Guy Warner Chairman & CEO

Guy Warner is the founder and CEO of Pareto Energy LTD, a platinum partner of the US Conference of Mayors that designs and finances peer-to-peer energy networks known as microgrids. Trained as a financial economist, Guy worked for 7 years with the Washington National Tax Service of Price Waterhouse, before founding his own company in 1990.


Guy has worked on more than 100 energy and infrastructural planning engagements and provided financial and strategic planning advice to a number of electric and gas utilities in the United States, Europe and South America. He has served as an economic and energy expert before federal courts and state public utility commissions. Since 1995, Guy has concentrated his work on developing new energy efficiency, renewable energy and on-site power projects, working on more than 40 such projects in North, Central and South America.


Finally, Guy has a long history working on climate change projects. He helped found and fund a not-for profit organization that sponsored a year of youth expeditions that were featured at the 1992 United Nations Climate Change Convention in Rio de Janeiro. Guy also served as a financial advisor on bilateral carbon trades that were successfully registered as part of the US State Department’s Joint Implementation initiative.

John T. TylerCOO

John T. Tyler (Tim) is a founding partner and Director of Pareto Energy, Ltd. and serves as the Chief Operating Officer (COO.) He helped found Pareto Energy in 2004 with the goal of introducing microgrids to provide highly reliable, high quality on-site electric power, using the utility grid for back-up power. Tim later realized that the Pareto approach to microgrids could be critical in providing security against a cyber-attack on the utility grid infrastructure and potentially to restore base systems affected by cyber-attack to pre-attack configuration. Additionally, he handles Pareto‘s port related projects, introducing “local power” concepts into the planning and implementation of Port expansion projects, including digital age economic development in Port areas. These projects include on-site power to address Homeland Security issues, maritime infrastructure and cold-ironing to achieve immediate and dramatic emissions reductions. Tim is also involved in introducing Pareto Energy’s EID concepts to the United Kingdom.


Prior to co-founding Pareto, Tim spent over twenty years with the US Government as a senior executive. He served on a White House Task Force and with the US Mission to NATO in Brussels as the senior defense planner; developed unique business structures for extremely large weapons systems sales; and led multi-billion dollar debt restructurings for Turkey, Jordan, Israel, Honduras and other countries. Additionally, he was a partner in BeeTect, which proved that honeybees could be conditioned to detect high explosives. Tim has a BA and MA from Yale University.
