Mapped: Average Wind Speed Across the U.S.
Wind energy is a hot topic in North America and around the world as a decarbonization tool, but full utilization requires a lot of wind.
This graphic from the team at the Woodwell Climate Research Center maps the average wind speed of the continental U.S. based on NOAA data from 2021.
Zooming in, you can examine North America’s wind regions and patterns in great detail. Clearly visible is the concentration of high wind speeds in the Great Plains (known as the Prairies in Canada), which has the greatest potential for wind power. You can also follow westerly winds traveling through the North American Cordillera of mountains, including the Rocky Mountains and Cascades.
Meanwhile, the Eastern U.S. and Canada have significantly lower average wind speeds, especially in the American South. That’s despite hurricanes with extremely high winds occasionally moving northward along the Eastern Seaboard towards the North Atlantic.

As the global energy transition accelerates, battery demand continues to soar—along with competition between battery chemistries.
According to the International Energy Agency, in 2024, electric vehicle sales rose by 25% to 17 million, pushing annual battery demand past 1 terawatt-hour (TWh)—a historic milestone.
This graphic, using exclusive data from Benchmark Mineral Intelligence (as of February 2025), compares battery capacity by cathode type across major countries. It focuses on the two dominant chemistries: Nickel Cobalt Manganese (NCM) and Lithium Iron Phosphate (LFP).
Understanding Cathode Chemistries
Batteries store and release energy through the movement of lithium ions. The cathode—a key electrode—determines a battery’s cost, range, and thermal performance.
NCM
- Offers higher energy density and better performance in cold climates, but is more expensive and has a shorter lifespan.
LFP
- Known for its lower cost and improved thermal stability, though it delivers a shorter driving range and adds weight.
As of now, LFP cathodes make up 40% of the EV market in terms of gigawatt-hours (GWh).
Beyond passenger vehicles, LFP batteries are widely used in systems that undergo frequent charging and discharging—like residential and grid-scale energy storage—where added weight isn’t a major concern. They’re also ideal for daily-use applications such as buses and delivery fleets.
Regional Market Trends
In China, LFP is already dominant, accounting for 64% of the market in 2024. By 2030, that figure is projected to grow to 76%, driven by a focus on affordability in the world’s largest EV market. Notably, over 70% of all EV batteries ever manufactured have been produced in China, contributing to deep manufacturing expertise.
Region/Country | Year | % NCM | % LFP | % Other |
---|---|---|---|---|
China | 2024 | 27% | 64% | 8% |
North America | 2024 | 71% | 7% | 22% |
Europe | 2024 | 69% | 8% | 24% |
South Korea | 2024 | 62% | 4% | 35% |
Japan | 2024 | 58% | 0% | 42% |
Outside of China, NCM remains the leading chemistry due to consumer demand for longer range and premium performance.
North America – NCM holds a 71% share in 2024, with a slight decline to 69% forecasted for 2030.
Europe – NCM’s share is expected to grow from 69% in 2024 to 71% by 2030.
South Korea and Japan – Both countries show similar trends, with NCM gaining share as LFP remains limited or absent.
