How electricity meters work?

Can anybody tell me how an electricity meter works? And also what would happen if instead of using the ground wire that comes from the pole you used as ground a wire driven to the ground in the house?
Thanks in advance,

First of all,if you don't know that much about electrical hookups,it would be wise to get a licenced electrician to keep your butt alive..Most local codes require a ground rod driven under the meter socket away from the foundation in undisturbed earth. The meter socket,breaker panel,phone,and cable should all be tied together around that point. The neutral from the socket back to the transformer is the return current path which is also tied to the ground at the pole(or in the pad) and also attached to the surge arrester to protect your house from lightning and spikes. Hopefully you don't have an old house with a two wire system and a fuse box grounded to the galvanized water pipes. If so,you need serious updating.

Grounding is ensuring all metal parts have the same potential as the ground. If they become energized with electricity it will flow through the ground wire (conductor) back to the point where all the grounding conductors and the grounded (neutral) conductor are connected together and back to the transformer causing a short circuit and opening your circuit breaker or fuse.
Your meter only measures the amount of electricity you are using and is not affected by whether it is connected to the earth or to your grounding system.
These are safety issues, not performance issues.
