Hydrology and Hydroelectric: The hydrological cycle is the circulation of water on our planet,
the most fundamental part of our climate and ecosystems. It provides an extensive renewable energy
resource, however hydroelectric megaprojects work against the timing of the hydrological cycle,
storing spring run-off in reserviors until winter, when electricity demands increase.
Our electricity demands have direct implications on sea ice ecosystems, thousands of miles away,
affecting people, animals, ocean currents and seasonality (Learn More).Additionally, freshwater
entering the North Atlantic is a major driver of ocean circulation and global climate. Worldwide,
over 50% of acessible freshwater is behind dams. We are changing the heart beat of our planet with
little regard for the consequences.
Solutions: The current approach to hydroelectricity involves massive infrastructure, diverting rivers and storing water as potential energy behind dams. River flow is based on electricity demands. Capturing energy in phase with the hydrological cycle could be achieved by storing and distributing it in new ways. For example, the east coast of North America has major energy demands for electricity and shipping that do coincide with the hydrological cycle. By storing energy in other forms besides water behind the dam, Hydroelectric projects could mitigate impacts on the hydrological cycle and at the same time provide the capacity for shipping companies transition to cleaner energy sources. Also, many small communities in direct proximity to hydroelectric developments still rely on diesel fuel to generate electricity. Our distribution models for both energy and shipping need to be coordinated to make sense first and foremost locally, before they can be sustainable at large scales. Our ability to adapt to changing economies and environments will depend on it. Hydroelectricity projects that work with the seasons of the hydrological cycle, could be a major part of solutions to our many global energy challenges.
Our Role: The society facilitates interdisciplinary collaboration and conducts active research on the cumulative effects of dams on the marine environment, and energy managaement, distribution and storage strategies that can work with the seasons of the hydrological cycle and minimize impacts on ocean currents, sea ice ecosystems and Inuit.
