Aren't high voltage transmission lines just about the most efficient means of power transmission we know?

By raising the voltage, [...]
Although modern power transmission techniques seek to minimize this loss, it cannot be completely eliminated.

Does this mean there is a more efficient way of transporting electrical power?

So the question remains: would locating a generator or fuel-cell on site be more energy efficient than transmitting the power through the grid?

I would say a generator pretty certainly not. The effeciency of trucking in fuel to run the generator is a distant, distant second to high voltage lines, is it not? It seems to me that alone is a pretty much insurmountable setback in efficiency, and I don't see where we could recover it once we consume the fuel in a local generator.

I don't know enough about fuel cells to comment, but considering that high voltage lines are already pretty efficient, they (fuel cells) certainly have a high standard to meet or beat.

As you can see, it's quite difficult to accurately quantify grid loss, especially since energy on the grid is gotten from a constantly changing list of contributing power plants.

Yes, depending on how precise you want to be, but I think for comparison with other techniques as might be employed in this scenario, there's enough to go on, don't you think?
