Electric power
Electric power is the amount
of work done by an electric
current in a unit time. When
a current flows in a circuit
with resistance, it does
work. Devices can be made
that convert this work into
heat (electric heaters),

Distributed generation
Distributed generation is a
new trend in the generation
of heat and electrical
power. The concept permits
the "consumer", who is
generating heat or
electricity for their own
needs, to send their surplus
