Note: Updated to reflect 2017 numbers
The Washington Post has put together an extraordinary data visualization that shows how the United States has generated its electricity so far this year. Using data from the Energy Information Administration, they have mapped every power source and categorized it by type and size.

I will recap the most interesting parts of their project here, but we highly recommend that you visit their online interactive version of this visualization to get the most out of their work.
Plant Capacity by Megawatt
This above visualization is a little overwhelming, as it includes every power source in America. However, later on we will show various visualizations by power type, which make it easier to make sense of.
Power Generated by Source: Coal
Data visualized like this shows there is still a large reliance on specific energy types such as coal, hydro, and nuclear. For example, in 2017, 27 states still rely on coal to produce at least 25% of their electricity.
Meanwhile, the following chart on solar shows how far photovoltaics still have to go to make a significant impact in the overall energy mix.
Power Generated by Source: Solar
While community solar farms are starting to take off in the United States, solar technology as a whole still does not provide substantial amounts of electricity. It is clear that California is the leader in solar capacity, but it actually only accounts for 10% of total electricity generation in the state.
Coal Power Map
The United States has 400 coal-fired power plants that generate 30% of the nation’s electricity. Coal produces the majority of energy in 13 sates, but thanks to America’s Clean Power Plan, a whopping 111 plants have been shut down since 2015.
Natural Gas Power Map
The United States has 1,793 natural gas power plants that generate 34% of the nation’s electricity. Natural gas is the primary source of power in 19 states.
Nuclear Power Map
The United States has 61 nuclear reactors that generate 20% of the nation’s electricity. 20 states get no power from nuclear at all.
Hydro Power Map
The United States has 1,444 hydroelectric dams that generate 7% of the nation’s electricity. The Grand Coulee Dam in Washington State has 6,809 MW of installed capacity, making it the largest contributor in nameplate capacity in the country. (However, as Forbes notes, actual electricity generated depends on capacity factor.)
Wind Power Map
The United States has 999 wind power plants that generate 6% of the nation’s electricity. The best source for wind is in the Great Plains, where it blows very reliably. Around 2010, China leapfrogged the USA with parabolic wind power growth.
Solar Power Map
The United States has 1,721 solar power plants that generate 1% of the nation’s electricity.
Oil Power Map
The United States has 1,076 oil-fired power plants that generate less than 1% of the nation’s electricity. America is shaking off its addiction to oil and no longer relies on it for generating electricity because of price swings. Hawaii is the only state to get the majority of its energy from oil.
Map: The Countries With the Most Oil Reserves
See the countries with the most oil reserves on this map, which resizes each country based on how many barrels of oil are contained in its borders.
Map: The Countries With the Most Oil Reserves
There’s little doubt that renewable energy sources will play a strategic role in powering the global economy of the future.
But for now, crude oil is still the undisputed heavyweight champion of the energy world.
In 2018, we consumed more oil than any prior year in history – about 99.3 million barrels per day on a global basis. This number is projected to rise again in 2019 to 100.8 million barrels per day.
The Most Oil Reserves by Country
Given that oil will continue to be dominant in the energy mix for the short and medium term, which countries hold the most oil reserves?
Today’s map comes from HowMuch.net and it uses data from the CIA World Factbook to resize countries based on the amount of oil reserves they hold.
Here’s the data for the top 15 countries below:
|Rank||Country||Oil Reserves (Barrels)|
|#1||🇻🇪 Venezuela||300.9 billion|
|#2||🇸🇦 Saudi Arabia||266.5 billion|
|#3||🇨🇦 Canada||169.7 billion|
|#4||🇮🇷 Iran||158.4 billion|
|#5||🇮🇶 Iraq||142.5 billion|
|#6||🇰🇼 Kuwait||101.5 billion|
|#7||🇦🇪 United Arab Emirates||97.8 billion|
|#8||🇷🇺 Russia||80.0 billion|
|#9||🇱🇾 Libya||48.4 billion|
|#10||🇳🇬 Nigeria||37.1 billion|
|#11||🇺🇸 United States||36.5 billion|
|#12||🇰🇿 Kazakhstan||30.0 billion|
|#13||🇨🇳 China||25.6 billion|
|#14||🇶🇦 Qatar||25.2 billion|
|#15||🇧🇷 Brazil||12.7 billion|
Venezuela tops the list with 300.9 billion barrels of oil in reserve – but even this vast wealth in natural resources has not been enough to save the country from its recent economic and humanitarian crisis.
