Finding New Urban Geothermal Energy Heating Sources from Satellites


Linking Surface Urban Heat Islands with Groundwater Temperatures (Abstract, Susanne A. Benz, Peter Bayer, Frank M. Goettsche, Folke S. Olesen, and Philipp Blum, Environ. Sci. Technol., Nov. 23, 2015)
Also discussed here: Satellites find sustainable energy in cities (Science Daily, Dec. 18, 2015)
Today we review research that bridges the well studied, (above ground) urban heat island with the urban ground water using satellite-derived temperatures and urban characteristics, such as population density and the number of cellars found in many older cities. This approach tested in Germany, found a spatial correlation of up to 80 % between the above and below ground heat islands and offers the potential of maximizing the potential for using warmer ground water in cities as an energy source for different cities over a large area. This in turn would help to ease the use of carbon fuels otherwise needed to warm urban buildings in winter.
