In the period from April 2025 to March 2026, Delaware's electricity consumption primarily relied on net imports, making up more than half of the total consumption at about 56%. This was followed by fossil energy sources, which accounted for roughly 39%, with natural gas comprising nearly all of this fossil energy at about 37%. Low-carbon electricity generation in Delaware was minimal, contributing just about 4% to the total. Solar energy made up the entirety of this green electricity, split nearly equally between behind-the-meter solar projects at around 2% and utility-scale solar at about 1.5%. This stark contrast highlights the significant opportunity for growth in Delaware's clean energy sector.

Is Electricity Growing in Delaware?

Looking at the trends in electricity consumption in Delaware, the current consumption per person in 2026 was recorded at about 12,201 kWh. This number reflects a slight decrease compared to the historic record set in 2024, which was slightly higher at 12,228 kWh, showing a small decrease of 27 kWh per person. On the bright side, Delaware has seen an increase in low-carbon electricity generation per person, with the latest record in 2026 at 429 kWh compared to the previous record of 420 kWh in 2025. While this increase might seem modest, it represents a positive step towards more sustainable energy practices. However, the overall downward trend in total electricity consumption indicates a potential stagnation that could inhibit future growth if not addressed.

Suggestions

To increase its low-carbon electricity generation, Delaware can look towards successful regions for guidance. For example, Illinois generates half of its electricity from nuclear energy, and Iowa produces 57% from wind energy. These states have harnessed the power of existing, mature technologies to achieve high levels of clean electricity generation. Similarly, Delaware could focus on establishing or expanding nuclear and solar facilities, inspired by regions like New Jersey and Nevada, where nuclear and solar contribute significantly to their respective energy mixes. By prioritizing the development of nuclear power and solar energy, Delaware could reduce its reliance on fossil fuels and move towards a cleaner, greener future.

History

Historically, Delaware has shown little change in low-carbon electricity generation from biofuels and wind energy over several years. From 2024 through 2026, there has been no recorded increase in electricity production from these sources. This stagnation highlights a concerning trend, where clean energy development has not met its potential compared to fossil fuels. At a time when climate change and energy security are critical issues, such inertness in adopting more sustainable practices is disappointing. Delaware's limited progress in expanding its clean electricity supply underscores the urgent need for aggressive policies and investments in low-carbon technologies, particularly solar and nuclear, to ensure a more sustainable and independent energy future.
