how would you explain how energy is made from alternative forms to a fourth grader ?

how electrical energy is made from alternative form of energy
(wind,solar,geo-thermal)

For alternative energy that comes from something that moves like geothermal, hydro, wind, tidal, you say that the stuff flows through a turbine, which has blades like an airplane propeller, and that turns a generator, like the one on your bike that runs the light. There are several kinds of solar, and some heat water to drive a turbine. You don’t have to explain how solar cells work – you can point to a solar calculator, and say that this patch produces electricity, and it can be done with really big patches.

Fourth graders know how to do math, like multiply and divide. That’s pretty sophisticated.
