Nearly 46,000 workers across 4,500 companies propel Connecticut’s clean economy, according to state’s fifth Clean Energy Industry Report from the Joint Committee of the Energy Efficiency Board and the Connecticut Green Bank Board of Directors

Hartford, CT (May 20, 2025) - Connecticut's clean energy industry in 2023 contributed more than $7.01 billion to the state's Gross Regional Product (GRP) while jobs in this sector grew by 3.9 percent. This job growth accounted for 7.5 percent of Connecticut's total statewide employment growth between 2022 and 2023, significantly outpacing the state's overall employment growth, according to the recently released 2024 Connecticut Clean Energy Industry Report. The sector has nearly surpassed 46,000 workers, climbing above pre-Covid-19 employment levels, and the state has more than 4,500 companies working in the clean energy sector. The energy efficiency subsector remains the largest technology sector in the state's clean energy industry and was the primary driver of job growth.

This is the fifth industry study produced by the Connecticut Green Bank, Department of Energy and Environmental Protection, Eversource, and United Illuminating, Southern Connecticut Gas and Connecticut Natural Gas, subsidiaries of Avangrid Inc., operating through the Joint Committee of the Energy Efficiency Board (EEB).

"The clean energy industry continues to grow its impact in our state, adding well-paying jobs and bolstering the state's economy. While the numbers are important, we must also mention the value that these workers and companies provide to our families, businesses, and communities, especially those in the energy efficiency subsector who are helping people save money and reduce the energy cost burden," said Brenda Watson, Executive Director at the North Hartford Partnership and Chair of Connecticut Green Bank and Energy Efficiency Board joint subcommittee. "Despite positive trends in employment growth, challenges remain in filling skilled labor positions and bringing females and historically marginalized groups into the clean energy sector. As advocates, we need to prioritize these areas of potential growth and continue to support programs that sustain this demand for workers."

This analysis from BW Research shows employment divided into five major technology sectors, their component sub-technologies, and industry or value chain segment. The five sectors are: energy efficiency; clean energy generation; alternative transportation; clean grid and storage; and clean fuels. All employment data presented is based on the 2024 United States Energy and Employment Report (USEER).

Some other key findings include:
• Clean energy job growth in Connecticut since last year's Clean Energy Industry Report was the strongest it has been since 2015.
• Connecticut's clean energy employment growth outpaced that of other Northeastern states between 2022 and 2023.
• Connecticut's clean energy industry expanded across all technology sectors from 2022 to 2023, and the fastest-growing sectors - Alternative Transportation (16.3 percent), Clean Grid and Storage (7.6 percent), and Clean Energy Generation (7.1 percent) - outpaced national growth rates.
• Between 2022 and 2023, clean energy employment grew across all value chain segments in Connecticut, with the largest job gains in Construction, Other Services, and Professional and Business Services.
• The clean energy economy accounted for 2.4 percent, or $7.01 billion, of Connecticut's GRP in 2023. This is a 3.1 percent increase from 2022, which is a similar increase to the prior year (3.2 percent).
• As of 2023, more than 4,500 clean energy companies, firms, and establishments exist within Connecticut.
