Reduce the Cost of energy by employing Direct Coupling Technology and use the energy from lowest cost resources. Nextek power systems use all available energy from locally generated sources and then then 'fills in' with power from the DC microgrid.

10. “I’d put my money on sun and solar energy.
What a source of power! I hope we don’t have
to wait until oil and coal run out before we
tackle that."
~Thomas Edison, 1880’s
