Cities across the U.S. are increasingly enacting bans on gasoline-powered landscaping equipment and promoting electric alternatives, driven by concerns over noise pollution and environmental impact. These shifts aim to create quieter neighborhoods and reduce the exposure of landscaping professionals to harmful emissions and vibrations.
The transition to electric landscaping tools offers several advantages. Beyond reducing noise, which can extend working hours by allowing operation at times when residents demand quiet, these tools also decrease carbon emissions. For landscapers, the reduction in vibrations and exposure to pollutants presents a healthier work environment.
Organizations like the American Green Zone Alliance (AGZA) are supporting this transition by providing training for landscapers. Participants in AGZA training have reported that electric leaf blowers, for instance, are comparable in weight to traditional backpacks and produce a less intrusive, higher-pitched buzz compared to the loud roar of gasoline engines.
The growing demand for electric landscaping equipment is attracting new manufacturers to the sector. Whisper Aero, a U.S. aerospace startup primarily focused on electric propulsion systems for aircraft, has pivoted to consumer technology. The company realized in 2022 that its advanced aerospace fans could be effectively adapted for leaf blowers, particularly following increased public sensitivity to noise during the COVID-19 pandemic.
Andrew Terajewicz, Whisper Aero's director of air management, stated that the company's technology is "cleaner, quieter and more efficient than other air-moving technologies that exist today." He highlighted the leaf blower as an ideal application for their innovation. The battery on Whisper Aero's leaf blower can operate for up to 50 minutes at full power. The company has been scaling up manufacturing to meet consumer demand for its products.
Online pre-orders for Whisper Aero's handheld leaf blower began this year. The product is positioned at the higher end of the electric leaf blower market, which generally features higher price points than their gasoline-powered counterparts. However, consumers are offered a quieter, more efficient alternative. Dan Mabe, founder of AGZA, described the technology as "so ultra quiet yet powerful, that the brain has a hard time understanding what's happening."
Whisper Aero plans to further develop its product line, including a backpack leaf blower designed specifically for professional landscapers. The broader adoption of electric landscaping equipment is progressing, though the pace of this transition varies among municipalities and professional operations.
