About Us

Empowering Communities with Energy Efficiency Since 2002

Founded in 2002 by our company president, Basudev Mukherjee, Global Energy Services (GES) began as a one-man operation and has grown into a leading provider of energy efficiency solutions across Southern California.

​

Over the years, we’ve built strong, lasting relationships within the communities we serve, partnering with SoCalGas, Southern California Edison, and San Diego Gas & Electric to deliver no-cost energy-saving upgrades to qualifying homeowners.

​

At Global Energy Services, we go beyond energy efficiency—we empower homeowners with valuable insights on no-cost installation measures, rebates, and incentives available through our utility partners. Our mission is to make sustainable living accessible to all, with a strong focus on underserved communities.

​

GES is committed to reaching underserved populations, where language barriers may pose challenges. Through our in-language programs, we actively raise awareness, ensuring that more residents can take full advantage of the energy-saving opportunities we offer through our partnerships with leading utility companies.
