I was asked recently if utility company claims that the telemetry/usage data from gas/water/power meters that transmit their data rather than being read manually is safe from snooping are actually true.

I can't speak for all meters in this category, but the reality is that for a great many of them the data transmissions are openly available unencrypted (in the U.S., typically in the 900Mhz band), can be received with a cheap RTLSDR dongle, and the software to decode the signals is all over the Net.
