Name one environmental benefit of using electric outdoor power equipment.

Using electric outdoor power equipment significantly reduces emissions, which is a key environmental benefit. Unlike gasoline-powered tools, electric equipment does not produce exhaust fumes that contribute to air pollution and greenhouse gas emissions. This reduction in emissions helps mitigate climate change and improves air quality, making electric tools a more environmentally friendly choice for outdoor power tasks.

The other options relate to practical aspects of using equipment but do not directly address environmental impacts. For instance, while lower cost of operation is a financial benefit, it doesn't reflect environmental considerations. Increased power and greater mobility may pertain to performance factors but do not impact the ecological footprint of the equipment. Therefore, reduced emissions stands out as the primary environmental advantage of switching to electric outdoor power equipment.
