The reporting on this is ridiculous - although I am of the mind you can use whatever electricity you can pay for.
All that the rules say is that a workstation with 32G RAM (formula is 10 + 0.03 * RAM_GiB) must not exceed ~ 11W in sleep mode and a desktop with 32G RAM must not exceed 6W in sleep mode (5 + 0.03 * RAM_GiB).
"Measured annual energy consumption" is the Energy Star energy consumption criteria. The formula is: 365*24/(1000)*weighted_average_power_consumption (in kWh).
The weighted average power consumption is based on measured power draw in the following states: "off", "sleep", "Long_idle", and "short_idle". Most desktops under the California rules will use the "conventional" weighting factors of (45%, 5%, 15%, 35%) for the respective power modes in that average.
Short idle is basically what you expect. Screen is still on, drives are still spun up.
Long Idle allows basic power saving features to have kicked in (like spinning down hard drives), and assumes the screen has gone blank, but that the computer is still in ACPI G0/S0, not in some form of sleep mode.
