I was told by an Asplundh tree trimming supervisor the standard used by most power companies is 18 feet, not 18 inches. Asplundh is a line clearance contractor that works for many power companies in the US, Canada, Australia, and New Zealand.
In CA, General Order 95 (GO-95) states that radial clearances of bare line conductors up to 22.5kV (22,500 volts) from tree branches or foliage is 18" (I'm looking at the GO-95 specs as I type this; Table 1, case 13). Higher voltages are typically Transmission, and are usually on very tall poles/towers, and as such are not normally an issue for tree clearance. As Dutch said, those clearances are based on a formula rather than a fixed number, and are more based on clearances between the lines themselves rather than between the lines and vegetation.

I am not as familiar with the rest of the country, since they go by NESC rather than CA's GO-95, but generally speaking, GO-95 is usually even stricter than NESC. In a cursory search, I can find no reference to clearances from trees in the current NESC.

Living in Florida, we use our RV as an emergency venue in case of hurricanes. We keep the waste tanks empty, water and fuel tanks full so we can live in it in all its self contained glory. Saved us from installing a home generator as many neighbors have done at a cost of tens of thousands of dollars. There have been times when we lost power for up to 4 days and we were completely comfortable in the RV. Of course it could be longer. We can dry camp for at least 10 days before we would have to find dump and fill facilities.
