In recent news, researchers have been studying the idea of installing solar panels over the top of canal systems. In short, this can help reduce evaporation of water, help plant growth and be used as a space for renewable energy. An article published in the Nature journal also argued that the idea of installing solar panels over canal systems outweigh the ecological and financial alternatives of installing them elsewhere; concluding that this method produces 20%-50% more solar power than conventional methods.
