time satellite imagery enable the visualization of a geography of human activity (Elvidge et al. ![]() The spatial distribution and intensity of nocturnal lighting can be mapped globally. The intensity of nocturnal lighting ranges from very high in urban areas to very dim or completely dark in rural and wilderness settings. Photographs and satellite images have documented this extensively (Elvidge et al. Modern human activity lights up the surface of the earth at night.