Saudi Arabia, a country known for its oil dominance, takes the #2 spot with 266.5 billion barrels of oil. Meanwhile, Canada and the U.S. are found at the #3 (169.7 billion bbls) and the #11 (36.5 billion bbls) spots respectively.
The Cost of Production
While having an endowment of billions of barrels of oil within your borders can be a strategic gift from mother nature, it’s worth mentioning that reserves are just one factor in assessing the potential value of this crucial resource.
In Saudi Arabia, for example, the production cost of oil is roughly $3.00 per barrel, which makes black gold strategic to produce at almost any possible price.
Other countries are not so lucky:
|Country||Production cost (bbl)||Total cost (bbl)*|
|🇬🇧 United Kingdom||$17.36||$44.33|
|🇺🇸 U.S. shale||$5.85||$23.35|
|🇺🇸 U.S. non-shale||$5.15||$20.99|
|🇸🇦 Saudi Arabia||$3.00||$8.98|
Even if a country is blessed with some of the most oil reserves in the world, it may not be able to produce and sell that oil to maximize the potential benefit.
Countries like Canada and Venezuela are hindered by geology – in these places, the majority of oil is extra heavy crude or bitumen (oil sands), and these types of oil are simply more difficult and costly to extract.
In other places, obstacles are are self-imposed. In some countries, like Brazil and the U.S., there are higher taxes on oil production, which raises the total cost per barrel.
Mapped: Every Power Plant in the United States
What sources of power are closest to you, and how has this mix changed over the last 10 years? See every power plant in the U.S. on this handy map.
This Map Shows Every Power Plant in the United States
Every year, the United States generates 4,000 million MWh of electricity from utility-scale sources.
While the majority comes from fossil fuels like natural gas (32.1%) and coal (29.9%), there are also many other minor sources that feed into the grid, ranging from biomass to geothermal.
Do you know where your electricity comes from?
The Big Picture View
Today’s series of maps come from Weber State University, and they use information from the EPA’s eGRID databases to show every utility-scale power plant in the country.
Use the white slider in the middle below to see how things have changed between 2007 and 2016:
The biggest difference between the two maps is the reduced role of coal, which is no longer the most dominant energy source in the country. You can also see many smaller-scale wind and solar dots appear throughout the appropriate regions.
Here’s a similar look at how the energy mix has changed in the United States over the last 70 years:
Up until the 21st century, power almost always came from fossil fuels, nuclear, or hydro sources. More recently, we can see different streams of renewables making a dent in the mix.
Maps by Source
Now let’s look at how these maps look by individual sources to see regional differences more clearly.
Here’s the map only showing fossil fuels.
The two most prominent sources are coal (black) and natural gas (orange), and they combine to make up about 60% of total annual net generation.
Now here’s just nuclear on the map:
Nuclear is pretty uncommon on the western half of the country, but on the Eastern Seaboard and in the Midwest, it is a major power source. All in all, it makes up about 20% of the annual net generation mix.
Finally, a look at renewable energy:
Hydro (dark blue), wind (light blue), solar (yellow), biomass (brown), and geothermal (green) all appear here.
Aside from a few massive hydro installations – such as the Grand Coulee Dam in Washington State (19 million MWh per year) – most renewable installations are on a smaller scale.
Generally speaking, renewable sources are also more dependent on geography. You can’t put geothermal in an area where there is no thermal energy in the ground, or wind where there is mostly calm weather. For this reason, the dispersion of green sources around the country is also quite interesting to look at.
