Do all currents provide the same amount of energy?

Of course not! There is no direct relationship between electric current and electric energy. They aren't even measured in the same units. Also in most cases small electric currents provide less electric energy that very large electric currents. If all electric currents provided the same electric energy then the electric current from a flashlight battery that lights the bulb when you turn the switch on could provide the same electric energy as the electric current in a lightning bolt when it strikes... therefore every time you turned on a flashlight the electric energy would destroy the flashlight and electrocute you! As this doesn't happen, the only answer that your question can have is no!


If an alternator supplies electricity to an electric motor that spins the alternator will it run forever?

Yes, you could connect these parts together and it would operate. But after awhile you will find that the batteries are running low and the will motor is run slower than initially. The answer to the specific question is "no - you could not do this to generate electricity endlessly". If you could, that would constitute a perpetual motion machine, and that is impossible to do, due to losses in energy conversion because nothing is perfectly efficient.

The current in an electric motor comes from?

Power plants (fueled by elements) produce the electrical energy that circuits to an outlet that you can charge an electric motor with a plug that is wired to an electric motor. Or if it is a vehicle with an electric motor, you electrically charge car batteries that produce the current to the electric motor.

Do hybrids use re-newable or non-renewable resources?

The hybrids I know are vehicles which have a gasoline engine and also electric storage batteries. The batteries can provide propulsion in town, the engine takes over on the open road. All the energy comes from the gasoline consumed, so that is non-renewable. Hybrids could also use electricity from the grid to charge the batteries when the vehicle is garaged, which would reduce the amount of gasoline used, but not eliminate it. The grid electricity could partly come from renewable sources. Fully electric vehicles can be made but they have limited range.
