 We are totally new to this, but we are interested in purchasing a tumbler that will tumble glass as well as rocks. So that would be the first question. Next, what about the increase cost to electricity to run these tumblers? Do all tumblers run on electricity only? But then again running on propane or gas might not be powerfully enough...... I am sure that we will have more questions as time goes on but for now we will start with these. Thanks!

the electric cost should not be much. i do not know how big of a tumbler you are getting but if you calculate how much it costs to run 1watt for a month then you can take that times whatever the tumbler uses.
[(1w) * (720H) * ($0.08/KW H)] / (1000) = $ 0.0576/month
so a 50watt tumbler is 50* 0.0576 = $2.88/month
100watt=$5.76
250watt=$14.4

edit: forgot to note you electric rate might differ some. it is 8 cents per kilowatt hour in iowa.

Any tumbler for rocks will handle glass also (not at the same time). Glass is very soft so tumbles fast. You won't notice the electric use unless you get up to large (1/3hp motors and larger). I had a 40lb tumbler for a while and it made a$20-$30 bump in my bill.

A Lortone model 3A (common starter tumbler of decent quality for your stated applications) wil dissipate about 12-16 watts while running depending on the load so it is very economical from an energy cost perspective to run. You will likely be spending most of your operating costs on grit and rough to keep it going, not on electricity.
