Vesivoimala

Vesivoimala is a Finnish term that translates to hydropower plant or hydroelectric power station. It refers to facilities that generate electricity by harnessing the energy of moving water. These plants typically utilize dams to create a reservoir, controlling the flow of water. When electricity is needed, water is released from the reservoir and channeled through turbines. The force of the water spins the turbines, which are connected to generators that produce electrical energy.

The principles behind vesivoimala are centuries old, with early forms of watermills used for mechanical power. Modern vesivoimala, however, are sophisticated engineering feats designed for large-scale electricity production. They are a significant source of renewable energy in countries with abundant water resources, like Finland. The environmental impact of vesivoimala can vary. While they produce clean energy without direct greenhouse gas emissions, the construction of dams can alter river ecosystems, affect fish migration, and inundate land. The efficiency and capacity of a vesivoimala depend on factors such as the height of the dam (head) and the volume of water flowing through the turbines (flow).
