Welcome to our weekly newsletter focusing on environmental trends and solutions driving us towards a more sustainable future. Hi, I’m Alexandra. We stumbled upon a concerning issue involving eels dying in large numbers at hydro dams. It made us reflect on the lack of attention compared to other wildlife conservation efforts. These eels deserve safe passage through their habitats. Let’s explore a technology solution addressing this challenge.
This week’s highlights are as follows:

Every year, endangered American eels undertake a perilous journey down the St. Lawrence River towards their breeding grounds in the Sargasso Sea. Unfortunately, many perish due to turbine blade collisions at hydroelectric dams along the river, contributing to a drastic 99% decline in the local eel population since the 1970s.
Natel Energy, a California-based startup specializing in fish-friendly turbine technology, has developed a turbine runner aimed at preventing these fatalities without compromising power generation efficiency. This innovative design is a breakthrough as it demonstrates that safeguarding fish does not have to hamper power production or incur substantial costs.
American eels play a vital role in Canada’s ecosystem, with their migration downstream being crucial for the species’ overall survival. Despite being historically abundant in Lake Ontario, overfishing, habitat destruction, and hydroelectric dams have led to a significant decline in their numbers. Efforts to protect eels include banning commercial fishing in Ontario and implementing programs to bypass hydro plants.
Natel’s “FishSafe” turbine design features enhanced blade shapes and minimized gaps, reducing the likelihood of fish injuries. Computer simulations suggest a substantial increase in eel survival rates with this new design, offering hope for the species’ recovery. Moreover, the design’s efficiency matches existing turbines and can be seamlessly integrated into most systems without costly overhauls.
Natel Energy is collaborating with Canadian firms and has successfully tested its technology in France, showcasing its potential to revolutionize eel conservation efforts. The company envisions its innovation as a game-changer for the American eel population, emphasizing the importance of balancing ecological preservation with energy production.
Stay tuned for our next issue for more insightful updates on environmental breakthroughs and challenges. Your feedback and contributions are always welcome. Let’s continue working towards a greener and more sustainable world together.
