Episode 116: Will automated vehicles help save energy?

Automated vehicles can be safer and make life more efficient than conventional vehicles, but all of that affects energy use. Energy expert Jeremy Michalek, professor at Carnegie Mellon University and Director of the Vehicle Electrification Group, tells us how it works.

HOST: Will automated vehicles help save energy? On this week’s Energy Bite, Jeremy Michalek, a professor at Carnegie Mellon University, has some answers.
MICHALEK: Some of today’s vehicles already offer early levels of automation, such as adaptive cruise control or lane-centering. When vehicles are automated, they may cause fewer accidents and less congestion, while improving driving efficiency, so energy use could be significantly reduced.
HOST: What about fully autonomous self-driving vehicles?
MICHALEK: With fully autonomous vehicles it’s anybody’s guess. For example, safe 1-seater driverless taxis could revolutionize the commute, enable cities to pack more vehicles per lane, and eliminate the need for a parking lot in front of every business.
But they could also encourage people to live farther from work, spend a large portion of their day in transit, and they could increase travel demand from groups like children or those with disabilities.
Given these massive potential changes, it’s too early to know whether autonomous vehicles will use more or less energy.
