Solar above, fish below: Double-decker farms could rival US power use
A new study suggests that covering aquaculture ponds with floating solar panels could generate enough electricity to rival the United States' annual power use, significantly reducing carbon emissions. The approach, called aquavoltaics, combines solar energy production with fish farming. The study highlights the potential of this dual-use system to support sustainable energy and food production globally.
Covering aquaculture ponds with floating solar panels could generate 4,100 terawatt-hours of electricity annually, enough to offset a large portion of the industry's carbon emissions. The study estimates that this could avoid 2.5 billion tons of CO2 emissions each year.
This approach offers a way to produce clean energy and food simultaneously, helping to reduce reliance on fossil fuels and support sustainable development. It could be especially beneficial in regions with high aquaculture activity and limited land for solar farms.
The idea shows how innovative land use can address multiple global challenges, offering a practical and scalable solution that benefits both the environment and communities. It reflects a constructive approach to balancing energy and food needs.
