The U.S. Department of Energy said it canceled a loan guarantee for the multistate transmission project because it was not a responsible use of taxpayer money. Missouri Sen. Josh Hawley had advocated for the cancellation.

The bill has dozens of policy changes that affect how utility companies are allowed to operate and charge customers in Missouri.

Together, the three new solar facilities can produce 500 megawatts of renewable energy. They are the energy companies largest solar effort to date.

Each step on the Pet Power walkway produces three joules of electricity that will be collected in batteries donated to the APA Adoption Center.

The Cass County Renewable Energy Center will double the size of a program that allows large businesses to pay for renewable energy.

Ameren Missouri has announced plans to expand its Community Solar program with a third solar facility to meet growing demand for renewable energy.

Solar power is the fastest growing source of electricity in the U.S., but some new solar installations are taking over productive farm ground. Scientists are trying to develop ways to get both calories and kilowatts from the same land, but it's not as easy as it might seem.

Missouri Republicans for years have criticized the use of eminent domain to build high-voltage transmission lines.
