A power management device, including: a monitor module that directly
monitors energy usage of at least one energy load to generate at least
one measurement of energy usage by the at least one energy load; and a
control module operatively coupled to the monitor module to control
energy usage by the at least one energy load in a pre-determined manner
that is based on the at least one measurement of energy usage, wherein
the control module controls the at least one energy load via a data link.
