A water turbine, with the Kaplan, Pelton, and Francis turbines being the most common ones, is a large rotary machine that works to convert kinetic and potential energy into hydroelectricity. These modern equivalents of the water wheel have been used for over 135 years for industrial power generat...Read more »

Hydropower is by far the largest renewable worldwide, producing over twice as much energy as wind, and over four times as much as solar. And pumping water up a hill, aka “pumped storage hydropower”, comprises well over 90% of the world’s total energy storage capacity. But in spite of hydropower’...Read more »

Both hydropower and thermal power must have an exciter. The exciter is generally connected to the same large shaft as the generator. When the large shaft rotates under the drive of the prime mover, it simultaneously drives the generator and the exciter to rotate. The exciter is a DC generator tha...Read more »

Hydropower is to convert the water energy of natural rivers into electricity for people to use. There are various sources of energy used in power generation, such as solar energy, water power in rivers, and wind power generated by air flow. The cost of hydropower generation using hydropower is ch...Read more »
