Hydroelectric power works by storing water in reservoirs behind dams. The water is then released through penstocks where it spins turbines connected to generators, producing electricity. The electricity is carried by power lines to homes and businesses. Generators convert the mechanical energy of the spinning turbines into electrical energy using electromagnets and conductors. Pumped storage methods pump water to reservoirs during low demand to be released through turbines during high demand periods.

T&S_ppt final for Hydro Electric Power Plant Presentation
Hydropower harnesses the kinetic energy of flowing water to generate electricity. The amount of electricity generated depends on the water flow rate and head (drop height). Greater flow and head produce more power. Humans first used waterwheels to harness water's kinetic energy for tasks like grinding grains. Modern hydropower plants use turbines connected to generators to convert the kinetic energy of falling water into electric power transmitted via power lines. The world's theoretical and technical hydropower potential is large, but only a fraction has been developed so far, with opportunities existing worldwide.

Hydropower produces 24% of the world's electricity by harnessing the kinetic and potential energy of flowing water. Water is captured behind dams and directed through pipes called penstocks to spin turbines connected to generators. The three main types of hydropower plants are diversion, impoundment, and pumped storage. Pumped storage plants pump water to a higher reservoir during low demand periods to generate power later by releasing the stored water.

Solar Power
Solar power is energy from the sun that is harnessed and converted into thermal or electrical energy. It can be converted into thermal energy to heat homes, buildings, and water or converted into electricity through photovoltaic cells or concentrating solar power plants. The three main types of concentrating solar power plants are parabolic trough systems, solar dish systems, and solar power tower systems, which use mirrors to focus sunlight to heat a fluid and drive electricity-generating turbines. Solar power provides a renewable energy source without air pollution and can be implemented on various scales.
Fuel Cell Energy
Hydrogen fuel cells generate electricity through the electrochemical reaction of hydrogen and oxygen, producing only water and electricity as byproducts. They have a wide variety of uses in automobiles, processors, power plants, and other applications. A hydrogen fuel cell works by storing hydrogen in a compressed liquid form, fusing the hydrogen with oxygen to produce an electrical charge which is then collected and used to power motors or stored in batteries. Fuel cells are a clean energy source and hydrogen is the most abundant element in the universe.
Science Wind Power
Wind power has a long history dating back to its earliest uses for sailing boats and powering windmills in Persia around 500-900 AD. In the late 19th and early 20th centuries, thousands of farmers in the United States used windmills to pump water. Modern utility-scale wind power development began in the 1970s during the energy crisis, and growth accelerated in the early 1990s with improvements in wind turbine technology that increased reliability and lowered costs. Today, wind is one of the fastest growing sources of clean energy worldwide without producing greenhouse gas emissions.
Tidal Wave
Tidal power harnesses the energy from tidal waves and currents to generate electricity. There are two main types: tidal barrages and tidal stream power. Tidal barrages use large dams and turbines, storing water behind the dam until low tide when it is released to turn the turbines. Tidal stream power uses underwater turbines similar to wind turbines that are turned by fast ocean currents to produce electricity. Both convert the mechanical energy of tidal waves and currents into electrical power by using the flow of water to spin turbines connected to generators.
Wind energy
Wind turbines convert the kinetic energy of wind into electrical energy. The main components include blades, a shaft, generator, and nacelle housed at the top of a tower. As wind blows over the blades, they spin a shaft connected to a generator to produce electricity. Modern wind turbines can start generating at wind speeds of 8-16 mph and shut off at 55 mph to avoid damage from high winds.
Solar Energy
Solar energy comes from the sun's nuclear fusion reactions, sending photons of energy to Earth which can be converted into electricity or thermal energy. Photovoltaic cells convert solar radiation directly into electricity by packing individual cells into modules and arrays, producing DC electricity that can power homes and be sent to the electrical grid. Everyone benefits from solar energy without worrying about its source, and homeowners can lower their electric bills by having some of their needs met by solar power. Solar energy can also be converted to thermal energy to heat water, spaces, or fluids to generate electricity.

Hydroelectric Power
- 2. How it Works Hydroelectric power mostly comes from dams on large rivers with drops in elevation. Water is stored in the reservoir behind the dam. At the bottom of the dam wall there is the water intake, which is caused by gravity. The water then falls through the penstock, which moves a turbine propeller. Then the turbine shaft goes upward into the generator, and the power is produced. Connected to the generator are power lines that carry the electricity to mines and homes. Then the water goes past the propeller into the river and out of the dam.
- 4. How the Generator Works The generator converts mechanical energy into electricty Electromagnets are made from direct current that comes from wire looped around magnetic steel laminations called field poleswhich are mounted on the outside off the rotor Attached to the rotor is the turbine shaft which rotates at a set speed When the rotor turns, electromagnets move past the conductors in the stator, this causes electricity to flow
- 6. Pumped Storage The demand for electricity power isn’t constant, during the day it’s much higher. Using the pumped storage method, water is stored for times of high demand. Water that has already been pumped is put in a storage pool above the power plant during times of low demand. When the demand is high, the water flows back through the turbine generators and energy is produced.
