![]() The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse. ![]() Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. At the end of its passage down the pipes, the falling water causes turbines to rotate. In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation the difference in these two elevations is known as the head. In the early 21st century, hydroelectric power was the most widely utilized form of renewable energy in 2019 it accounted for more than 18 percent of the world’s total power generation capacity. Hydroelectric power, also called hydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
