Animation: How Wind Turbines Work
The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects.
By the end of the 19th century, wind energy took on a whole new meaning as engineers in Scotland, Denmark, and the United States invented the first wind turbines that generated electricity. Many technological improvements have been made since, and now modern wind farms dot the landscapes of countries around the world.

Today, wind power is an important element of the green energy mix, and its estimated that 432 GW of wind farms are installed globally. In the United States, nearly 5% of all power is now generated by wind.
How Wind Turbines Work
How do these massive propellers get into motion? Once they are turning, what do they do?
As shown in the animation, it’s all about the lift and drag forces created by the shape of the blades. Lift acts perpendicular to the direction of wind flow and drag acts parallel to the direction of wind flow.
The blades are designed so that when wind passes, a low-pressure pocket of air is created by faster moving wind on the curved side of the blade. This sucks the blade in the downwind direction, creating lift. The blades are then connected to a series of shafts that spin an electromagnetic induction generator, and this creates electricity.
There are some other bells and whistles that help to maximize efficiency in a modern wind turbine as well.
The anemometer measures wind speed, while the controller starts and stops the turbines to operate only at desirable wind speeds (between 8 and 55 kmph). The wind vane measures the wind’s direction and communicates this information to the yaw drive, which helps make adjustments to the turbine’s orientation. Lastly, there is also a braking system installed which can be used for emergency stops when wind speeds get too extreme.

Mapped: Renewable Energy and Battery Installations in the U.S. in 2023
This graphic describes new U.S. renewable energy installations by state along with nameplate capacity, planned to come online in 2023.

Renewable and Battery Installations in the U.S. in 2023

Renewable energy, in particular solar power, is set to shine in 2023. This year, the U.S. plans to get over 80% of its new energy installations from sources like battery, solar, and wind.
The above map uses data from EIA to highlight planned U.S. renewable energy and battery storage installations by state for 2023.
Texas and California Leading in Renewable Energy
Nearly every state in the U.S. has plans to produce new clean energy in 2023, but it’s not a surprise to see the two most populous states in the lead of the pack.
Even though the majority of its power comes from natural gas, Texas currently leads the U.S. in planned renewable energy installations. The state also has plans to power nearly 900,000 homes using new wind energy.
California is second, which could be partially attributable to the passing of Title 24, an energy code that makes it compulsory for new buildings to have the equipment necessary to allow the easy installation of solar panels, battery storage, and EV charging.
New solar power in the U.S. isn’t just coming from places like Texas and California. In 2023, Ohio will add 1,917 MW of new nameplate solar capacity, with Nevada and Colorado not far behind.
Top 10 States | Battery (MW) | Solar (MW) | Wind (MW) | Total (MW) |
---|---|---|---|---|
Texas | 1,981 | 6,462 | 1,941 | 10,385 |
California | 4,555 | 4,293 | 123 | 8,970 |
Nevada | 678 | 1,596 | 0 | 2,274 |
Ohio | 12 | 1,917 | 5 | 1,934 |
Colorado | 230 | 1,187 | 200 | 1,617 |
New York | 58 | 509 | 559 | 1,125 |
Wisconsin | 4 | 939 | 92 | 1,034 |
Florida | 3 | 978 | 0 | 980 |
Kansas | 0 | 0 | 843 | 843 |
Illinois | 0 | 363 | 477 | 840 |
The state of New York is also looking to become one of the nation’s leading renewable energy providers. The New York State Energy Research & Development Authority (NYSERDA) is making real strides towards this objective with 11% of the nation’s new wind power projects expected to come online in 2023.
According to the data, New Hampshire is the only state in the U.S. that has no new utility-scale renewable energy installations planned for 2023. However, the state does have plans for a massive hydroelectric plant that should come online in 2024.
Decarbonizing Energy
Renewable energy is considered essential to reduce global warming and CO2 emissions.
In line with the efforts by each state to build new renewable installations, the Biden administration has set a goal of achieving a carbon pollution-free power sector by 2035 and a net zero emissions economy by no later than 2050.
The EIA forecasts the share of U.S. electricity generation from renewable sources rising from 22% in 2022 to 23% in 2023 and to 26% in 2024.
