Powering A Generation: Generating Electricity
When demand rises, some of this water is channeled through a hydro-turbine to generate electricity. Since "peak-load" generating units (used to meet temporary demand surges), are generally more expensive to run than "base-load" units (which run most of the time), pumped-storage is one way to boost system efficiency.

How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Guide to Small Wind Energy Systems
The key feature of a small wind energy system is the wind turbine. The turbine uses the energy of motion (ki-netic energy) from the wind to turn a shaft, thus making mechanical energy. This shaft is attached to a generator. The resulting spin within the genera-tor makes electricity. A wind turbine thus operates the opposite way of a fan.
Renewable Energy | Department of Energy
In 2022, annual U.S. renewable energy generation surpassed coal for the first time in history. By 2025, domestic solar energy generation is expected to increase by 75%, and wind by 11%.

How a Nuclear Reactor Works
In most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission.
