Adaptation Can Compound Climate Change Impacts on Energy and Water

As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California’s energy goes toward water-related activities, while more than a tenth of the state’s electricity comes from hydropower. As society tries to adapt to one challenge, it needs to ensure it doesn’t worsen the other.
To this end, researchers from UC Santa Barbara, Lawrence Berkeley National Laboratory and UC Berkeley have developed a framework to evaluate how different climate adaptations may impact this water-energy nexus. Their research appears in the open access journal Environmental Research Letters.
By doing so, we illustrate often-overlooked tradeoffs and synergies in adapting to climate change, she continued.
By understanding the links between these two challenges, future impact on climate change could be minimized.
Co-author of the paper and Berkeley Lab scientist Andrew Jones said If we focus on adapting the water system by using big transfers of water across basins, or by using energy-intensive desalination, that’s just going to make the electricity problem much more difficult. If, on the other hand, we adapt the water system by conserving water, it’s actually a win-win situation because you’re also reducing the energy required for water.
