Integration of deep geothermal energy and woody biomass conversion pathways in urban systems

François Maréchal, Léda Gerber, Emanuela Peduzzi, Stefano Moret

Urban systems account for about two-thirds of global primary energy consumption and energy-related greenhouse gas emissions, with a projected increasing trend. Deep geothermal energy and woody biomass can be used for the production of heat, electricity and ...
