ELI5- why do we need to find different ways to generate electricity if the main thing is turning the turbine? Can’t people turn it manually?

Some turbines rotors weight hundreds of millions of pounds. You aren’t spinning that with your (or a few thousand of your friends) hands.
Basically all the arguments about green energy are about how to spin that turbine.
And they do kinda turn it manually. They just use water or steam to do it.
