In 2024, Connecticut's electricity consumption exhibits a significant reliance on fossil energy, which accounts for more than half of the state's electricity generation. Gas, almost making up the entirety of fossil energy usage, is at 58%. On the other hand, low-carbon or clean energy sources contribute to nearly 41% of electricity generation, with nuclear power being the most substantial at around 37%. The contributions from biofuels, solar, and hydropower are all about 1% each. This mix illustrates a notable dependence on fossil fuels, but also a meaningful involvement from low-carbon sources which is essential for sustainable development.
Is Electricity Growing in Connecticut?
Regarding the growth of electricity consumption in Connecticut, there has been a slight increase. In 2024, the electricity consumption reached 12,288 kWh per person, which is higher compared to the 2021 record of 12,222 kWh per person. This increase of 66 kWh per person, while positive, suggests relatively slow growth which can be insufficient given the escalating energy demands from electrification trends. Particularly alarming is the decline in low-carbon electricity generation from 5,193 kWh per person in 2021 to 5,021 kWh in 2024, showing a drop of 172 kWh. This decline in clean energy is disconcerting amidst growing calls for climate action and the need to reduce reliance on fossil fuels.
Suggestions
Connecticut can amplify its low-carbon electricity generation by focusing on the expansion of its nuclear capacity, as it already plays a significant role in clean electricity generation. Observing successful regions like France and their 68% reliance on nuclear energy and New Hampshire with 56%, Connecticut could further develop its nuclear infrastructure to emulate this success. Additionally, given the promising results from sunny regions like Nevada and their 27% solar power generation, Connecticut can also explore further investments in solar energy. By investing more robustly in these clean energy technologies, Connecticut can meet future demands sustainably while reducing its carbon footprint.
History
Historically, the trajectory of low-carbon electricity in Connecticut has had its ups and downs, particularly with nuclear energy. In the late 2000s, nuclear generation saw fluctuations with both increases and decreases, such as a decrease of 1 TWh in 2005 and an increase of 1.2 TWh in 2009. The 2010s continued with similar inconsistencies—2011 saw a decline of 0.8 TWh, but 2015 had an increase of 1.6 TWh. In more recent years, nuclear generation has experienced significant variability, including a troubling decline of 2.8 TWh in 2023, followed by an impressive rebound with an increase of 3.2 TWh in 2024. The cyclical nature and significant declines in nuclear electricity generation highlight an urgent need for more consistent and robust investment in this critical low-carbon technology, ensuring sustainable growth in clean electricity for Connecticut.
