The pros and cons of hydropower

Hydropower is a clean and renewable energy source that pairs well with other renewable energy technologies. It is also produced domestically and can be used for irrigation. However, hydropower installations adversely impact the physical environment around them, are often expensive to build, and there are limited places suitable for reservoirs and hydroelectric plants.

The Pros of Hydropower

• Hydropower is a clean and renewable energy source. Unlike traditional fossil fuel energy sources, using water to generate electricity doesn’t release harmful pollutants into the air or water.
• Hydropower pairs well with other renewable energy technologies. The majority of hydroelectric plants are storage or pumped storage facilities that store large amounts of water in reservoirs. This means that hydropower can be a stable source of supporting energy for more intermittent energy sources like wind and solar.
• Hydropower is produced domestically. Unlike fossil fuels and most available solar panels, hydropower is entirely produced in the United States. This has benefits for job creation and means there is no need to rely on imports from other countries.
• Hydropower can be used for irrigation. Hydropower reservoirs can be used as a clean and reliable source of freshwater in areas where rain is scarce and droughts are common.
• Hydropower is inexpensive in the long run. While there are high upfront costs associated with hydropower, it is one of the most inexpensive forms of renewable energy over time. Once the necessary infrastructure is constructed, there is less maintenance required for upkeep than other forms of energy.

The Cons of Hydropower

• Hydropower installations adversely impact the physical environment around them. Most hydropower plants require the construction of a dam, which results in the destruction and fragmentation of the surrounding habitats. This can lead to the flooding of large areas within a river valley and the displacement of both humans and animals.
