Visualizing U.S. Energy Consumption in One Chart

Visualizing U.S. Energy Consumption in One Chart

Every year, the Lawrence Livermore National Laboratory, a federal research facility funded by the Department of Energy and UC Berkeley, puts out a fascinating Sankey diagram that shows the fate of all energy that gets generated and consumed in the United States in a given year.

Today’s visualization is the summary of energy consumption for 2017, but you can see previous years going all the way back to 2010 on their website.

Dealing in Quads

The first thing you’ll notice about this Sankey is that it uses an unfamiliar unit of measurement: the quad.

Each quad is equal to a quadrillion BTUs, and it’s roughly comparable to the following:

  • 8,007,000,000 gallons (US) of gasoline
  • 293,071,000,000 kilowatt-hours (kWh)
  • 36,000,000 tonnes of coal
  • 970,434,000,000 cubic feet of natural gas
  • 25,200,000 tonnes of oil
  • 252,000,000 tonnes of TNT
  • 13.3 tonnes of uranium-235

Put another way, a quad is a massive unit that only is useful in measuring something like national energy consumption – and in this case, the total amount of energy used by the country was 97.7 quadrillion BTUs.

Energy Wasted

On the diagram, one thing that is immediately noticeable is that a whopping 68% of all energy is actually rejected energy, or energy that gets wasted through various inefficiencies.

It’s quite eye-opening to look at this data sorted by sector:

SectorEnd-Use EfficiencyRejected Energy (Quads)
Residential65%3.75
Commercial65%3.15
Industrial49%12.9
Transportation21%22.2

The transportation sector used 28.1 quads of energy in 2017, about 28.8% of the total consumption. However, it wasted 22.2 quads of that energy with its poor efficiency rate, which made for more rejected energy than the other three sectors combined.

This wastage and inefficiency in the transportation sector provides an interesting lens from which to view the green energy revolution, and it also helps explain the vision that Elon Musk has for the future of Tesla.

A Ways to Go

The last time we posted a version of this visualization was for the 2015 edition of the diagram, and we noted that renewables had a ways to go as a factor in the whole energy mix.

Here are how things have changed over the last two years:

Energy2015 (Quads)2017 (Quads)2-yr change
Petroleum35.436.22.3%
Natural Gas28.328.0-1.1%
Coal15.714.0-10.8%
Nuclear8.348.421.0%
Biomass4.724.914.0%
Hydro2.392.7715.9%
Wind1.822.3529.1%
Solar0.5320.77545.7%
Geothermal0.2240.211-5.8%

As you can see, solar and wind consumption are jumping considerably – but in absolute terms, our note from two years ago still remains true.

To make the desired impact, renewable energy still has a ways to go.

Ranked: The Top 10 EV Battery Manufacturers in 2023

Asia dominates this ranking of the world’s largest EV battery manufacturers in 2023.

The Top 10 EV Battery Manufacturers in 2023

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.

In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.

Chinese Dominance

Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.

The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and various Li Auto models.

Farasis Energy🇨🇳 China16,5272%
Envision AESC🇨🇳 China8,3421%
Sunwoda🇨🇳 China6,9791%
Other-56,0408%

In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.

The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.

Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.

Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.
