Line graph titled Rotor Diameters of Newly Installed Wind Turbines in the United States, 2011–2021. The horizontal axis is labeled Year. It ranges from 2011 to 2021 in increments of 1. The vertical axis is labeled Percent of newly installed turbines. It ranges from 0 to 90 in increments of 10.

The following 4 lines are shown:

- Greater than 130 meters
- Less than 100 meters
- 100–115 meters
- 115–130 meters

All other things being equal, the larger a wind turbine’s rotor diameter (the diameter of the imaginary circle swept by the turbine’s rotating blades), the greater amount of energy the turbine can generate. In a research paper on wind power, a student claims that in the United States, the amount of energy generated per newly installed turbine increased substantially between 2011 and 2021.
Which choice best describes data in the graph that support the student’s claim?
