Electromechanics: Unit of comparable magnitude to electricity needed for a modern home?

Hi!

I'm trying to figure out an elementary question about electricity. I don't go to well trying to understand the circular definitions of Joules, Ohms, Watts, Volts and all that...

I was wondering, in terms of comparable magnitude of force, what is the amount of electricity necessary for a house. Is there a unit of measurement that compares to that?

For example, would it be possible to hook-up a dynamo to a stationary bike and supply a household complete with television, stove and all?

I was pondering this while observing natural forces around a property, I was feeling the breeze and wondering; how strong of a gale does it take to supply a family household and how big would the turbine/blades have to be?

(I get these questions in my head all the time)

I observed the st-laurent river the other day and its whirling currents on the surface of the water and thought: "If we put some palms on a wheel and placed it on that channeled current, how much hydrodynamics would that create, and how much electrical current would that create... I wonder"

I know its not a simple question, and that because I don't have a basic grasp of the subject, I can't formulate it precisely, but I hope you understand what I mean.

Thank you!
