New perspectives on green energy production expansion for Water-Energy-Food nexus synergies

There is now a prospect for complementary production of renewable energy to stimulate water, energy, and food nexus synergies – read the new paper by METABOLIC.

The METABOLIC project funded under the Sustainable Urbanisation Global Initiative (SUGI)/Food-Water-Energy Nexus has published a new paper that opens up new perspectives on green energy production expansion while flourishing Water-Energy-Food nexus synergies, in support of policy-makers with feasible schemes on floating photovoltaic deployment.

Abstract extract
Hybrid hydropower and floating photovoltaic power generation has far-reaching effects on the intertwined water, energy, and food (WEF) nexus, but the complementary operation is fundamentally challenging especially under high uncertainties of hydro-meteorological conditions. We proposed an artificial intelligence-based WEF system-overarching solution driven by hybrid hydro-floating photovoltaic power generation for promoting nexus synergies. The results demonstrated that the proposed optimization model could significantly improve synergistic benefits of the WFE nexus by reaching 13%, 13.3% and 15.1% in water storage, food production and hydro-floating photovoltaic power output, respectively. New niches are exploited for floating photovoltaic deployment and give rise to impact mitigation concerning hydro-meteorological uncertainties on WFE nexus management.


  • Propose a multi-objective method to raise mutual benefits of water-food-energy nexus.
  • Floating photovoltaic deployment on ponds drives up renewable energy output.
  • Hybrid hydro-floating photovoltaic power generation raises energy efficiency.
  • Energy-driven solutions improve water-food-energy nexus management.
