Electricity, and how do you make it.

[neuk]

I was thinking about how you would make power in the Twilight world.

The easiest way I could think of would be getting a car alternator and attaching it to some thing. This is based on most families having at least 1 car maybe 2. They cannot all be wrecked, and fuel is a thing of the past for most people.

Wind, a wind turbine could be made simple for any village. Attach the alternator with a belt drive system

Water, water wheel is a steady provider of power which hopefully would always be there. This could also be used to power other tools at the same time. Attach the alternator with a wheel held there by gravity?

The question I have is would 24v (car power source) be useful enough to power anything?
