That's an unfair generalization, especially if you're in control of the hardware used. There are some drivers that certainly drain your battery very quickly (I'm looking at you, Broadcom!), but there are other hardware constellations where Linux has a significantly lower power usage than Windows. It's up to the hardware manufacturers to select the right components.
