Generators & Turbines

Turbines transforms kinetic energy to mechanical energy
& Generators transform mechanical energy to electrical energy.

So usually they are used together, eg. in windmills, etc.

Scale-up & adapt to whatever rotary action (from water, wind, steam...) you have available to generate renewable energy.
