The Water-Energy Nexus: Powering Public Transportation
Wastewater treatment holds enormous potential for generating renewable energy, mainly through biogas production. By converting organic material in wastewater into biogas, cities can create an eco-friendly fuel that powers public transportation, heating, and electricity. This process reduces waste, decreases dependence on fossil fuels, and lowers greenhouse gas emissions.
Public transportation systems are increasingly turning to biogas to shrink their carbon footprints. Integrating wastewater treatment with energy production creates a sustainable energy loop that powers transit systems and essential services. Biogas derived from wastewater is crucial in transitioning from fossil fuels to greener, more resilient transit solutions.

Learn how Stockholm’s Henriksdal and Bromma plants generate millions of cubic meters of biogas annually, powering public buses and cutting carbon emissions.
Renewable Energy Opportunities for Wastewater Treatment Plants
Wastewater treatment plants are emerging as key players in the renewable energy landscape. By leveraging solar, hydro, and biogas resources, these facilities can power their operations sustainably and contribute excess energy to the grid. This approach reduces operational costs while advancing net-zero emission goals in the water sector.
With innovations like solar farms and mini-hydro stations, wastewater treatment plants are transforming into energy hubs. These facilities reduce emissions while generating clean electricity by harnessing renewable energy sources, like solar, hydro, and waste-to-energy systems. The transition to energy self-sufficiency is vital for creating sustainable, low-carbon urban environments.
