A Bay Area Experiment in Electric Bike Sharing

In this post for The New York Times Green blog, I reported on a federally financed electric bike share program quietly coming together in the San Francisco Bay Area.

Rather than zigging and zagging to avoid steep inclines, e-bike users will be able to pedal up and over with help from an electric motor. For those hauling cargo, electric bicycle trailers will be available for hourly rentals, too.

City CarShare, a local nonprofit car sharing provider, is heading up the project, while the Transportation Sustainability Research Center at the University of California, Berkeley is responsible for assessing the impact and lessons learned.

City CarShare chief executive Rick Hutchinson told me about the nuts and bolts of the project, and the grand vision, too. “People will go to our site, pull down a list, and see maybe four cars and some electric bikes available for their errand or shopping trip or doctor’s appointment” The bikes will be cheaper than the cars. Seeing these options side by side, Mr. Hutchinson said, people who may not have considered biking before may ask themselves, “Could I do this on a bike?”

Green Moves: Medellin Cable Cars, San Francisco Parking Reform

Two cities renowned for the cable cars that traverse their hilly terrains—San Francisco, California, and Medellin, Colombia—captured this year’s Sustainable Transport Award from the Institute for Transportation and Development Policy (ITDP).

Reporting on the award for National Geographic Digital Media, I learned that Medellin’s system is one of very few aerial cable car systems used for mass transit, and the first of its kind in Latin America. Operating since 2006, it provides a crucial link to city life and work for residents of poor barrios high above the city center in the Aburra Valley.

San Francisco, meanwhile, made its mark in 2011 in parking reform, according to ITDP. The city not only introduced pricing schemes that vary based on time of day and real-time availability, but also traded some parking spots for public space, or “parklets,” as part of its “Pavement to Parks” program.

Review Roundup: Car-Sharing Services

It’s never been easier to be carless in the city. Not because of a boom in public transit, but because of car-sharing services, which make owning a vehicle akin to paying for a nanny instead of hiring the occasional babysitter.

So begins my review of four car-sharing services for Wired Magazine (October 2011). I tested Zipcar and the non-profit City CarShare, plus two P2P services, RelayRides and Getaround, on the streets of San Francisco. I checked out their insurance policies, mobile apps, application processes, websites, prices, availability, and more. For the full rundown and scores, head on over to Wired.

2 Fisheries Collapsed Unnoticed, Study Says

Two popular Southern California fisheries have collapsed right under the noses of management agencies that had inadequate data, a new study suggests. In an article in the Canadian Journal of Fisheries and Aquatic Sciences, the authors say the population of barred sand bass and kelp bass began to shrink in the early 1980s amid regional changes in ocean conditions, including warmer temperatures.

But as I’ve reported in a post for The New York Times Green blog, a combination of environmental factors and fishing in seasonal spawning areas appears to have “pushed the species over the edge.” Read the full story here.

RelayRides Gets a Lift from G.M.’s OnStar

General Motors and RelayRides, a peer-to-peer car-sharing service that allows private car owners to rent their vehicles, announced a partnership and possible investment this week. Under an exclusive two-year agreement, RelayRides users will be able to unlock G.M. vehicles that are registered with the car-sharing service and subscribed to OnStar, the automaker’s communication service, with a mobile phone app. In this post for The New York Times Wheels blog, I explain the deal and why some people see the growing amount of computing power in cars as a “natural fit” for car sharing.

Smarter Trucking Saves Fuel Over the Long Haul

In my latest story for National Geographic Digital Media, I report how trucking companies are looking to boost fuel economy by improving driver behavior, and using on-board technology to monitor and control what goes on behind the wheel.

Just over 33 years ago, 33 truckers competed for three days in a fuel economy contest dubbed the “Double Nickel Challenge.” Named after radio slang for the 55 miles per hour speed limit then in force in the United States, the goal was simple: to test the claim, common among truckers at the time, that big rigs got better mileage at higher speeds.

Long-haul truckers from all over the United States gathered in East Liberty, Ohio, to watch as drivers navigated laps around a track-first at 55 mph, and then at any speed of their choosing. With a few exceptions, they burned less fuel in the first, speed-limited, trial.

More than three decades later, the double-nickel U.S. speed limit-enacted in the wake of the 1973 Arab oil embargo-has faded into history on most highways. But so has credibility for the claim that higher truck speeds beget better fuel economy.

Trading Oil for Natural Gas in the Truck Lane

Why would a company buy thousands of trucks and vans fresh off the assembly line and install a bulky and expensive new fuel system? As I report in my latest piece for National Geographic, it comes down to the bottom line.

In a time when natural gas is relatively cheap, but manufacturers build mostly gasoline and diesel models, companies like AT&T and Verizon have calculated it’s worth the expense to convert some gasoline vehicles to burn compressed natural gas. Read the full article here.
