The Twin Cities Metro Transit (which we voted some time ago to call "The T" but still haven't really started doing yet) has added a very cool bus to its fleet. It is Minnesota Made which is nice, and super efficient in part for reasons that I had not realized were important. From the T's web site:
- Advanced engine and hybrid technology
- Optimized onboard systems for improved efficiency
- Reduced emissions from less time spent idling
- Less idling + more efficiency = buses that run cleaner and pollute less
Unlike other buses, even some hybrids, the Xcelsior uses super efficient All Electric components, many that eliminate power-sucking hydraulic systems. Instead, itt uses an all Electric HVAC system, electric power steering rather than hydraulic and an electric air compressor to power pneumatic accessories like doors and airbrakes.

This post ties together a number of themes that I have been harping upon
for the past few years. First, from Greg Mankiw's blog:

The question of how to cut our production of carbon dioxide grows more urgent every day, and the focus tends to be on new sources of energy. Increased efficiency tends to get lost in the mix, even though it's the easiest and most readily implemented approach.
And with that ground clearance...
