Welcome to our weekly newsletter showcasing environmental trends and solutions driving us towards a more sustainable world.
Hi, I’m Alexandra. We stumbled upon a concerning story about eels perishing in large numbers at hydro dams, prompting us to reflect on the lack of attention compared to other wildlife incidents. Eels deserve safe passage through waterways. Discover a tech solution addressing this issue.
This week’s highlights include:
– Eels facing mortality in hydro dam turbines. Innovative design could revolutionize the situation.
– The Big Picture: Understanding the functionality of heat pumps.
– Unveiling the mystery behind an airship hovering over a central Alberta town.
Each year, a significant population of endangered American eels migrates down the St. Lawrence River towards their breeding grounds in the Sargasso Sea. Tragically, many fall victim to the turbine blades of hydroelectric dams along the river, contributing to a drastic 99% decline in the eel population since the 1970s.
Natel Energy, a California-based startup specializing in fish-friendly turbines, has developed a new turbine runner to prevent these fatalities without compromising power generation efficiency. This breakthrough eliminates the historical belief that protecting fish would lead to power loss or increased costs.
American eels are vital to Canada’s biodiversity, being the only true catadromous species in the country. They play a crucial role in the ecosystem and hold cultural significance for Indigenous communities along water bodies like Lake Ontario, St. Lawrence, and Ottawa rivers.
With declining eel numbers due to various factors like overfishing, habitat loss, and hydro dams, conservation efforts have intensified. Natel’s “FishSafe” turbine design offers a promising solution, enhancing eel survival rates while maintaining operational efficiency.
The new design, featuring curved blades and advanced safety features, can significantly improve eel survival rates passing through hydro dams. Natel Energy aims to collaborate with hydro dam operators globally to implement these innovative solutions and safeguard aquatic biodiversity.
Let’s protect our eels and pave the way for a brighter future for these remarkable creatures.
