Electricity Overview

Colorado has many energy resources, including coal, natural gas, solar, and other renewables. To generate electricity, these resources must be converted to electrical energy. For example, the chemical energy embedded in fossil fuels is combusted to generate heat. That heat produces steam, which turns a turbine, generating electricity. By comparison, wind directly turns a turbine to produce electricity by converting kinetic energy to electrical energy.

Colorado’s electricity comes predominantly from fossil fuel power plants. However, since the passage of Amendment 37 in 2004, renewable energy has increased from 2% to more than 18% of total electricity generated.

Electricity is delivered to Coloradans across the state through the electrical grid, which is a network of generators, transmission lines, and distribution lines. Electric utilities maintain the grid, providing reliable electric service to homes and businesses.
