The Segway PT can be a major part of your organisation or city's efforts to curb the consumption of fossil fuels and creation of excess greenhouse gases. Since each Segway PT operates off of lithium-ion batteries, it's inherently zero emissions during operation. This makes it a transportation tool that can be ridden indoors. In addition, Segway Inc. has taken the extra step through its Renewable Energy Credit program to encourage the creation and use of clean energy such as solar or wind. You can learn more about the program here.
Traditional fuel vehicles are constantly emitting greenhouse gases while in use. Even if they're idling, they're still doing significant harm. For example, according to the California Energy Commission, an SUV that's idling for two minutes consumes about the same amount of fuel as it would take to go almost a kilometre. Imagine taking the officer out of that petrol guzzling vehicle and empowering him or her to interact more with passersby. That same officer could do the outdoor patrol and head inside to respond to emergencies too – often faster than in that vehicle or solely by foot.
If you're interested in the nitty-gritty about how efficient a Segway PT is, you can say that it's 11 times more efficient than the average car. How'd we get that? Read the Segway Inc. white paper on efficiency to learn all about it.
