Thomas Stoner

Thomas H. Stoner, Jr. is an entrepreneur, investor, author and thought leader in the clean energy industry. His career spans from being the first acting director and founding Board member of the Social Venture Network in the 1980s to the current founder and CEO of Entelligent.

In 1990, Mr. Stoner raised $3.5 million to start up Highland Energy Group, Inc., an energy services company, and built the business from zero revenues to $10 million annually by 1997. While there, he contracted and managed dozens of energy services (commonly called “ESCO”) projects with universities, large industrial clients, city and state institutions, and several major medical centers across the country. In 1995, Mr. Stoner sold the company to Eastern Utilities Associates, a $1.7 billion utility company listed on the NYSE, providing a substantial venture capital return to its original shareholders. He was promoted to vice President of the parent company after the acquisition where he supervised and managed three dispersed subsidiary companies until July 1997. During his tenure with EUA Highland and EUA Cogenex, he developed over $50 million in ESCO-type projects primarily through three DSM contracts with Public Service Company of Colorado, Duke Power of North Carolina, and TU Electric of Dallas, Texas, and managed over 120 employees.

From 1998 to 2008, Mr. Stoner served as CEO of Econergy International Corporation successfully leading the Company from a small consulting service to a world-class renewable energy company operating as a power producer throughout the Americas and acting as a technical advisor in more than fifty countries around the globe.  In 2006 Mr. Stoner floated Econergy on the London Stock Exchange AIM market raising nearly $100 million of equity capital. In 2008, Suez South America (SESA), a wholly owned subsidiary of the GDF-Suez Group (a large French water, electric and gas utility, circa €70 billion of annuals revenues) announced its offer to buy Econergy International. At the time of the announcement, Econergy International was a renewable Independent Power Producer (IPP) developing a portfolio of clean energy assets in Latin America and the United States.

In 2013, Mr. Stoner founded Project Butterfly, a research initiative working with leading scientists and energy engineers on the Front Range of Colorado to curate ideas and establish methodologies that address global climate change. Using econometric and financial modeling of the global energy supply, Project Butterfly research demonstrated the viability and financial benefit of moving to an economy powered by higher energy efficiency. In 2013, Mr. Stoner published the results of his research in Small Change, Big Gains: Reflections of an Energy Entrepreneur. His ultimate discovery and message within the book is that the proper path forward for the world’s economies will not only be beneficial to the environment, but also, and more importantly, be beneficial for business.
