Visualizing U.S. Energy Use in One Giant Chart

If you feel like you’ve seen this diagram before, you probably have.

Every year, it’s assembled by the Lawrence Livermore National Laboratory, a research center founded by UC Berkeley and funded primarily by the U.S. Department of Energy.

The ambitious aim is to chart all U.S. energy use in one Sankey diagram, including the original energy source (i.e. nuclear, oil, wind, etc.) as well as the ultimate end use (i.e. residential, commercial, etc.) for the energy that was generated.

U.S. Energy Use in 2018

According to the research center’s most recent published version of the diagram, U.S. energy use totaled 101.2 quads in 2018.

In case you are wondering, a single quad is equal to 1 quadrillion BTUs, with each quad being roughly equivalent to 185 million barrels of crude oil, 8 billion gallons of gasoline, or 1 trillion cubic feet of natural gas.

Here is how the recent figure compares to previous years:

Year	U.S. Energy Consumption	% Fossil Fuels in Mix
2018	101.2 quads	80.2%
2017	97.7 quads	80.0%
2016	97.3 quads	80.8%
2015	97.2 quads	81.6%
2014	98.3 quads	81.6%

As you can see in the table, U.S. energy use has been generally increasing, eventually topping 100 quads per year by 2018. During this time, the total percentage of fossil fuels in the mix has dropped, but only from 81.6% to 80.2%.

Taking a closer look at the data, we can see that the largest percentage increases in the mix have come from solar and wind sources:

Source	2014	2015	2016	2017	2018	Change ('14-'18)
Solar	0.427	0.426	0.587	0.775	0.949	+122%
Wind	1.73	1.78	2.11	2.35	2.53	+46%

Energy use measured in quads (1 quadrillion BTUs)

Solar use has increased 122% since 2014, while wind jumped 46% over the same timeframe. Not surprisingly, energy derived from coal has fallen by 26%.

Dealing With the Rejects

One interesting thing about the diagram is that it also shows rejected energy, which represents the energy that actually gets wasted due to various inefficiencies. In fact, 68% of all energy generated is not harnessed for any productive use.

This makes sense, since gasoline engines are usually only about 20-40% efficient, and even electric engines are 85-90% efficient. Put another way, a certain percentage of energy is always released as heat, sound, light, or other forms that are hard for us to harness.

As electric cars rise in popularity and as modern gas-powered engines also get more efficient, there is hope that the amount of this rejected energy will decrease over time.

Renewable and Battery Installations in the U.S. in 2023

Renewable energy, in particular solar power, is set to shine in 2023. This year, the U.S. plans to get over 80% of its new energy installations from sources like battery, solar, and wind.

The above map uses data from EIA to highlight planned U.S. renewable energy and battery storage installations by state for 2023.

Total U.S. renewable energy and battery installations, broken down by share

Texas and California Leading in Renewable Energy

Nearly every state in the U.S. has plans to produce new clean energy in 2023, but it’s not a surprise to see the two most populous states in the lead of the pack.

Even though the majority of its power comes from natural gas, Texas currently leads the U.S. in planned renewable energy installations. The state also has plans to power nearly 900,000 homes using new wind energy.

California is second, which could be partially attributable to the passing of Title 24, an energy code that makes it compulsory for new buildings to have the equipment necessary to allow the easy installation of solar panels, battery storage, and EV charging.

New solar power in the U.S. isn’t just coming from places like Texas and California. In 2023, Ohio will add 1,917 MW of new nameplate solar capacity, with Nevada and Colorado not far behind.

Top 10 States	Battery (MW)	Solar (MW)	Wind (MW)	Total (MW)
Texas	1,981	6,462	1,941	10,385
California	4,555	4,293	123	8,970
Nevada	678	1,596	0	2,274
Ohio	12	1,917	5	1,934
Colorado	230	1,187	200	1,617
New York	58	509	559	1,125
Wisconsin	4	939	92	1,034
Florida	3	978	0	980
Kansas	0	0	843	843
Illinois	0	363	477	840

The state of New York is also looking to become one of the nation’s leading renewable energy providers. The New York State Energy Research & Development Authority (NYSERDA) is making real strides towards this objective with 11% of the nation’s new wind power projects expected to come online in 2023.

According to the data, New Hampshire is the only state in the U.S. that has no new utility-scale renewable energy installations planned for 2023. However, the state does have plans for a massive hydroelectric plant that should come online in 2024.

Decarbonizing Energy

Renewable energy is considered essential to reduce global warming and CO2 emissions.

In line with the efforts by each state to build new renewable installations, the Biden administration has set a goal of achieving a carbon pollution-free power sector by 2035 and a net zero emissions economy by no later than 2050.

The EIA forecasts the share of U.S. electricity generation from renewable sources rising from 22% in 2022 to 23% in 2023 and to 26% in 2024.
