The Road To Decarbonization: Visualizing The United States Electricity Mix
The U.S. response to climate change and decarbonization is ramping up, and putting a focus on the country’s electricity mix.
As pressure has increased for near-term and immediate action after the UN’s latest IPCC report on climate change, major economies are starting to make bolder pledges. For the United States, Visual Capitalist’s Omri Wallach notes that includes a carbon pollution-free utilities sector by 2035.
But with 50 states and even more territories—each with different energy sources readily available and utilized—some parts of the U.S. are a lot closer to carbon-free electricity than others.
How does each state’s electricity mix compare? This infographic from the National Public Utilities Council highlights the energy sources used for electricity in U.S. states during 2020, using data from the U.S. Energy Information Administration.
The U.S. Electricity Generation Mix By State
How does the United States generate electricity currently?
Over the course of 2020, the U.S. generated 4,009 TWh of electricity, with the majority coming from fossil fuels. Natural gas (40.3%) was the biggest source of electricity for the country, accounting for more than nuclear (19.7%) and coal (17.3%) combined.
Including nuclear energy, non-fossil fuels made up 41.9% of U.S. electricity generation in 2020. The biggest sources of renewable electricity in the U.S. were wind (8.4%) and hydro (7.3%).
But on a state-by-state breakdown, we can see just how different the electricity mix is across the country (rounded to the nearest percentage).
At a glance, regional availability of a fuel source and historical use is clear.
For example, coal is the most-used electricity source in West Virginia, Kentucky, and Wyoming, historical coal rich regions and economies.
On the flip side, the Pacific Northwest and New England generated the most hydroelectricity, and the biggest producers of wind energy were all located in the Great Plains. Even the biggest percentage producers of solar and geothermal energy, California and Nevada, have plenty of access to sunlight and geothermal activity.
The Changing Electricity Landscape
But for the U.S. to reach its ambitious carbon-free goal by 2035, the biggest impact will need to come from the biggest electricity producers.
That title currently goes to Texas, which generated 12% of total U.S. electricity in 2020. Despite being the most populous state, California generated less than half Texas’ output, and less than both Florida and Pennsylvania.
So although it’s positive that many states in the Pacific Northwest and New England have more plentiful non-fossil fuel electricity, their overall impact on the total U.S. picture is lessened.
Still, more and more states (and countries) are increasing their efforts and ambitions to decarbonize, and that progress makes it easier and more affordable over time. States that might struggle to attain carbon-free electricity, or where costs are too high, face less hurdles as technology improves and subsidies increase.
And with most major U.S. based utilities focusing on improving their ESG reporting and keeping up with decarbonization pledges of their own, the total electricity mix is expected to shift rapidly over the next decade.
