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.
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.
Mapped: Fossil Fuel Production by Country
These four animated cartograms show the nations leading the world in fossil fuel production, in terms of oil, gas, coal, and total hydrocarbons.
Fossil fuels exist as a double-edged sword for most countries.
On one hand, they still make up a dominant piece of the current energy mix, and oil is still seen as a crucial resource for achieving geopolitical significance. It’s also no secret that fossil fuels are a driver for many economies around the world.
But with governments and corporations counting carbon emissions and mounting concerns about climate change, reliance on these same fuels will not last forever. As attitudes and policies evolve, they will continue to see a reduced role going forward.
Visualizing Fossil Fuels by Country
So, which countries are pumping out the most hydrocarbons?
Today’s cartograms come from 911Metallurgist, and the animated maps resize each country based on their share of global fossil fuel production.
Below, you’ll see four cartograms that cover oil, gas, coal, and total fossil fuel production.
Crude Oil Production
The United States leads this category, producing about 18% of the world’s total oil:
Although the U.S. is the number one producer globally, it should be noted that the country doesn’t have the same quantity of oil reserves as other leading nations.
Weirdly, Venezuela has the exact opposite problem. The country has the most oil reserves in the world, but currently only sits as its 12th biggest producer.
Natural Gas Production
In terms of gas, the U.S. leads again with a 20% share of global production. Russia is also a gas powerhouse, with a 17.3% share.
After the U.S. and Russia, it’s a fairly steep dropoff in terms of natural gas production. Countries like Iran, Canada, Qatar, and China are the next most significant players, but they each only produce 4-6% of the global total.
Coal use may be on the decline, but China still produces a whopping 45% of the world’s coal.
China’s current relationship with coal is an interesting one.
Every year, coal has become less important in China’s energy mix – in 2011 it represented 70% of energy consumption, and by 2018 it had fell to 59%.
Despite this meaningful progress, China’s economy has grown so fast, that coal use has essentially held steady in absolute terms. Meanwhile, the country’s production of coal has actually grown slightly over the same timeframe.
Total Fossil Fuel Production
Finally, here is the sum of all three above categories, converted to metric tonnes:
The United States produces 20% of all global fossil fuels, with Russia and Iran rounding out the top three. After that comes Canada, which produces just under 5% of all fossil fuels globally.
Animation: U.S. Electric Vehicle Sales (2010-19)
This stunning animation visualizes the last nine years of U.S. electric vehicle sales. We also look at who will lead the race in the coming years.
It’s challenging to get ahead, but it’s even harder to stay ahead.
For companies looking to create a sustainable competitive advantage in a fast-moving, capital intensive, and nascent sector like manufacturing electric vehicles, this is a simple reality that must be accounted for.
Every milestone achieved is met with the onset of new and more sophisticated competitors – and as the industry grows, the stakes grow higher and the market gets further de-risked. Then, the real 800-lb gorillas start to climb their way in, making competition even more fierce.
Visualizing U.S. EV Sales
Today’s animation uses data from InsideEVs to show almost nine years of U.S. sales in the electric vehicle market, sorted by model of car.
It paints a picture of a rapidly evolving market with many new competitors sweeping in to try and claim a stake. You can see the leads of early successes eroded away, the increasing value of scale, and consumer preferences, all rolled into one nifty animation.
The Tesla Roadster starts with a very early lead, but is soon replaced by the Nissan Leaf and Chevrolet Volt, which are the most sold models in the U.S. from 2011-2016.
Closer to the end, the Tesla Model S rises fast to eventually surpass the Leaf by the end of 2017. Finally, the scale of the rollout of the Tesla Model 3 is put into real perspective, as it quickly jumps past all other models in the span of roughly one year.
The Gorilla Search
While Tesla’s rise has been well-documented, it’s also unclear how long the company can maintain an EV leadership position in the North American market.
As carmakers double-down on EVs as their future foundations, many well-capitalized competitors are entering the fray with serious and ambitious plans to make a dent in the market.
In the previous animation, you can already see there are multiple models from BMW, Volkswagen, Honda, Fiat, Ford, Toyota, Nissan, and Chevrolet that have accumulated over 10,000 sales – and as these manufacturers continue to pour capital in the sector, they are likely posturing to try and find how to create the next mass market EV.
Of these, Volkswagen seems to be the most bullish on a global transition to EVs, and the company is expecting to have 50 fully electric models by 2025 while investing $40 billion into new EV technologies (such as batteries) along the way.
The Chinese Bigfoot?
However, the 800-lb gorilla could come from the other side of the Pacific as well.
Source: The Driven
Chinese company BYD – which is backed by Warren Buffett – is currently the largest EV manufacturer in the world, selling 250,000 EVs in 2018.
The Chinese carmaker quietly manufacturers buses in the U.S. already, and it has also announced future plans to sell its cars in the U.S. as well.
How will such an animation of cumulative U.S. EV sales look in the future? In such a rapidly evolving space, it seems it could go any which way.
