Depends on what you mean by powerful. How many horsepower? And are we taking about electric motors or petrol or diesel or turbines, or what?
An electric car is normally powered by a motor, but can be driven with gas turbines, or jet engines, to either increase the range or feed power directly to the wheels.
Wind turbines create energy in a similar way as a hydro-electric dam. Wind turns the fan blades, which drive a motor that converts the kinetic energy into electric energy.
Power stations, hydro electric schemes, aircraft engines, wind turbines.
hydro electric energy
The electric motor changes electric energy into mechanical energy.
Moving water (dams, rivers, tides) and turbines (like an electric motor in reverse) that will produce electricity when the moving water spins them round.
Alternators are not only driven by turbines, they can be alternator can be driven by any prime mover -including 'motors' if necessary.
Wind turbines with electric generators
electric energy to mechanical energy
it comes from turbines and generators.
To make hydro-electric energy.
