This resolution asserts that renewable electricity facilities , such as wind and solar, have near-zero operating costs , making them the most economical option for generating power. Conversely, fossil fuel-generating facilities , including those using coal, gas, and oil, incur high operating costs due to fuel and maintenance expenses. The resolution highlights that electricity prices are determined by demand and generation costs, with lower-cost generators typically dispatched first. As the demand for power in the United States is growing, reliance on these higher-cost fossil fuel generators to meet increased demand ultimately drives up wholesale electricity prices .
