At the plant level, water flows through a pipe—also known as a penstock—and then spins the blades in a turbine, which, in turn, spins a generator that ultimately produces electricity. Most conventional hydroelectric facilities operate this way, including run-of-the-river systems and pumped storage systems.... view details ›
Hydrogen can also serve as fuel for internal combustion engines. However, unlike FCEVs, these produce tailpipe emissions and are less efficient. Learn more about fuel cells. The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 kilograms) of gasoline.... read more ›

One significant reason why water is considered renewable resources is that when it rains, the water bodies get replenished. Rain is usually in liquid form or droplets which are formed as a result of condensation in the atmospheric water vapors. Then, the droplets grow heavy and fall under gravity as rain.... see details ›
The velocity of rain is limited by air resistance and typically has a maximum of around 8 m/s . Doing the calculation, the amount of kinetic energy falling on a 185 m2 roof is about 59.2 kJ (0.016 kWh) per cm of rain. This is only about 1.6 kWh of energy per year in an area that receives a meter of rain per year.... see more ›
Energy is possessed by rain drops is kinetic energy when they just fall on the ground after falling kinetic energy of the rain drop is converted into heat and sound energy.... view details ›
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.... see details ›
