From September 2024 to August 2025, Delaware's electricity consumption primarily relied on net imports and fossil fuels, with clean energy sources contributing minimally. The state imported nearly 60% of its electricity from outside, while more than a third came from fossil fuels, predominantly gas, which accounted for about 32%. Solar energy, a low-carbon source, contributed marginally, making up only about 3% of the total electricity. Close to none of the electricity production came from other low-carbon sources, suggesting a significant reliance on non-sustainable energy options, with fossil sources like coal contributing an additional small share in the energy mix.

Is Electricity Growing in Delaware?

Delaware's electricity consumption pattern reveals a concerning decrease in overall usage over the years. The most recent figures show 12,034 kWh per person in 2025, a significant drop from the peak of 16,006 kWh per person in 2005—a reduction of close to 4,000 kWh per person. On a brighter note, low-carbon electricity generation has slightly improved, with the latest figure at 414 kWh per person, up by 14 from the previous record in 2023. While this reflects some progress in clean energy adoption, the overall decline in electricity consumption should be addressed to support future electrification demands.

Suggestions

To increase low-carbon electricity generation, Delaware can look towards states like New Jersey and regions like Nevada that have successfully embraced nuclear and solar energy. New Jersey generates a substantial portion of its electricity from nuclear power, contributing a notable 33%. Meanwhile, Nevada's extensive solar generation at 33% demonstrates the viability of expanding solar capabilities. By investing in nuclear energy and solar infrastructure, Delaware could significantly boost its clean energy share. Learning from these successful models, Delaware can leverage nuclear and solar to minimize its reliance on fossil fuels, thereby reducing its environmental footprint while meeting growing electricity demands.

History

Reviewing Delaware's historical low-carbon electricity data reveals limited progress. The contribution from biofuels remained stagnant from 2007 through 2025, with no significant increases in production. Solar energy made its first appearance as contributing in 2012, but there has been minimal movement since its initial introduction. The lack of substantial progress in low-carbon electricity generation over several years highlights a need for strategic action to boost Delaware's clean energy profile. Increasing electricity from sustainable and green sources such as solar and nuclear would place Delaware on a path towards a more resilient and environmentally friendly energy future.
