Last year, the amount of electricity generated from renewable sources in Illinois and the surrounding Midwest states decreased, despite efforts to transition away from fossil fuels like coal and natural gas in favor of wind and solar power. Climate change may have played a role in this unexpected outcome.
Wind power, the largest source of renewable energy in the state, saw a surprising 6 percent decrease in electricity generation, while natural gas-generated electricity experienced a 43 percent increase in 2023, according to government data. A pressure system in Canada, which also contributed to wildfires and smoky skies in Chicago, impacted wind power by affecting wind direction and speed, leading to a decline in energy production from wind turbines across Illinois.
Researchers are studying the impact of climate change on wind power, as fluctuations in wind speed can significantly impact energy generation. While wind power decreased last year, solar power saw significant growth, although it still contributes a small percentage to Illinois’ electricity generation. The state’s reliance on nuclear power also saw a slight decrease, while coal continued its decline due to plant closures.
Despite the decrease in wind power generation, advocates are optimistic about the potential for solar energy in Illinois. The state’s goal of eliminating fossil-fuel power by 2050 has led to investments in wind farms and solar power development. However, uncertainties remain regarding the future energy mix after phasing out coal and gas.
While wind developers are seeking to understand future wind patterns, experts emphasize the importance of continuing investments in wind and solar energy. Variability in wind speeds should not deter investments, as renewable energy remains crucial for combating climate change. State officials aim for renewable energy generation to increase annually, despite potential fluctuations in wind and solar energy production.
