Making efficient use of electricity in the home

Nameplate Output	Minimum Efficiency in Active Mode
0 to 1>	0.49 * Nameplate Output
=1 and =49 W	0.09 * Ln(Nameplate Output) + 0.49
>49 W	0.84
	Maximum Energy Consumption in No-Load Mode
0 to 10>	0.5 W
=10 to = 250 W	0.75 W

Where Ln(Nameplate Output) = Natural Logarithm of the nameplate output expressed in watts.
