Hydroelectric - Hydroelectric Power

Renewable energy sources are becoming increasingly vital as the world seeks to reduce its carbon footprint. Solar and wind power are the most prominent, but geothermal and hydroelectric power also play crucial roles. Geothermal energy harnesses heat from beneath the Earth's surface, providing a steady and reliable power source, unlike solar and wind which are dependent on weather conditions. Hydroelectric power relies on flowing water, typically from dams, to turn turbines. While highly efficient, hydroelectric projects can have significant environmental impacts, such as altering river ecosystems and displacing communities. According to the passage, what are some characteristics of geothermal and hydroelectric power?
