Hydro electric power plant
Hydroelectric power plants capture the kinetic energy of flowing water from a river or reservoir and convert it into electrical energy. These power plants are generally located in hilly areas where a dam can be constructed to form a reservoir. Water from the reservoir flows through penstocks and turbines, using the force of gravity and water pressure to turn the turbine blades. This kinetic energy is then converted into electrical energy by an attached generator. The electricity is stepped up in voltage by transformers and distributed via power lines to customers. Hydroelectric power is a renewable source of energy and provides the additional benefits of flood control, water storage, and irrigation.

Hydro Energy (P Corry)
Hydro energy works by building dams to trap water from sources like lakes and rivers. The water builds up behind the dam, creating pressure. When released through tunnels with turbines inside, the water's pressure turns the turbines to generate electricity. Hydro energy has zero emissions and low operating costs once dams are built, but dams are very expensive to construct and can impact local environments. It provides a more sustainable alternative to power stations that burn fossil fuels and release greenhouse gases, as seen when comparing a coal-powered station to a hydroelectric dam. The document recommends hydro energy as a better long-term energy source due to dwindling fossil fuel supplies and its lower environmental impact.
Hydro
Hydroelectric energy is generated by building dams that force moving water to turn machinery like turbines connected to generators. This converts the kinetic energy of the flowing water into electrical energy. While hydroelectricity is a renewable source that doesn't pollute, building large dams can be very expensive and damage wildlife habitats by flooding land. However, small-scale experiments show how kinetic energy from moving water can be used to light a bulb by powering a small turbine connected to a dynamo.

HYDRO POWER
Head
Water must fall from a higher elevation to a lower one to release its stored energy.
The difference between these elevations (the water levels in the forebay and the tailbay) is called head Dams:
three categories
high-head (800 or more feet)
medium-head (100 to 800 feet)
low-head (less than 100 feet)
Power is proportional to the product of head x flow
Hydroelectricity
Hydroelectricity is the production of electricity through the use of the gravitational force of falling or flowing water. It accounts for 16% of global electricity generation and is the most widely used renewable energy source. Hydroelectric power is produced in 150 countries, with China being the largest producer.

Hydropower
- 2. 2 Hydro Energy Hydro energy is simply energy that is taken from water and converted to electricity. Hydro energy can be obtained by using many methods of capture. The most common method of using energy from water is a hydroelectric dam, where water coming down through an area causes turbines to rotate and the energy is captured to run a generator. Power can also be generated from the energy of tidal forces or wave power, which uses the energy created by waves.
