When it comes to renewable energy, hydroelectric power is often touted as the gold standard. It’s clean, it’s green, and it’s virtually limitless. But as it turns out, the world’s most widely used source of renewable energy has a dirty secret. Behind its sparkling facade, hydroelectric power is actually a major environmental menace, threatening the very ecosystems it’s supposed to protect.

One of the main problems with hydroelectric power is its impact on aquatic ecosystems. The construction of dams and reservoirs disrupts the natural flow of rivers, causing changes in water temperature and chemistry that can be catastrophic for native fish and other aquatic species. In fact, the construction of the Three Gorges Dam in China has been linked to the decline of the Chinese sturgeon, an ancient species that’s been around since the time of the dinosaurs.
But that’s not all. Hydroelectric power also has a profound impact on the landscape itself. The creation of reservoirs and dams requires the flooding of vast areas of land, often displacing entire communities and destroying habitats. In the United States, for example, the construction of the Hoover Dam in the 1930s resulted in the flooding of over 250 square miles of land, displacing thousands of people and destroying countless acres of natural habitat.

And then there’s the issue of greenhouse gas emissions. While hydroelectric power is often touted as a carbon-free energy source, the production and transportation of the materials required to build hydroelectric dams and turbines actually result in significant greenhouse gas emissions. In fact, a study by the University of California found that the production of a single hydroelectric turbine can result in the release of over 30 tons of CO2 into the atmosphere.
So what’s the alternative? Clearly, hydroelectric power isn’t the panacea it’s often made out to be. But that doesn’t mean we have to give up on renewable energy altogether. In fact, there are plenty of other options that are just as effective – and far less destructive. Wind power, for example, is a rapidly growing industry that’s increasingly competitive with hydroelectric power in terms of cost. And then there’s solar power, which is becoming more efficient and affordable by the day.
Of course, there are still those who will argue that hydroelectric power is worth the risks. After all, it’s a reliable source of energy that’s been around for centuries. And in many parts of the world, it’s still the best option available. But the truth is, we don’t have to choose between hydroelectric power and environmental destruction. We can – and we must – do better. The future of our planet depends on it.
