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.

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.

To Curb Driving, Cities Cut Down on Car Parking

Bit by bit, for the past 40 years, the city of Copenhagen has done something revolutionary: The Danish capital has reduced its parking supply. Cutting the total number of parking spaces by a small percentage each year stands in stark contrast to the more common pattern of cities adding more and more parking to accommodate private cars.

Google Creates $280 Million Fund to Finance Solar Energy

Google is making its largest investment yet in clean energy, setting up a $280 million fund to finance home solar rooftop installations.

The search giant announced it was teaming up with the Silicon Valley’s SolarCity—a company chaired by Paypal co-founder and Tesla Motors executive Elon Musk—in an effort to break down the biggest barrier to solar energy adoption: the cost. Continue reading

Bike-Share Schemes Shift Into High Gear

Around the world, cycle-hire operators are rolling out bicycles that were tucked away for the cold and rainy months. Hundreds of new bikes and docking stations will join existing fleets, while many more cities, from Kailua to Tel Aviv to the Big Apple are joining the bike-sharing wave for the first time.

Driving the Limit: Wealthy Nations Maxed Out on Travel?

Fewer cars are projected be on the road this summer in the United States, partly because of higher gas prices — but the leveling off of road travel in several countries goes beyond yearly fluctuations. Researchers now think the world’s most developed nations might have put the brakes on travel. Or, at least, on personal travel fueled by petroleum.

In the United States, Germany, Japan, and other countries that rank among the world’s wealthiest, there are signs that driving has reached a kind of saturation point, as I’ve reported in this article for National Geographic News.

Would a New Nuclear Plant Fare Better than Fukushima?

In the weeks after the earthquake and tsunami struck Japan in early 2011, I wrote a series of stories for National Geographic Digital Media exploring three critical questions:

  • How is Japan’s Nuclear Disaster Different?
    Published March 16, 2011

    For decades, Three Mile Island and Chernobyl have served as shorthand for the nightmare of nuclear power generation gone awry. In the wake of Japan’s deadly earthquake and tsunami last week, the still-unfolding disaster of Fukushima Daiichi has come closer than any nuclear crisis in history to making it a fearsome trio. Yet key differences key differences that set the current Fukushima situation apart from the 1979 Three Mile Island emergency near Harrisburg, Pennsylvania, and the disaster in Chernobyl, Ukraine, that unfolded seven years later.

  • Would a New Nuclear Plant Fare Better than Fukushima?
    Published March 23, 2011

    Would brand-new reactors have fared better in the power outage that triggered dangerous overheating at one of Japan’s oldest power plants? The answer seems to be: Not necessarily. The vast majority of plants under construction around the world, 47 in all, are the same 1970s vintage as Fukushima Daiichi, and without integrated passive safety systems.

  • Is Armenia’s Nuclear Plant the World’s Most Dangerous?
    Published April 11, 2011 (Byline: Marianne Lavelle and Josie Garthwaite)
    In the shadow of Mount Ararat, the beloved and sorrowful national symbol of Armenia, stands a 31-year-old nuclear plant that is no less an emblem of the country’s resolve and its woe.

    The Metsamor power station is one of a mere handful of remaining nuclear reactors of its kind that were built without primary containment structures. All five of these first-generation water-moderated Soviet units are past or near their original retirement ages, but one salient fact sets Armenia’s reactor apart from the four in Russia. Metsamor lies on some of Earth’s most earthquake-prone terrain.

China’s Move Toward Greener Transit

How can more than a billion people travel to and fro, around and through some of the world’s most populous and fastest growing cities—without creating epic traffic jams, tapping imported oil or exacerbating noxious air pollution? That’s the challenge facing China as it develops a transportation system for its increasingly urban, car-buying population. Continue reading

Rev Up Your Motors, Electric Cars Zip Into View

The earliest plug-in car buyers will contend with high price tags, limited charging infrastructure, uncertainty about long-term durability and resale values, and insecurity about hitting the road without being able to refuel at just any convenient gas station.

But automakers have devised different strategies for tackling these challenges and, they hope, for winning over thousands of customers in the years ahead. For an overview of the strengths, weaknesses and cool facts about 11 electric and plug-in hybrid models from car companies large and small, check out this photo-rich piece I wrote for National Geographic Daily News.
