About Us

Our Experience

i3 Energy was founded by Sandra Blackwood and Nathan Baer and our approach to energy efficiency is based off 50+ years of combined experience designing and implementing EE programs as owners of Staples & Associates/Staples Energy.


What We Do

We’re an energy efficiency company focused on assisting gas and electric utilities with achieving their energy saving and sustainability goals. We accomplish this by developing networks of contractors who are focused on energy efficiency installations. We also provide database-driven software to simplify the application process for contractors and customers alike. The knowledge of our in-the-field energy advisors is based on decades of hands-on experience with lighting, refrigeration, compressed air, and heating & cooling equipment. Our team is focused on Inclusion, Integration, and Innovation (i3) to help our clients achieve their goals.
