So Shatner is looking for charitable donations to provide water to one of the richest regions on the face of the planet? Seriously? Is he going to back this campaign with a video of slow-mo shots of people suffering in the OC because their lawn is looking a little brown and the water level in their swimming pools is slightly lower than they'd like. "The people of Beverly Hills are slightly uncomfortable -- let's make their lives better."

Yes, but that's a different issue -- too much electricity in a local zone, rather than too much electricity overall.

Let's take water as our analogy. Water flows to meet demand in the form of open taps. But very few of those taps are strictly regulating, and the outflow is a function of how far the tap is opened and the pressure in the system. Put more water into the mains and the pressure goes up, therefore more water is delivered at the tap. If your house has pressure regulating valves, you won't see this, but the pressure is then further increased at someone else's house.

Put power into the grid, and it *will* be delivered somewhere. If nowhere else will accept the load, it ends up being delivered as heat in the transformer in your local substation. How do you prevent substation fires? Fuses/breakers on the transformers... but that just kills one part of the circuit, and the power ends up getting delivered to another transformer. This sort of rolling blow-out used to be a problem -- one substation blows, leading to another blowing and another blowing and so on, and various power companies the world over have put a lot of time, energy and money into developing systems to prevent it happening.

Have the Germans found a way to eliminate the need to "dump" electricity? Last I knew, every country in the developed world needed to connect their circuits to earth (en_US: ground) in order to bleed off the excess when demand suddenly fell (eg right after the advert break in a popular soap -- lots of kettles go on suddenly, and within three minutes everyone's back in front of the TV).

...they're going to reach the point of needing to charge you a flat fee just for the connection to the power lines...

That is really the way it should be. There is no reason to meter electricity anymore.

If electricity was "free", people would be less likely to switch stuff off. Metering manipulates demand.

Nuclear plants need months to cycle up or cycle down. Traditional thermal plants take days to cycle up or down. Modern plants for flexible demand cycle up and down in a matter of hours. In all of these cases, the flexibility relies on predictability. Power cycles that fluctuate from minute to minute are impossible to predict.
