In the year 2025, Hawaii's electricity consumption reflects a strong reliance on fossil fuels, making up 60% of the state's electricity generation, all of which is derived from oil. This overwhelming dependency on fossil fuels contributes to climate change and air pollution. In contrast, low-carbon energy sources supply a little under a third of the electricity. The largest contribution comes from solar power, accounting for more than 22%, with both behind-the-meter (BTM) and utility-scale solar installations in play. Wind energy, geothermal energy, and biofuels together add more than 8% to the electricity mix. These figures highlight the potential for growth in clean energy production, which is essential for reducing the environmental impact of electricity generation in Hawaii.

Is Electricity Growing in Hawaii?
Hawaii's electricity consumption per person has seen notable growth, indicating a positive trend in the state's electricity development. In 2025, individuals consumed approximately 8086 kWh, surpassing the previous record set in 2024 by 664 kWh per person. This rise in electricity per capita is driven by increased generation from low-carbon sources, which rose to 2575 kWh per person in 2025, marking an uptick of 141 kWh from the year before. This positive growth in both total and clean electricity consumption underlines Hawaii's gradual yet promising shift toward a more sustainable energy landscape.
Suggestions
To further bolster its low-carbon electricity generation, Hawaii can enhance its existing solar capabilities, given the high potential for solar energy in the state. Observing other regions, Hawaii should consider expanding nuclear power, as demonstrated by the success of countries like France and Slovakia, where nuclear energy constitutes more than half of the electricity supply. Additionally, the potential in wind energy is supported by examples from states like Iowa and South Dakota, where wind energy makes up nearly 60% of electricity. Applying insights from these regions, Hawaii can aim to diversify its clean energy portfolio, thereby reducing reliance on fossil fuels while minimizing environmental impacts.
History
Reflecting on the recent history of low-carbon electricity in Hawaii, there have been both advances and setbacks. In 2024, geothermal energy saw a modest increase, while biofuels experienced a decline. By 2025, wind and hydroelectric projects showed slight reductions, suggesting a need for strategic reinvestment or innovation in these sectors. Nevertheless, Hawaii's progressive focus on solar power remains a solid foundation for clean energy growth. As the state continues to evolve, future strategies should prioritize elevating these key areas, drawing lessons from successful regions to enhance both the scale and reliability of its low-carbon electricity generation.
