In 1986, Rocky Mountain Institute (RMI) founders Amory and Hunter Lovins started E Source with the goal of partnering with utilities to help their customers save electricity. Their novel approach defined the art of electric end-use efficiency—better known as energy efficiency.

Working with utilities to create and implement energy-efficiency programs, E Source quickly realized that it had to understand the customer side of these programs. That naturally meant an expansion of E Source’s work to include market research, customer experience, marketing, and communications.

Nearly 35 years later, we’re still helping electric, gas, and water utilities solve their efficiency problems, but we’re taking a different approach. In today’s world, it’s not just about providing a reliable commodity. Utilities must also understand customers’ desire for comfort, productivity, self-reliance, environmental benefits, and security. This creates a need for much more sophisticated data models, predictive data science, and hands-on implementation solutions. To become an even stronger partner with utilities, E Source acquired a number of companies since 2020 that increase our ability to meet your most pressing needs.
