Who We Are

3 Rivers Energy is a renewable energy developer that specializes in the creation of renewable natural gas (RNG). We work with companies to provide solutions that convert their bio-waste into renewable energy. We can take renewable energy projects from the “idea” stage to the “shovel ready” stage, to project completion to owner/operatorship.

Our Team

John F. Rivers

Cofounder and CEO


John was the co-founder of Hillstone Environmental Partners, and it was his fourth such successful start-up business in the energy sector. Having started Hillstone in 2015 from scratch with zero accounts to its recent sale of the company for over $600MM, he has been able to secure long term agreements with several notable companies like Exxon, EOG, and Devon to name a few. One of his most recent infrastructure agreements will generate an estimate of more than $1.2 Billion and is considered to be one of the country’s largest of its kind.  John was instrumental in the company achieving recognition since its inception as one of the premier U.S. environmental water handling companies in the energy sector.
