There are several models that are viable for reading electricity meters and for distributing electricity bills.
One viable model for reading electricity meters would be the one in which human labor is used: so that meter readers are sent out to go around reading the meters. This is the traditional approach, and while it has its advantages, it is inefficient in terms of cost, and many power companies are doing away with it.
The other viable model for reading electricity meters would be the one in which satellite technology is used to obtain the readings, on whose basis then electricity bills are calculated.
Turning to the distribution of the electricity bills, the first model that can be used is that in which the bills are distributed through the postal system. This is the traditional way of doing things.
The other viable model for distribution of electricity bills is the one in which the bills are distributed using the Internet. If, for instance, a given electricity user has a Yahoo Mail (www.yahoomail.com) account, set up as per the instructions given in this post, it should be possible for the electricity company to sent him or her bills through the email, so that no printing and postage costs are incurred.
