Energy grid

Since I'm not going to attend the monday meeting I thought I'd share my view of the energy/power idea.
I envision a physical "sim city", but with stuff like power plants of different types(Nuclear, water, solar, wind etc). They have different characteristics and drawbacks like different amount of power produced, different cost of electricity, different amounts of pollution, nuclear waste etc.
The power plants are connected by an electricity grid to houses and industry that uses the electricity. The more electricity is used the more power plants needs to be connected and the more pollution and other bad effects will appear.
This could be made as a model landscape with little powerplants and houses that you can connect to the power grid. There should also be a display or some other solution to indicate pollution and energy use.
The lessoned learned should be a better understanding for how electricity is generated and also what the effects are if we use a lot of it.

Another very different direction would be to explain generators that is the basis for all electricity generation and maybe show the similarity to electric motors. Also powering a generator with "muscle force" could give a sense of how much energy is needed to drive different things.
