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.

Support the Future of Data Storytelling

Sorry to interrupt your reading, but we have a favor to ask. At Visual Capitalist we believe in a world where data can be understood by everyone. That’s why we want to build the VC App - the first app of its kind combining verifiable and transparent data with beautiful, memorable visuals. All available for free.

As a small, independent media company we don’t have the expertise in-house or the funds to build an app like this. So we’re asking our community to help us raise funds on Kickstarter.

How Affordable is Gas in Latin America?

This graphic looks at gas affordability in Latin America, showing how much a liter of gas costs in 19 countries, relative to average incomes.

How Affordable is Gas in Latin America?

As gas prices have risen around the world, not each region and country is impacted equally.

Globally, the average price for a liter of gas was $1.44 USD on June 13, 2022.

But the actual price at the pump, and how affordable that price is for residents, varies greatly from country to country. This is especially true in Latin America, a region widely regarded as one of the world’s most unequal regions in terms of its income and resource distribution.

Using monthly data from GlobalPetrolPrices.com as of May 2022, this graphic by Latinometrics compares gas affordability in different countries across Latin America.

Gas Affordability in 19 Different Latin American Countries

To measure gas affordability, Latinometrics took the price of a liter of gas in 19 different Latin American countries and territories, and divided those figures by each country’s average daily income, using salary data from Statista.

Out of the 19 regions included in the dataset, Venezuela has the most affordable gas on the list. In Venezuela, a liter of gas is equivalent to roughly 1.3% of the country’s average daily income.

CountryGas price as of May 2022 (USD)% of average daily income
🇳🇮 Nicaragua$1.3714.0%
​🇩🇴​ Dominican Republic$1.4112.6%
🇧🇷​ Brazil$1.4312.5%
🇵🇾​ Paraguay$1.3912.2%
🇵🇪 Peru$1.5310.2%
🇺🇾 Uruguay$1.929.8%
🇸🇻​ El Salvador$1.149.2%
​​🇭🇳​ Honduras$1.338.6%
🇲🇽​ Mexico$1.177.8%
🇬🇹​ Guatemala$1.447.7%
🇦🇷 Argentina$1.066.7%
​🇨🇱​ Chile$1.376.6%
🇨🇷​ Costa Rica$1.425.9%
🇨🇴 Colombia$0.585.7%
​🇵🇦 ​Panama$1.275.0%
🇪🇨 Ecuador$0.674.1%
🇧🇴 Bolivia$0.543.2%
🇵🇷​ Puerto Rico$1.352.2%
🇻🇪​ Venezuela$0.021.3%

This isn’t too surprising, as Venezuela is home to the largest share of proven oil reserves in the world. However, it’s worth noting that international sanctions against Venezuelan oil, largely because of political corruption, have hampered the once prosperous sector in the country.

On the other end of the spectrum, Nicaragua has the least affordable gas on the list, with one liter of gas costing 14% of the average daily income in the country.

Historically, the Nicaraguan government has not regulated gas prices in the country, but in light of the current global energy crisis triggered in large part by the Russia-Ukraine conflict, the government has stepped in to help control the situation.

As the Russia-Ukraine conflict continues with no end in sight, it’ll be interesting to see where prices are at in the next few months.

Mapped: Which Ports are Receiving the Most Russian Fossil Fuel Shipments?

Russia’s energy exports have become a hot topic. See which ports received fossil shipments during the first 100 days of the Ukraine invasion

Published

As the invasion of Ukraine wears on, European countries are scrambling to find alternatives to Russian fossil fuels.

In fact, an estimated 93% of Russian oil sales to the EU are due to be eliminated by the end of the year, and many countries have seen their imports of Russian gas plummet. Despite this, Russia earned €93 billion in revenue from fossil fuel exports in the first 100 days of the invasion.

While the bulk of fossil fuels travel through Europe via pipelines, there are still a number marine shipments moving between ports. The maps below, using data from MarineTraffic.com and Datalastic, compiled by the Centre for Research on Energy and Clean Air (CREA), are a look at Russia’s fossil fuel shipments during the first 100 days of the invasion.

Russia’s Crude Oil Shipments

Much of Russia’s marine shipments of crude oil went to the Netherlands and Italy, but crude was also shipped as far away as India and South Korea.

India became a significant importer of Russian crude oil, buying 18% of the country’s exports (up from just 1%). From a big picture perspective, India and China now account for about half of Russia’s marine-based oil exports.

It’s important to note that a broad mix of companies were involved in shipping this oil, with some of the companies tapering their trade activity with Russia over time. Even as shipments begin to shift away from Europe though, European tankers are still doing the majority of the shipping.

Russia’s Liquefied Natural Gas Shipments

Unlike the gas that flows along the many pipeline routes traversing Europe, liquefied natural gas (LNG) is cooled down to a liquid form for ease and safety of transport by sea. Below, we can see that shipments went to a variety of destinations in Europe and Asia.

Fluxys terminals in France and Belgium stand out as the main destinations for Russian LNG deliveries.

Russia’s Oil Product Shipments

For crude oil tankers and LNG tankers, the type of cargo is known. For this dataset, CREA assumed that oil products tankers and oil/chemical tankers were carrying oil products.

Huge ports in Rotterdam and Antwerp, which house major refineries, were the destination for many of these oil products. Some shipments also went to destinations around the Mediterranean as well.

All of the top ports in this category were located within the vicinity of Europe.

Russia’s Coal Shipments

Finally, we look at marine-based coal shipments from Russia. For this category, CREA identified 25 “coal export terminals” within Russian ports. These are specific port locations that are associated with loading coal, so when a vessel takes on cargo at one of these locations, it is assumed that the shipment is a coal shipment.

The European Union has proposed a Russian coal ban that is expected to take effect in August. While this may seem like a slow reaction, it’s one example of how the invasion of Ukraine is throwing large-scale, complex supply chains into disarray.

With such a heavy reliance on Russian fossil fuels, the EU will be have a busy year trying to secure substitute fuels – particularly if the conflict in Ukraine continues to drag on.
