What state produces the most electricity in the US?

Can you tell me which state in the United States is the largest producer of electricity? I'm curious to know if it's a state with abundant natural resources like coal, oil, or natural gas, or if it's a state that relies heavily on renewable energy sources like solar, wind, or hydroelectric power. I'm also interested in understanding what factors contribute to this state's ability to produce so much electricity and if there are any challenges or limitations that it faces in doing so.
