The “Show Me” State Cooling On Coal!

State Economy

The population of the “Show Me State,” Missouri s approximately 6.19 million people[1]. Missouri is the 18th most populated state in the United States.

In 2022, Missouri’s economy was ranked 22nd in the United States in gross domestic product (GDP)[2]. The state’s economy is dependent on the agriculture, forestry, aerospace, defense, manufacturing, mining, financial services, and publishing industries[3].

Environmental Policies

In 2007, Missouri enacted a Renewable Energy Standard that mandates all investor-owned utilities sell 15% of their electricity from renewable energy sources by 2021[4].

Power Generation Capabilities

In January 2023, utilities[5] used coal (65.0%), nuclear power (14.4%), renewable energy (13.2 %),and natural gas (7.4%) to generate electricity in Missouri. Wind, solar, and biomass are the types of renewable energy used to generate electricity in Missouri.

In January 2023, the average cost of residential electricity in Missouri was 10.73¢ per kWh, compared to the national average of 15.47¢ per kWh.

Recent renewable energy developments in Missouri include:

  • 300 MW Wind Project – In December 2021, Illinois power company, Invenergy commissioned the Atchison Renewable Energy Center at a site in the northwest region of the state.
  • 236 MW Wind Project – In December 2020, Italian power company Enel commissioned the White Cloud wind project, which is located in the northwest region of the state.
  • 200 MW Solar Project – Arizona renewable energy company, Arevon is continuing work on the Kelso solar project at a site approximately 150 miles southeast of the state capital of Jefferson City. The project is forecast to be commissioned by year-end 2023.
  • 200 MW Solar Project – French utility, EDF is continuing work on the Huck Finn Solar project is located in the eastern region of the state. The project is forecast to be commissioned by year-end 2024.
  • 6 MW Community Solar Project – In December 2021, Missouri utility Ameren commissioned a community solar project at a site approximately 50 miles west of the city of St. Louis.


Coal mining began in Missouri in the 1880s[6]. Coal was initially used to fuel steam engines for the railroad, stoves, and forges.

In 2021, Missouri had only one operating coal mine[7], which produced only 44,000 tons of  bituminous coal. Coal for Missouri’s power plants are brought in by rail primarily from Wyoming.

In 2010, Missouri used coal-fueled power plants to generate 82.9 % of the state’s electricity[8]. In January 2023, 65.0 % of the state’s electricity was generated from coal-fueled power plants. Why the decrease?

  1. Pollution – Coal ash, the product of coal burned in a power plant contains arsenic, mercury, and lead; which are toxic. In 2019, coal ash was documented to have leaked into the ground water around 241 coal-fired plants in America[9].
  2. EconomicsThe cost to generate power from coal without subsidies is more than double the cost to generate power from renewables, like solar.
  3. Climate Change Coal generates 40% to 45% more greenhouse gases than natural gas.

Missouri has significant renewable energy resource potential, including wind, solar, and biomass. The economics of low cost, reliable renewable energy has finally spurred state utilities to cool on coal fueled power plants. The “Show Me” state is finally cooling on coal!
