Sean Casten represents Illinois’ 6th Congressional District, located in Chicago’s western suburbs. He is serving in the 117th Congress. First elected in 2018, he is the first Democrat to represent the 6th District in nearly 50 years.

Sean is committed to fighting to build a brighter, more sustainable future. Since taking office, he has introduced and co-sponsored legislation in support of clean energy, women’s rights, protections for seniors, and universal health care, among other critically-important issues.

Sean currently serves on the House Financial Services Committee, the Science, Space, and Technology Committee, the Select Climate Crisis Committee, and is a Co-Chair on the New Dems Climate Change Task Force.

Prior to his election to Congress, Sean co-founded and led Recycled Energy Development, which focused on recycling wasted energy and converting energy facilities to cleaner, more economic uses. Earlier in his career, he served as the president and CEO of Turbosteam Corporation, which used energy recycling technologies to reduce greenhouse gas emissions. Sean has also advocated for clean energy policies and has authored articles on clean energy technology, energy policy, and energy regulation.

While working diligently in Washington on behalf of the 6th District, Sean is committed to keeping in close contact with his constituents, and hold frequent town halls so that he can remain in touch with the views of people across the district.

Sean and his wife Kara live in Downers Grove, Illinois, with their two daughters.

As a scientist, Sean has dedicated his life to fighting climate change

Sean earned a B.A. in Molecular Biology and Biochemistry from Middlebury College. He then worked for two years as a scientist at the Tufts School of Medicine in a laboratory investigating dietary impacts on colon and breast cancer.

In 1998, he earned a Masters of Engineering Management and a M.S. in Biochemical Engineering from the Thayer School of Engineering at Dartmouth. His M.S. thesis was focused on the development of technologies to produce fuel-grade ethanol from cellulosic feedstocks and the techno-economic evaluation of various alternative ethanol, heat, and power generation technologies.

From 1997 to 2000, Sean worked as a consultant in the energy practice of Arthur D. Little, where he worked for a broad range of public and private sector companies doing work to evaluate, design, and optimize a broad range of clean heat, power, and fuel technologies.

Sean has created jobs here in the district and across America

In 2000, Sean became the president and CEO of Turbosteam Corporation, a manufacturer of custom-built combined heat and power plants, all of which achieved at least double the fuel efficiency of the U.S. electric grid. Under Sean’s leadership, the company sold, installed, and commissioned over 70 distinct power plants throughout the Americas and Asia, with a primary focus on the U.S. industrial sector.

In 2007, Sean moved to Illinois to co-found Recycled Energy Development, LLC (“RED”), with a mission to profitably reduce greenhouse gas emissions through the recovery of otherwise wasted energy.

Sean has advocated for pragmatic policy solutions

Sean was the founding (2005) chairman of the Northeast Combined Heat and Power Association, an advocacy organization that acted to aggregate the interests of over 50 clean energy businesses on regulatory and utility cases throughout the New York and New England regions.

Sean also served as the 2007 chairman of the U.S. Combined Heat and Power Association (USCHPA), a national trade association.

Sean has testified before the Senate Energy Committee, was a lead negotiator in the development of the Massachusetts (electric grid) Interconnection Standards and has provided expert testimony to multiple state and federal energy and environmental regulatory agencies.

Sean has been recognized as a community leader

Sean currently serves on the Thayer School of Engineering’s Corporate Collaboration Council, working with faculty and staff to help ensure the professional quality of their M.E.M. degree program and helping students secure internships and long-term employment.

In 2005, the USCHPA recognized Sean as a “CHP Champion” for his work advocating the greater use of clean, efficient heat and power generation. In 2009, Sean was recognized as an “Emerging Leader” by the Chicago Council on Global Affairs.

He has completed 10 marathons and represented Team USA in a 2012 duathlon in Switzerland that required a 10K run, a 150K bike ride, and a further 30K run. He has coached youth soccer in Downers Grove and plays in several cover bands of varying degrees of quality.
