Most power generation consumes water, whether to cool steam in thermoelectric plants or power turbines for hydropower. And the global demand for both water and electricity will continue to increase substantially in the coming decades. Although growth is generally a good thing for the economy, it challenges nations—particularly ones that are water-stressed—to better manage their limited water resources and invest in the right energy systems.
Power generation from solar photovoltaic (PV) and wind is clean and requires zero or little water use. These renewable forms of energy can help countries meet their increased demand for electricity without adding carbon emissions or consuming water. This could be particularly beneficial in countries where growing populations, farms and industries are already competing for scant water supplies. For example, a recent WRI analysis shows that India could reduce its water consumption intensity by more than 25 percent just by achieving its renewable energy targets.
Leveraging WRI’s Resource Watch, a new global data platform, we overlaid map-based data sets to identify countries that are water-stressed and have high solar and wind energy potential. These countries are places where solar PV and wind technologies are more likely to be financially attractive and provide water savings that would benefit the public greatly.
