Our Sources of Energy
The Power Mix:
Where does power come from
and what are its components?

What we believe
Market forces, economic pressures, and
environmental regulations are all moving
toward a path of fewer but cleaner traditional
central power plants and more distributed
energy resources.
NRG believes that the future of energy is
partnering with like-minded organizations
to help them achieve their reliability
and clean energy goals.
