Would old wiring increase your electric usage if you have a 1940s house with a new breaker box but old wiring in the walls with very high electric bills even without the air on?

Old wiring can definitely contribute to high electric bills. It is also unsafe even with a new breaker box. We did ours recently and it made our bills go down substantially. Chances are, your 1940's house was built with lath and plaster so it is a pain to get to the old wiring. The best thing is to just have the old wiring cut off and have new wiring put in. The dead wiring behind the walls won't hurt anything since there is no power connected to it. Best thing to do: get an electrician to examine your situation to determine the best solution. Many will do a free consultation.
Old wiring doesn't offer greater resistance to current flow which is what would increase consumption. In fact the wire gauge used in 1940 is larger than is generally used in modern homes. I think replacing the wire is a good idea since the wire insulation used in 1940 has a tendency to deteriorate which can create a very hazardous situation but I would be very surprised if your electric bill went down. Although replacing the panel is also a good idea since whatever was there had to be an antique I do not understand how that lowered your bill.
It is a good idea to pull out the old wire which should be fairly easy to do but if it is completely dead it is likely to be safe to abandon it.

Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
What is the function of the fuse or circuit breaker in a circuit?

Do some electrical breakers when they are tripped go into the off position instead of the normal tripped position I have a cutler hammer breaker that tripped but is in the off position?
Some breakers can trip totally off. If the breaker is continually turning off without a wiring issue, then the breaker could be going bad.
Can you use a 20 amp circuit breaker for an electric dryer?
If you are referring to a cloths dryer, the answer depends on the requirements of the dryer. Most dryers require AWG#10 wire with a 30 amp fuse. If the wiring is AWG#12 then use a 20 amp breaker but never use it on AWG#10 which requires a 30 amp breaker. If you are referring to a hair dryer then yes a 20 amp breaker is fine.
Why do you need a double 30A pole for an electric dryer if you only have one pole left in your box?
The dryer is 220VAC. You need a double pole breaker to get 220 out of a home breaker panel. Perhaps you should contact an electrician who understands wiring so that you don't burn your house down.
