Renewable Energy in the Water, Food and Energy Nexus

Abstract

Renewable energy technologies can address trade-offs between water, energy and food, bringing substantial benefits in all three key sectors. This report from the International Renewable Energy Agency (IRENA) looks at how adopting renewables can ease trade-offs by providing less resource-intensive energy services compared to conventional energy technologies. An energy system with substantial shares of renewable energy would be less water-intensive than one dependent on fossil fuels. Renewable energy technologies can boost water security by improving accessibility, affordability and safety. Integrating renewable energy in the agrifood supply chain helps to rein in cost volatility, bolster energy security, reduce greenhouse gas emissions and contribute to long-term food sustainability. Modern bioenergy – sustainably and efficiently managed – could play an important role in these ongoing transformations.
