From July 2025 through June 2026, fossil fuels supplied almost four-fifths of Indiana’s electricity consumption, while low-carbon sources provided about 18%. Coal accounted for roughly 41% and gas for 35%, making them the dominant sources. Within the clean electricity supply, wind contributed about 9% of consumption and solar almost 8%, mostly from utility-scale installations. Net imports supplied another 3%. Indiana therefore remains heavily dependent on fossil electricity, with substantial scope to expand clean generation and reduce the climate-changing emissions and air pollution associated with fossil fuels.

Is Electricity Growing in Indiana?

Electricity consumption in Indiana is growing: the latest 2026 figure reached about 16,650 kWh per person, exceeding the previous record of about 16,370 kWh in 2025 by 283 kWh, or nearly 2%. Low-carbon electricity generation also set a record, reaching about 2,930 kWh per person, compared with roughly 2,590 kWh in 2025—an increase of about 340 kWh, or 13%. Clean generation growing faster than overall consumption is encouraging, and sustained expansion will help meet additional electricity demand from electrification and AI.

Suggestions

Indiana should accelerate solar deployment, expand wind generation, and consider building nuclear power to increase its low-carbon electricity supply. Neighboring Illinois offers a particularly relevant example: nuclear provides about 49% of electricity generation in that US state. The US state of Michigan also demonstrates nuclear’s regional role, generating about 21% of its electricity from it. For wind, Indiana can learn from the nearby US state of Iowa, where wind supplies 57% of generation. Solar leaders offer further guidance: the US states of Nevada and California generate about 35% and 31% of their electricity from solar, respectively. Drawing on these regions’ experience could help Indiana build a larger, more diverse clean electricity supply.

History

The supplied history shows uneven progress in Indiana’s low-carbon electricity generation from 2024 through 2026. In 2024, wind generation increased by 1.5 TWh, while hydro and low-carbon biofuels each declined by 0.1 TWh. In 2025, wind, hydro, and biofuels generation were all unchanged—a disappointing pause in growth across those sources. Wind growth resumed in 2026 with an additional 0.6 TWh, while hydro and biofuels again remained flat. Wind’s renewed expansion is welcome, but stronger, sustained growth across clean electricity sources would better support Indiana’s future electricity needs.
