Visualizing America’s Energy Use, in One Giant Chart
Have you ever wondered where the country’s energy comes from, and how exactly it gets used?
Luckily, the Lawrence Livermore National Laboratory (LLNL) crunches the numbers every year, outputting an incredible flow diagram that covers the broad spectrum of U.S. energy use.
The 2019 version of this comprehensive diagram gives us an in-depth picture of the U.S. energy ecosystem, showing not only where energy originates by fuel source (i.e. wind, oil, natural gas, etc.) but also how it’s ultimately consumed by sector.
In Perspective: 2019 Energy Use
Below, we’ll use the unit of quads, with each quad worth 1 quadrillion BTUs, to compare data for the last five years of energy use in the United States. Each quad has roughly the same amount of energy as contained in 185 million barrels of crude oil.
|Year||Energy Consumption||Change (yoy)||Fossil Fuels in Mix|
Interestingly, overall energy use in the U.S. actually decreased to 100.2 quads in 2019, similar to a decrease last seen in 2015.
It’s also worth noting that the percentage of fossil fuels used in the 2019 energy mix decreased by 0.2% from last year to make up 80.0% of the total. This effectively negates the small rise of fossil fuel usage that occurred in 2018.
Energy Use by Source
Which sources of energy are seeing more use, as a percentage of the total energy mix?
Since 2015, natural gas has grown from 29% to 32% of the U.S. energy mix — while coal’s role in the mix has dropped by 4.7%.
In these terms, it can be hard to see growth in renewables, but looking at the data in more absolute terms can tell a different story. For example, in 2015 solar added 0.532 quads of energy to the mix, while in 2019 it accounted for 1.04 quads — a 95% increase.
Finally, let’s take a look at where energy goes by end consumption, and whether or not this is evolving over time.
Residential, commercial, and industrial sectors are all increasing their use of energy, while the transportation sector is seeing a drop in energy use — likely thanks to more fuel efficient cars, EVs, public transport, and other factors.
The COVID-19 Effect on Energy Use
The energy mix is incredibly difficult to change overnight, so over the years these flow diagrams created by the Lawrence Livermore National Laboratory (LLNL) have not changed much.
One exception to this will be in 2020, which has seen an unprecedented shutdown of the global economy. As a result, imagining the next iteration of this energy flow diagram is basically anybody’s guess.
We can likely all agree that it’ll include increased levels of energy consumption in households and shortfalls everywhere else, especially in the transportation sector. However, the total amount of energy used — and where it comes from — might be a significant deviation from past years.
Mapped: The World’s Nuclear Reactor Landscape
Which countries are turning to nuclear energy, and which are turning away? Mapping and breaking down the world’s nuclear reactor landscape.
The World’s Changing Nuclear Reactor Landscape

Following the 2011 Fukushima nuclear disaster in Japan, the most severe nuclear accident since Chernobyl, many nations reiterated their intent to wean off the energy source.
However, this sentiment is anything but universal—in many other regions of the world, nuclear power is still ramping up, and it’s expected to be a key energy source for decades to come.
Using data from the Power Reactor Information System, maintained by the International Atomic Energy Agency, the map above gives a comprehensive look at where nuclear reactors are subsiding, and where future capacity will reside.
Increasing Global Nuclear Use
Despite a dip in total capacity and active reactors last year, nuclear power still generated around 10% of the world’s electricity in 2019.
Part of the increased capacity came as Japan restarted some plants and European countries looked to replace aging reactors. But most of the growth is driven by new reactors coming online in Asia and the Middle East.
China is soon to have more than 50 nuclear reactors, while India is set to become a top-ten producer once construction on new reactors is complete.
Decreasing Use in Western Europe and North America
The slight downtrend from 450 operating reactors in 2018 to 443 in 2019 was the result of continued shutdowns in Europe and North America. Home to the majority of the world’s reactors, the two continents also have the oldest reactors, with many being retired.
At the same time, European countries are leading the charge in reducing dependency on the energy source. Germany has pledged to close all nuclear plants by 2022, and Italy has already become the first country to completely shut down their plants.
Despite leading in shutdowns, Europe still emerges as the most nuclear-reliant region for a majority of electricity production and consumption.
In addition, some countries are starting to reassess nuclear energy as a means of fighting climate change. Reactors don’t produce greenhouse gases during operation, and are more efficient (and safer) than wind and solar per unit of electricity.
Facing steep emission reduction requirements, a variety of countries are looking to expand nuclear capacity or to begin planning for their first reactors.
A New Generation of Nuclear Reactors?
For those parties interested in the benefits of nuclear power, past accidents have also led towards a push for innovation in the field. That includes studies of miniature nuclear reactors that are easier to manage, as well as full-size reactors with robust redundancy measures that won’t physically melt down.
Additionally, some reactors are being designed with the intention of utilizing accumulated nuclear waste—a byproduct of nuclear energy and weapon production that often had to be stored indefinitely—as a fuel source.
With some regions aiming to reduce reliance on nuclear power, and others starting to embrace it, the landscape is certain to change.
