Hawaii plans to remove numerous wind turbines after the implementation of new rules regarding where the state can build these renewable energy structures. The decision has sparked both celebration from locals and concern among officials over how this will impact the state’s clean energy transition.
Many living in Hawaii have long argued that wind energy infrastructure is too close to residential areas. Protests during the 2019 installation of turbines on O‘ahu resulted in over 100 arrests. Locals have voiced concerns about noise, shadow flicker, mechanical risks and potential health impacts, including headaches, sleep disruption and stress.
In response, the Honolulu City Council recently approved new regulations requiring turbines to be located at least 1.25 miles — or 10 times their height, whichever is greater — from residential, apartment or resort property lines. Previously, the setback was only equal to the height of the turbine.
This means turbines currently in violation of the mandate will be decommissioned once their contracts expire. The first set is on track for removal in 2031, and the remainder will likely occur by 2040.
State officials are concerned the stricter rules could hinder Hawaii’s renewable energy goals. Under state law, utility companies are required to source 100% of their electricity from clean power sources by 2045. Wind energy will likely make up 20% of that total. Right now, Hawaii derives about 6% of its energy from wind turbines.
Deputy Director Stephen Walls of the Hawaii Energy Office warned that the new setbacks might deter future wind development in the state, but expressed hopes that advancements in solar and battery storage might offset the impact.
