The Connecticut Department of Energy and Environmental Protection (DEEP) has prepared an update to Connecticut’s Comprehensive Energy Strategy (CES) to advance the State’s goal of creating a cheaper, cleaner, more reliable energy future for Connecticut’s residents and businesses. By statute, DEEP is required to periodically update the CES plan for all energy needs in the state, including, but not limited to, electricity, heating, cooling, and transportation. This CES analyzes energy use and key trends across these sectors, and it reports on progress made since 2013. Based on the analysis, DEEP made recommendations on eight priority strategies to guide administrative and legislative action over the next several years.
