Running trains and electricity costs?

[nachoman]

Down here the biggest problem is running the A/C when the temperature outside is 96, the humidity can be cut with a dull #11 Xacto and the Heat Index is 106!

I hear ya! not to get off-topic, but a good portion of your AC load is removing moisture from the air. That pesky "heat of vaporization" must be overcome in order to cool a humid air mass below it's dew point. You can save some energy by setting your thermostat lower at night when your AC is more efficient, and then raising the thermostat during the day. If your house is well-insulated, the house will take longer to heat up in the morning and your A/C won't have to run as much during the day. When I look at how much of my bill goes to summer AC, almost all other electric usage (such as trains) is negligible.
