Or "LessPower", but that seems somehow to run counter to what people usually want...

Or, "Cooler". We all like cool, right? Right?

You don't want to use less power (watts), you want to use less energy (joules, or kilowatt-hours). Hey, way to get the comments from the pedantic grammar weenies _and_ the pedantic science weenies!

"Power vs energy" is not pedantic

In large part because Intel concentrated on power (increasing CPU clock frequency and maximum instruction issue rate) while AMD concentrated on energy (doing customer work), billions of dollars in sales migrated from Intel to AMD, and thousands of Intel employees lost their jobs. That's not pedantic, that's as practical as one can get.

LessWattage

On the right track, but... Power [measured in watts] is free. What matters is ENERGY [measured in watt seconds or kilowatt hours], which is the integral of power with respect to time. Shame on Intel for making such a technical blunder.

It is reasonable to use more power, sporadically and briefly, in order to make better decisions which lower the total energy expended.

In laptop batteries, where ordinary people would come into contact with the units it's generally watt hours or (since the nominal voltage is fixed with a regulator) just amp hours for a specified voltage.

For a while the GNOME power stuff got this all upside down, showing remaining energy in watts, and current power use in watt hours, but this seems to have been fixed eventually.

> What matters is ENERGY

sure, but if a given laptop battery contains a certain amount
of energy, if you can work with less power, then you can work
longer, right?
