Visualizing the World’s Largest Hydroelectric Dams
Visualizing the World’s Largest Hydroelectric Dams
Did you know that hydroelectricity is the world’s biggest source of renewable energy? According to recent figures from the International Renewable Energy Agency (IRENA), it represents 40% of total capacity, ahead of solar (28%) and wind (27%).
This type of energy is generated by hydroelectric power stations, which are essentially large dams that use the water flow to spin a turbine. They can also serve secondary functions such as flow monitoring and flood control.
To help you learn more about hydropower, we’ve visualized the five largest hydroelectric dams in the world, ranked by their maximum output.
Overview of the Data
The following table lists key information about the five dams shown in this graphic, as of 2021. Installed capacity is the maximum amount of power that a plant can generate under full load.
Country | Dam | River | Installed Capacity (gigawatts) | Dimensions (meters) |
---|---|---|---|---|
🇨🇳 China | Three Gorges Dam | Yangtze River | 22.5 | 181 x 2,335 |
🇧🇷 Brazil / 🇵🇾 Paraguay | Itaipu Dam | Parana River | 14.0 | 196 x 7,919 |
🇨🇳 China | Xiluodu Dam | Jinsha River | 13.9 | 286 x 700 |
🇧🇷 Brazil | Belo Monte Dam | Xingu River | 11.2 | 90 X 3,545 |
🇻🇪 Venezuela | Guri Dam | Caroni River | 10.2 | 162 x 7,426 |
At the top of the list is China’s Three Gorges Dam, which opened in 2003. It has an installed capacity of 22.5 gigawatts (GW), which is close to double the second-place Itaipu Dam.
In terms of annual output, the Itaipu Dam actually produces about the same amount of electricity. This is because the Parana River has a low seasonal variance, meaning the flow rate changes very little throughout the year. On the other hand, the Yangtze River has a significant drop in flow for several months of the year.
For a point of comparison, here is the installed capacity of the world’s three largest solar power plants, also as of 2021:
- Bhadla Solar Park, India: 2.2 GW
- Hainan Solar Park, China: 2.2 GW
- Pavagada Solar Park, India: 2.1 GW
Compared to our largest dams, solar plants have a much lower installed capacity. However, in terms of cost (cents per kilowatt-hour), the two are actually quite even.
Closer Look: Three Gorges Dam
The Three Gorges Dam is an engineering marvel, costing over $32 billion to construct. To wrap your head around its massive scale, consider the following facts:
- The Three Gorges Reservoir (which feeds the dam) contains 39 trillion kg of water (42 billion tons)
- In terms of area, the reservoir spans 400 square miles (1,045 square km)
- The mass of this reservoir is large enough to slow the Earth’s rotation by 0.06 microseconds
Of course, any man-made structure this large is bound to have a profound impact on the environment. In a 2010 study, it was found that the dam has triggered over 3,000 earthquakes and landslides since 2003.
The Consequences of Hydroelectric Dams
While hydropower can be cost-effective, there are some legitimate concerns about its long-term sustainability.
For starters, hydroelectric dams require large upstream reservoirs to ensure a consistent supply of water. Flooding new areas of land can disrupt wildlife, degrade water quality, and even cause natural disasters like earthquakes.
Dams can also disrupt the natural flow of rivers. Other studies have found that millions of people living downstream from large dams suffer from food insecurity and flooding.
Whereas the benefits have generally been delivered to urban centers or industrial-scale agricultural developments, river-dependent populations located downstream of dams have experienced a difficult upheaval of their livelihoods.
– Richter, B.D. et al. (2010)
Perhaps the greatest risk to hydropower is climate change itself. For example, due to the rising frequency of droughts, hydroelectric dams in places like California are becoming significantly less economical.

White Gold: Mapping U.S. Lithium Mines
In this graphic, Visual Capitalist partnerered with EnergyX to explore the size and location of U.S. lithium mines.
White Gold: Mapping U.S. Lithium Mines
The U.S. doubled imports of lithium-ion batteries for the third consecutive year in 2022, and with EV demand growing yearly, U.S. lithium mines must ramp up production or rely on other nations for their supply of refined lithium.
