10 Reasons Why Hydropower Isn’t a Climate Solution
From The Observatory
Hydropower, once seen as a renewable and climate-friendly energy source, is now known for its adverse impacts on the environment and local communities. Despite claims that it can help combat climate change, hydropower dams pose significant risks and contribute to greenhouse gas emissions. Here are ten reasons why hydropower is not a viable solution for addressing the climate crisis.
1. Vulnerability to Climate Change
Hydropower projects are vulnerable to the impacts of climate change, such as droughts and extreme weather events, which can disrupt energy generation and pose risks to downstream communities.
2. Methane Emissions
Dams produce significant amounts of methane, a potent greenhouse gas that contributes to global warming. The flooding of vegetation and organic matter in reservoirs leads to methane emissions, exacerbating climate change.
3. Flawed Climate Calculations
Efforts to expand hydropower capacity as a climate solution overlook the fact that dam construction and reservoir creation result in significant emissions. Building new dams can actually increase greenhouse gas emissions in the short term.
4. False Marketing as Sustainable
Hydropower projects are often marketed as sustainable, but they fail to meet sustainability standards. The claims made by industry groups do not align with scientific evidence.
5. Human Rights Violations
Large hydropower projects have serious human rights implications, displacing millions of people and violating the rights of Indigenous communities.
6. High Costs and Inefficiency
Hydropower projects are costly to build and maintain, often experiencing delays and cost overruns. The energy produced is often inaccessible or too expensive for local communities.
7. Impact on Free-Flowing Rivers
Dams disrupt free-flowing rivers, which provide vital ecosystem services, including carbon sequestration and water supply. Dams result in water loss through evaporation and fail to provide the same benefits as natural river systems.
8. Availability of Alternative Energy Sources
Clean and renewable energy sources like solar, wind, and geothermal power are increasingly cost-effective and competitive with hydropower. These alternatives offer sustainable energy solutions without the negative impacts of dams.
9. Biodiversity Loss
Hydropower dams contribute to the decline of freshwater species and the degradation of freshwater ecosystems. As the world faces a biodiversity crisis, expanding hydropower is incompatible with conservation efforts.
10. Addressing the Root Cause
To effectively tackle climate change, biodiversity loss, and other global challenges, we must address the root causes of these crises. Hydropower dams do not provide a holistic solution and can exacerbate existing problems.
Conclusion
Hydropower is not the solution to the climate crisis. It poses risks to the environment, local communities, and biodiversity while contributing to greenhouse gas emissions. To address climate change effectively, we must invest in sustainable and alternative energy sources that are cost-effective, environmentally friendly, and socially responsible.
