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.
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:
|Sector||End-Use Efficiency||Rejected Energy (Quads)|
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:
|Energy||2015 (Quads)||2017 (Quads)||2-yr change|
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.
Animation: The Entire History of Tesla in 5 Minutes
Everything you need to know about the history of Tesla, including Elon Musk’s vision for the future of the iconic electric car company.
How did Tesla accelerate from 0-60 mph in such a short period of time?
Today’s five-minute-long animation is presented in association with Global Energy Metals, and it tells you everything you need to know about the history of Tesla, including Elon Musk’s vision for the future of the iconic electric car company.

How Much Copper is in an Electric Vehicle?
Have you ever wondered how much copper is in an electric vehicle? This infographic shows the metal’s properties as well as the quantity of copper used.
How Much Copper is in an Electric Vehicle?
Copper’s special relationship with electricity has been apparent since ship designers first regularly began installing copper to protect the masts of wooden ships from lightning in the early 19th century.
Today, of course, you might be more used to seeing copper’s electrical applications through the use of power lines, telephone wires, and wiring in practically every major home appliance you own.
Millions of tons get used for these applications every year, but it is still early days for copper’s use in electrification. That’s because copper will continue to be a critical component of the green energy revolution, thanks to the rising adoption of battery-powered vehicles.
Today’s visualization comes to us from Canadian Platinum Corp., and it focuses on showing how much copper is in an electric vehicle, along with the properties that make it the ideal choice for an EV-powered future.
Here is why copper is a crucial component to vehicle manufacturers:
Copper costs roughly $0.20 per ounce, compared to silver ($15/oz) and gold ($1200/oz), making it by far the cheapest option for electrical wire.
Copper is nearly as conductive as silver – the most conductive metal – but comes at a fraction of the cost.
Copper can easily be shaped into wire, which is important for most electrical applications.
It’s also important to note that temperature does not affect copper’s conductivity, which makes the metal ideal for automobiles in all climates.
Copper in Gas vs. Electric Vehicles
The UBS Evidence Lab tore apart a traditional gas-powered vehicle as well as an EV to compare the different quantities of raw materials used.
What they found was crucial: there is 80% more copper in a Chevrolet Bolt, in comparison to a similar-sized Volkswagen Golf.
The major reason for this is that at the heart of every EV is an electric motor, which is built with copper, steel, and permanent magnets (rare earths). Electric motors tend to be much simpler than gas-powered engines, which have hundreds of moving parts.
Incredibly, in an electric motor, there can be more than a mile of copper wiring inside the stator.
The More Electric, the More Copper
According to Copper.org, along the scale from gas-powered cars to fully electrical vehicles, copper use increases dramatically.
Conventional gas-powered cars contain 18 to 49 lbs. of copper while a battery-powered EV contains 183 lbs. Meanwhile, for a fully electrical bus, a whopping 814 lbs. of copper is needed.
With the rapidly increasing adoption of electric vehicles, copper will be an essential material for the coming electrification of all forms of ground transport.
Copper is at the heart of the electric vehicle and the world will need more. By 2027, copper demand stemming from EVs is expected to increase by 1.7 million tonnes, which is a number just shy of China’s entire copper production in 2017.