To determine if the domestic U.S. lithium opportunity can meet demand, we partnered with EnergyX to determine how much lithium sits within U.S. borders.
U.S. Lithium Projects
The most crucial measure of a lithium mine’s potential is the quantity that can be extracted from the source.
For each lithium resource, the potential volume of lithium carbonate equivalent (LCE) was calculated with a ratio of one metric ton of lithium producing 5.32 metric tons of LCE. Cumulatively, existing U.S. lithium projects contain 94.8 million metric tons of LCE.
Rank | Project Name | LCE, million metric tons (est.) |
---|---|---|
1 | McDermitt Caldera | 21.5 |
2 | Thacker Pass | 19.1 |
3 | Tonopah Flats | 18.0 |
4 | TLC Lithium | 10.7 |
5 | Clayton Valley (Century Lithium) | 6.3 |
6 | Zeus Lithium | 6.3 |
7 | Rhyolite Ridge | 3.4 |
8 | Arkansas Smackover (Phase 1A) | 2.8 |
9 | Basin Project | 2.2 |
10 | McGee Deposit | 2.1 |
11 | Arkansas Smackover (South West) | 1.8 |
12 | Clayton Valley (Lithium-X, Pure Energy) | 0.8 |
13 | Big Sandy | 0.3 |
14 | Imperial Valley/Salton Sea | 0.3 |
U.S. Lithium Opportunities, By State
U.S. lithium projects mainly exist in western states, with comparatively minor opportunities in central or eastern states.
State | LCE, million metric tons (est.) |
---|---|
Nevada | 88.2 |
Arkansas | 4.6 |
Arizona | 2.5 |
California | 0.3 |
Currently, the U.S. is sitting on a wealth of lithium that it is underutilizing. For context, in 2022, the U.S. only produced about 5,000 metric tons of LCE and imported a projected 19,000 metric tons of LCE, showing that the demand for the mineral is healthy.
The Next Gold Rush?
U.S. lithium companies have the opportunity to become global leaders in lithium production and accelerate the transition to sustainable energy sources. This is particularly important as the demand for lithium is increasing every year.

Will Direct Lithium Extraction Disrupt the $90B Lithium Market?
Visual Capitalist and EnergyX explore how direct lithium extraction could disrupt the $90B lithium industry.
Will Direct Lithium Extraction Disrupt the $90B Lithium Market?
Current lithium extraction and refinement methods are outdated, often harmful to the environment, and ultimately inefficient. So much so that by 2030, lithium demand will outstrip supply by a projected 1.42 million metric tons. But there is a solution: Direct lithium extraction (DLE).
For this graphic, we partnered with EnergyX to try to understand how DLE could help meet global lithium demands and change an industry that is critical to the clean energy transition.
The Lithium Problem
Lithium is crucial to many renewable energy technologies because it is this element that allows EV batteries to react. In fact, it’s so important that projections show the lithium industry growing from $22.2B in 2023 to nearly $90B by 2030.
But even with this incredible growth, as you can see from the table, refined lithium production will need to increase 86.5% over and above current projections.
2022 (million metric tons) | 2030P (million metric tons) | |
---|---|---|
Lithium Carbonate Demand | 0.46 | 1.21 |
Lithium Hydroxide Demand | 0.18 | 1.54 |
Lithium Metal Demand | 0 | 0.22 |
Lithium Mineral Demand | 0.07 | 0.09 |
Total Demand | 0.71 | 3.06 |
Total Supply | 0.75 | 1.64 |
The Solution: Direct Lithium Extraction
DLE is a process that uses a combination of solvent extraction, membranes, or adsorbents to extract and then refine lithium directly from its source. LiTASTM, the proprietary DLE technology developed by EnergyX, can recover an incredible 300% more lithium per ton than existing processes, making it the perfect tool to help meet lithium demands.
Additionally, LiTASTM can refine lithium at the lowest cost per unit volume directly from brine, an essential step in meeting tomorrow’s lithium demand and manufacturing next-generation batteries, while significantly reducing the footprint left by lithium mining.
