All U.S. Energy Consumption in a Giant Diagram
Today’s graphic is special type of flow chart, called a Sankey diagram.
This particular one shows the total estimated energy consumption in the United States in 2015, and how energy flowed from source to the final destination. The graphic comes to us from the Lawrence Livermore National Laboratory and the Department of Energy.
The beauty of a Sankey is in its simplicity and and effectiveness. No information is left out, and we can really see the full energy picture from a 10,000 foot view.
Wasted Effort
The U.S. is estimated to have consumed 97.5 quads of energy in 2015.
What’s a quad? It’s equal to a quadrillion BTUs, which is roughly comparable to any of these:
- 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
It’s a lot of energy – and if you look at the diagram, you’ll see most of it is actually wasted.
It’s estimated that 59.1 quads (60.6% of all energy) is “rejected energy”, a fancy term for energy that is produced but not used in an effective way. For example, when gasoline is burned in a car, most of the energy comes off as heat instead of doing productive work (ie. turning the crank shaft). The average internal combustion engine is only 20% efficient, and people get excited even when they approach 40% efficiency.
While gas engines are horribly inefficient, so are other energy sources. If you look at electricity production on the diagram, you’ll see that 67% of all energy going to generate electricity is wasted.
It’s the laws of physics, but there are still many areas for improvement to increase this efficiency.
A Long Way to Go for Green Energy
As we explained in Part 2 of our Battery Series, there are still some big obstacles to overcome for green energy, batteries, and energy storage.
By looking at all energy use (including non-electrical energy used in automobiles, industrial, etc.), this diagram helps put things in even more perspective. To make a big impact, green energy not only has to make inroads in electrical generation, but it also has to supplant the 25.4 quads of energy being used in the automotive sector. This is why projects like the massive Tesla Gigafactory 1 are such a big deal. If Elon Musk is successful in his mission, the whole diagram and our energy mix would change dramatically.
For now, however, green is still a blip on the radar. Looking at total energy consumption in 2015, solar only accounted for 0.53 quads of energy. Meanwhile, wind accounted for 1.82 quads.

Charted: 4 Reasons Why Lithium Could Be the Next Gold Rush
Visual Capitalist has partnered with EnergyX to show why drops in prices and growing demand may make now the right time to invest in lithium.
4 Reasons Why You Should Invest in Lithium
Lithium’s importance in powering EVs makes it a linchpin of the clean energy transition and one of the world’s most precious minerals.
In this graphic, Visual Capitalist partnered with EnergyX to explore why now may be the time to invest in lithium.
1. Lithium Prices Have Dropped
One of the most critical aspects of evaluating an investment is ensuring that the asset’s value is higher than its price would indicate. Lithium is integral to powering EVs, and, prices have fallen fast over the last year:
Date | LiOH·H₂O* | Li₂CO₃** |
---|---|---|
Feb 2023 | $76 | $71 |
March 2023 | $71 | $61 |
Apr 2023 | $43 | $33 |
May 2023 | $43 | $33 |
June 2023 | $47 | $45 |
July 2023 | $44 | $40 |
Aug 2023 | $35 | $35 |
Sept 2023 | $28 | $27 |
Oct 2023 | $24 | $23 |
Nov 2023 | $21 | $21 |
Dec 2023 | $17 | $16 |
Jan 2024 | $14 | $15 |
Feb 2024 | $13 | $14 |
Note: Monthly spot prices were taken as close to the 14th of each month as possible.

**Lithium carbonate MB-LI-0029
2. Lithium-Ion Battery Prices Are Also Falling
The drop in lithium prices is just one reason to invest in the metal. Increasing economies of scale, coupled with low commodity prices, have caused the cost of lithium-ion batteries to drop significantly as well.
In fact, BNEF reports that between 2013 and 2023, the price of a Li-ion battery dropped by 82%.
Year | Price per KWh |
---|---|
2023 | $139 |
2022 | $161 |
2021 | $150 |
2020 | $160 |
2019 | $183 |
2018 | $211 |
2017 | $258 |
2016 | $345 |
2015 | $448 |
2014 | $692 |
2013 | $780 |
3. EV Adoption is Sustainable
One of the best reasons to invest in lithium is that EVs, one of the main drivers behind the demand for lithium, have reached a price point similar to that of traditional vehicle.
According to the Kelly Blue Book, Tesla’s average transaction price dropped by 25% between 2022 and 2023, bringing it in line with many other major manufacturers and showing that EVs are a realistic transport option from a consumer price perspective.
Manufacturer | September 2022 | September 2023 |
---|---|---|
BMW | $69,000 | $72,000 |
Ford | $54,000 | $56,000 |
Volkswagon | $54,000 | $56,000 |
General Motors | $52,000 | $53,000 |
Tesla | $68,000 | $51,000 |
4. Electricity Demand in Transport is Growing
As EVs become an accessible transport option, there’s an investment opportunity in lithium. But possibly the best reason to invest in lithium is that the IEA reports global demand for the electricity in transport could grow dramatically by 2030:
Transport Type | 2022 | 2025 | 2030 |
---|---|---|---|
Buses 🚌 | 23,000 GWh | 50,000 GWh | 130,000 GWh |
Cars 🚙 | 65,000 GWh | 200,000 GWh | 570,000 GWh |
Trucks 🛻 | 4,000 GWh | 15,000 GWh | 94,000 GWh |
Vans 🚐 | 6,000 GWh | 16,000 GWh | 72,000 GWh |
The Lithium Investment Opportunity
Lithium presents a potentially classic investment opportunity. Lithium and battery prices have dropped significantly, and recently, EVs have reached a price point similar to other vehicles. By 2030, the demand for clean energy, especially in transport, will grow dramatically.
With prices dropping and demand skyrocketing, now is the time to invest in lithium.
EnergyX is poised to exploit lithium demand with cutting-edge lithium extraction technology capable of extracting 300% more lithium than current processes.
