Hydropower 101
Student Energy・3 minutes read
Hydropower is a crucial renewable energy source globally, providing cost-effective and dependable electricity while also assisting with flood control and water supply. However, environmental concerns regarding large dams include habitat disruption and greenhouse gas emissions, particularly from methane production in flooded areas.
Insights
- Hydropower, through dams and run-of-river hydro plants, efficiently harnesses flowing water to generate electricity, with the Hoover Dam exemplifying its immense capacity to power millions of people.
- Despite its advantages in cost-effectiveness and reliability, hydropower's environmental impact, including habitat disruption and methane emissions from flooded areas, raises concerns about its sustainability and long-term consequences.

Hydropower: Renewable Energy from Flowing Water
- Hydropower, also known as hydroelectricity, converts energy from flowing water into electricity, utilizing turbines and generators. There are two main types of hydroelectricity production: dams, which use potential energy from dammed water, and run of river hydro, which diverts natural water flow through turbines. Various sizes of hydro plants exist, with the Hoover Dam in the US generating a massive 2074 megawatts, serving 1.3 million people.
- Hydropower is a significant renewable energy source globally, offering cost-competitive and reliable electricity. It can be used as base load power and aids in flood control and water supply. However, concerns include environmental impacts from large dams, such as habitat disruption and greenhouse gas emissions during construction and decay of plant matter in flooded areas, leading to methane production.
