Connecticut's current electricity consumption is heavily reliant on fossil energy, contributing more than half of the state's electricity, with gas being the primary source at almost 59%. In contrast, low-carbon energy sources account for nearly 40% of electricity consumption, showcasing a commitment to cleaner energy. Nuclear power leads the low-carbon category, providing a substantial 36% of the electricity. While biofuels and solar energy are part of Connecticut’s low-carbon portfolio, their contributions are quite minimal, each providing a little over 1%. This energy profile indicates a clear reliance on fossil fuels, with a notable but insufficient presence of clean energy in Connecticut’s electricity mix over the past year, spanning from June 2024 to May 2025.
Is Electricity Growing in Connecticut?
Electricity consumption in Connecticut appears to be experiencing a decline, which is concerning given the urgent need to transition towards clean energy sources. The state's latest total electricity consumption stands at 12,013 kWh per person, down from a previous record of 12,288 kWh per person in 2024, reflecting a decrease of 274 kWh. Similarly, low-carbon electricity generation has faced a setback, decreasing by 434 kWh per person from the previous peak in 2021. This decline contrasts sharply with the goals of increasing clean electricity generation to meet future demands and tackle climate change, suggesting that the state must take strategic actions to reverse this trend.
Suggestions
For Connecticut to enhance its low-carbon electricity generation, a significant expansion of its existing nuclear infrastructure could prove advantageous, considering nuclear power's substantial contribution to the state's current energy mix. Learning from other regions with successful clean energy strategies, such as New Hampshire and Illinois, where nuclear power comprises over 50% of electricity generation, could provide valuable insights. Additionally, exploring and investing in solar energy, as seen in regions like Nevada and Lebanon, where solar energy contributes approximately 29% and 31% of electricity, respectively, could further boost Connecticut's clean electricity production. This more diversified approach would strengthen the state's resilience against fossil fuel dependency and promote sustainable growth in electricity generation.
History
Connecticut’s history with low-carbon electricity generation has seen fluctuations, particularly with nuclear energy. In the early 2000s, there were a few years of modest declines in nuclear output, yet these were interspersed by periods of growth. For example, there was significant growth in 2009 and 2012 with increases of over 1 TWh each year, followed by notable reductions in 2014 and 2020. Interestingly, 2023 witnessed a decline of nearly 3 TWh, marking a concerning dip. However, 2024 saw a dramatic increase in nuclear output by over 3 TWh, signaling a renewed focus on this important low-carbon energy source. Hydro and biofuels have had minor roles, with slight increases and decreases over the years. The state's fluctuating commitment to nuclear energy reflects a need for a more consistent and strategic focus on expanding its clean electricity sources.
