How are tidal geberators different from hydroelectric plants?
Hydroelectric plants use energy from moving water
What is a hydroelectric plant?
Hydroelectric plants use moving or falling water to turn a generator and produce electricity. They usually have generators located at the base of a dam, and they raise the level of water behind the structure. The higher the water level behind the dam, the more potential energy it has. And by releasing water, the potential energy can be converted into kinetic energy to turn the turbines which turn the generators. The height of the water is called the head of water. Hoover and Grand Coulee Dams are very high, and have a lot of head. Lest you think dams like those are the only dams producing electricity, you should be aware that there are many low head hydros around the country. There are 8 or 9 in Michigan, which is not generally associated with hydroelectric power production. There are a number of others around, too. Long ago, the waterwheel harnessed the power of moving or falling water to provide mechanical energy to turn mill stones or power other machines. As our technology evolved, we extended the idea to make it what it is today. And in the present, we see most big hydroelectric plants in the U.S. located in the west. (Niagra is a bit of an exception.) It's because the geography out west includes the high elevations as well as the water to make dam construction (with the associated hydroelectric plant) possible.
What does turbine spin?
Turbine spins due to mechanical and rotation energy being applied to them. In a wind turbine that energy comes from moving air. Hydroelectric and water mill turbines use the energy from flowing water. Fuel and natural gas can also drive the turbines that generate electricity or provide the thrust needed by aircraft to fly also.
What is a description of an electric motor?

What is a description of a electric motor?
Changes eletrical enegry to mechanical energy. Is found many appliances with moving parts, like a vacum cleaner or a blender.
What type of energy in flowing water?
Mechanical energy, if it is moving then it is kinetic mechanical energy. Or if it is at the top of a hill about to fall then it is potential mechanical energy.
When a hydroelectric plant uses moving water to spin a device that generates electricity one form of energy is transformed into another?
Hydroelectric power is turning the kinetic energy of moving water into electricity
How is wind energy transformed into kinetic energy?
The energy in the wind is kinetic, it is due to a mass of air moving at a certain speed. Wind energy is transformed into mechanical energy through the blades of the wind turbine, and the mechanical energy is then transformed into electrical energy in a generator driven by the blade axis.
In hydroelectric power plants the energy from moving water is converted into electric power. What kind of energy transformation occurs when the energy is converted?
The energy transformation that occurs in hydroelectric power plants is from kinetic energy (movement of water) to mechanical energy (turbine rotation) and then to electrical energy (electricity generation).
What shows that energy is being transformed?
Energy transformation can be detected by changes such as a change in temperature, motion, sound, or light in a system. For example, in a light bulb, electrical energy is transformed into light and heat energy. In a moving car, mechanical energy from the engine is transformed into kinetic energy.
What energy transformation occurs in wind?
In wind energy, the kinetic energy of moving air is converted into mechanical energy when it interacts with the blades of a wind turbine. The mechanical energy is then transformed into electrical energy through the rotation of a generator, which produces electricity.
What kind of energy transformation occurs when the hydroelectric power plants is converted?
In a hydroelectric power plant, the energy transformation that occurs is from mechanical energy (moving water) to electrical energy. Water flow turns a turbine connected to a generator, converting the kinetic energy of the moving water into electrical energy that can be distributed and used to power homes and businesses.
What energy transformation takes place in a windmill?
In a windmill, the kinetic energy of the moving wind is transformed into mechanical energy as the wind turns the blades of the windmill. The mechanical energy is then converted into electrical energy as the blades spin a turbine connected to a generator.
List two ways mechanical energy can be transfomed to nonmechanical energy?
* Moving an object across another can result in heat through friction. This is conversion of the mechanical energy into thermal energy. * In an electric motor, the (mechanical) rotation of the coils results in electrical current and therefore electrical energy.
What energy transfers takes place in a wind turbines?
In a wind turbine, kinetic energy from moving air is converted into mechanical energy when the blades rotate. The mechanical energy is then transferred to a generator, where it is transformed into electrical energy that can be used to power homes and businesses.
What are the energy transformations of the windmill?
Wind energy is converted into mechanical energy when the wind turns the blades of the windmill. The mechanical energy is then transformed into electrical energy through a generator connected to the wind turbine.
What is produced by moving water?
