In 2022, the state consumed approximately 475 terawatt-hours of electricity, with an average monthly consumption of 1,132 kilowatt-hours. Texas also has the highest electricity bills in the country, with an average monthly cost of $138.56. The deregulated energy market in Texas allows consumers to choose from a variety of providers and shop for lower electric rates.

Texas is also the top producer of electricity in the U.S., accounting for 12.94% of the nation's total energy production in March. The state has a significant capacity for wind energy generation, with 18,500 megawatts of electricity produced through wind power. Texas expects to add another 5,000 megawatts of wind generation capacity from facilities under construction.

In addition to wind power, Texas relies heavily on oil and gas for its energy production. The state is known for its abundant natural resources, including large deposits of oil and natural gas. The use of these fossil fuels has made Texas a major player in the energy industry, with a significant contribution to the nation's total energy output.

While Texas leads in electricity production and consumption, it also faces challenges in meeting the demand for energy, especially during peak periods. The state has invested in energy efficiency (EE) programs and demand response initiatives to optimize its energy infrastructure. Texas is also exploring renewable energy sources, such as wind and solar power, to diversify its energy portfolio and reduce its reliance on non-renewable resources.

Overall, Texas plays a crucial role in the electricity landscape of the United States, with its high consumption, production, and ongoing efforts to balance energy supply and demand. The state's focus on oil and gas has shaped its energy sector, while also driving the exploration of alternative energy sources to meet the growing need for renewable energy.

California: solar leader, high imports

California is a leader in solar energy production in the US. In April 2025, California's solar farms and small-scale solar power systems generated 8,238 thousand megawatt-hours, the highest in the country. In March of the same year, California produced the highest percentage of its electricity from solar of any state. Despite this, California is the second-largest consumer of electricity in the US, consuming approximately 250 terawatt-hours in 2022.

California's high electricity consumption is due in part to the state having the most utility customers of any state, with 13.4 million customers in 2020. However, on average, those customers kept consumption low, with an average consumption of 572 kWh per month, resulting in an average monthly bill of $134.08. This is lower than the average monthly bill in Hawaii, which is $102, and the second-highest in the nation.

California's electricity market is deregulated, meaning consumers can choose from a variety of providers and shop for low electric rates. This may help to explain why, despite having the second-highest electric rates in the nation in 2020, California residents only paid the 15th-highest electricity bills.

To reduce electricity demand from the power grid, California has invested in energy efficiency (EE) programs that promote the use of energy-efficient appliances, lighting, and advanced cooling and heating technologies. The state has also made spending billions of dollars on making solar energy affordable for consumers a top priority. These efforts have resulted in over 3,600 MW of demand capacity resources, reducing electricity demand from California's power grid by more than 11%.

Washington: cheap hydro, low rates

Washington state has one of the lowest average electricity rates in the US, thanks to its abundant hydroelectric power. Hydro is one of the cleanest forms of energy production, and Washington's heavy reliance on hydroelectricity has kept its energy costs low. In contrast, states with higher electricity rates, such as Hawaii, tend to have more regulations, fewer generation assets, or be in a remote location.

Hydroelectric power accounted for 6.6% of the national energy mix in March, and Washington is a significant producer. The state's electricity rates are consistently low due to its abundant hydroelectric resources.

The type of generation resources impacts energy costs, and Washington benefits from its access to clean, renewable hydroelectric power. In contrast, states that rely more heavily on traditional carbon-based power plants, such as coal, petroleum, or natural gas, may have higher energy costs.

Washington's low electricity rates are also a result of its energy infrastructure and transmission systems. The state has invested in efficient transmission lines and distribution networks, reducing the cost of delivering electricity to consumers.

Washington's example highlights the benefits of investing in renewable energy sources and efficient energy infrastructure. By leveraging its natural resources and focusing on efficient energy transmission, Washington has achieved low electricity rates, providing both environmental and economic benefits to its residents.
