Cheaper, greener.   Perhaps cheaper is the more important here.

Fibre is much cheaper and less energy intensive to make and far less  
energy to run than copper.  So far it has been the terminations and  
optical transceivers that are more expensive.  I imagine this will  
change eventually.  For instance if nearly every household in  
Australia has one - it might help bring the price down.
