How Hydroelectric Power Can Combat Climate Change


Climate change is a serious global threat, and it is affecting the world in many ways. It is causing rising sea levels, melting glaciers, severe droughts, and extreme weather events such as hurricanes and floods. The use of fossil fuels is one of the primary causes of climate change, and this is why it is essential to find alternative sources of energy. In this article, we will discuss how hydroelectric power can combat climate change.

What is Hydroelectric Power?

Hydroelectric power comes from the energy of falling water. It is produced by the kinetic energy of flowing water, which is transformed into electrical energy. The process of generating hydroelectric power involves building a dam on a river to create a reservoir. The water stored in the reservoir is then released through turbines to generate electricity.

The Benefits of Hydroelectric Power

One of the primary benefits of hydroelectric power is that it is a renewable energy source. It does not require fossil fuels, and it does not produce greenhouse gas emissions, which are the primary drivers of climate change. Hydroelectric power plants also have a long lifespan with low operating costs, making it a cost-effective way to generate electricity.

Hydroelectric Power and Climate Change

Hydroelectric power can play a significant role in reducing greenhouse gas emissions and combating climate change. According to the International Energy Agency, hydropower is currently the largest source of renewable energy and accounts for approximately 16% of the world’s electricity generation.

Hydroelectric power can help reduce carbon emissions in several ways:

1. Replacing Fossil Fuels

Hydroelectric power replaces the need for fossil fuels, such as coal and oil, which are the primary culprits of climate change. By using hydroelectric power, countries can significantly reduce their greenhouse gas emissions and cut down on their reliance on non-renewable resources.

2. Lowering Emission Intensity

Hydroelectric power also has a lower emission intensity than fossil fuels. According to the Intergovernmental Panel on Climate Change, hydroelectric power generates only 24 grams of carbon dioxide equivalent per kilowatt-hour, compared to 820 grams for coal-fired power plants.

3. Storage System for Renewables

Hydroelectric power can serve as a storage system for other renewable energy sources that are intermittent, such as solar and wind power. During periods of excess electricity from these sources, the excess energy can be used to pump water into a reservoir. When this stored water is released through turbines, it can generate power during periods when solar and wind energy are not available.


Overall, hydroelectric power can be a significant player in the fight against climate change. It provides a renewable source of energy that can replace fossil fuels and reduce greenhouse gas emissions. Hydroelectric power also has the potential to store excess energy from other renewable sources and provide a reliable source of electricity. As the world looks for more sustainable forms of energy, hydroelectric power will undoubtedly play a critical role in the transition to a clean energy future.
