The answer was potential energy, which surely is wrong. The energy generated is, self evidently, mechanical energy. This can then be used directly or indirectly to generate other forms of energy, typically water flow is converted directly into mechanical then pure electrical energy in a generator turbine, as at a Hydroelectric power station.

it comes from steam
A device used to turn kinetic energy into electricity
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.
Water is allowed to fall from some height into a turbine. The height the water falls increases its kinetic energy. That is why dams are so tall. The turbine rotates. the turbine is mounted on a shaft. The shaft is connected to the shaft of a generator. When the generator is spun by the turbine, it makes electricity. Water actually does not fall but rather flows down stream at high velocity and great pressure. it also saves much more money and if we only use it we will be stoping polution and we can reuse it.
It creates heat, heat boils water in closed boiler into pressurised steam, expanding pressurised steam drives steam turbine blades, steam turbine drives generator creating electricity, electricity powers metro system
Kinetic energy of wind
Read your book, and you will get the answer. :))Bye now.
A turbine spins water creating kinetic (movement) energy. This kinetic energy is changed into electricity through a generator connected to it.
Wind turbines utilize wind energy to convert it to usable electrical energy. Specifically, the kinetic energy of the air molecules spin a turbine within an electromagnetic field, the kinetic energy of the turbine is then converted to electrical energy due to the presence of the electromagnetic field.
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
The potential energy in the head of water is converted into kinetic energy in the turbine which converts the kinetic energy into electrical energy. Potential Energy of water -> Kinetic Energy -> Electrical Energy
The potential energy in the head of water is converted into kinetic energy in the turbine which converts the kinetic energy into electrical energy. Potential Energy of water -> Kinetic Energy -> Electrical Energy
when there is a wave,there is gravitational potential energy,which is converted to kinetic energy,when the water hits the turbine,it creates electrical energy.
That is potential energy when the water is sitting in the dam. The PE is converted into kinetic energy by running the water down a chute to allow it to gain speed, and then it hits the turbine blades to turn the turbine which drives a generator.
Wind contains kinetic energy. When the wind enters the turbine, the kinetic energy is converted to mechanical energy. Then the energy goes through a generator that makes it into electrical energy (electricity).In simpler terms:The wind passing the blades of the turbine spin the shaft that is connected to the generator (kinetic to mechanical energy conversion). The spinning generator produces electricity (mechanical to electric energy conversion).
Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.
When one basically sees the flow system in a power plant, then following formula for is-entropic process is important: h+(V2/2) = constant heat energy is related to 'h'(enthalpy). The conversion of 'h' to 'V'(velocity) takes place in a CD (convergent divergent)nozzle, where the steam expands and 'h' is converted into kinetic energy of steam (in turn steam gets a huge momentum)which turn the steam turbine. So basically the kinetic energy for the steam is developed in CD nozzle itself (from decreasing enthalpy which was generated due to heat energy in super heater or the boilers), which turns the turbine.
