Zero-emissions are given off during operation, allowing you to go indoors with your Segway PT. It does draw electric power during recharge, but that electricity causes fourteen times less greenhouse gas emissions (PDF) than driving a car. After one year on your Segway PT you would have literally saved a ton of CO2 from being released into the atmosphere. (in fact it’s probably more than that, a ton is based on average MPG, while most short distance driving results in much lower mileage.)
Segway Eco Friendly as compared to the average American car.
When used for a regular commute1, a Segway PT is 11 times more energy-efficient than the average American car2. Consider these differences in operating cost and carbon footprint:
2 Assumes realization of average efficiency. When car is first started and driven only for short distances, actual efficiency is typically poorer.
