With bike weddings, bike parades, hundreds of naked bicyclists, bike fashion shows, popular & interesting cargo bikes, and travelling bike pubs, Portland is #3 on this great bicycle city photo tours list.

Portland has great bicycle facilities (colored bike lanes, bike boxes at intersections, great bike signs, off-road bicycle paths, etc.), a large number of people using the bicycle for transportation, and a bike culture that brings the fun of bicycling to another level.

As a result of these factors and more, Portland was the first large city in the US to achieve the Platinum level Bike Friendly award from the League of American Bicyclists (LAB) — the Platinum level being the highest level possible (above Gold, Silver and Bronze). It is truly a world-class bicycle city now, and the amazing photos in this photo tour help to show that.

One thing many Americans have been loathe to accept is public transportation. Perhaps it is a feeling embodied in the quote attributed to Homer Simpson that “public transportation is for jerks and lesbians.” Or maybe it’s the fact that America is huge and far too spread out to make public transportation viable for many commuters. Yet even so, public transportation remains one of the smartest choices for much of the US, and, with the green revolution must come greater acceptance of it.

And, when you’re talking public transit, buses make up one of the most important parts, but they are gas guzzlers. So naturally, weening these behemoths off of petrol is a high priority for many city governments. Towards this end, China and Sinautec have been testing a fleet of electric buses equipped with ultracapacitors for quick recharging and zero emissions… and so far it works.

Of course, there is a catch.

RET’s basic technology is this: they have a retrofitable hydraulic propulsion system for large vehicles that stores energy in hydraulic cylinders with compressed gas. The vehicle, such as a city bus, then uses that stored energy to give it a boost when starting up. The technology is known as RPS, or Retrofitable Propulsion System, and reduces fuel use by 25 percent and emissions by 25 percent. But before you finish mumbling about how improved fuel economy doesn’t eliminate our dependence on fossil-fuel based energy, this system can improve the fuel and emissions of vehicles using all forms of fuel including ethanol, biodiesel, compressed natural gas, propane and more.

“We like to say that the vehicle is indifferent and fuel agnostic,” said Sam Jones, President of Recaptured Energy Technologies.

London Mayor Boris Johnson has announced plans to create Britain’s first “hydrogen highway” by building a network of hydrogen filling stations throughout the capital.

As part of the scheme, a pilot fleet of around 150 hydrogen cars, five buses and 20 black taxis will be assembled in the run-up to the 2012 London Olympics.

The flamboyant mayor has gone on record as saying that he wants Britain to become a world leader in fuel cell technology and his team have made the ambitious claim that, within twenty years, up to one in three of the 31m cars in Britain could be fuelled by hydrogen.

Recently, I came up with a list of seven things that really stand out to me as good environmental practices in Europe that could be transferred to the US. These could all be adopted in the US, but some are more personal in nature and some are more systematic. Furthermore, some of the personal ones regard large, life decisions, and some are much simpler in nature and easier to implement into your life now.

Of course, Europe is not one country and things vary from country to country. Nonetheless, there are also several similarities across borders. I have friends in other countries and have traveled a bit as well, so I hope to be sharing the best of the best.

Here’s the list!

Washington, DC’s Metro system recently enacted a random police search policy for its riders, citing increased security concerns for the decision. But in reality, the new policy does nothing to protect people from terrorist attacks and pushes people away from public transit and into cars.

Which is the bigger threat: a terrorist attack on a train or the greenhouse gases that spew from cars stuck in rush hour traffic?

The high cost of gas has pushed retail gas purchases down 2 to 3 percent. What are people doing instead? Taking public transportation!

The first quarter report from the American Public Transportation Association (APTA) found that use of public transportation is skyrocketing in tandem with gas prices. Last year 10.3 billion trips were taken on U.S. public transportation — the highest in 50 years. Ridership on streetcars, trolleys, commuter rails, subways, and buses are all up. Even Amtrak ridership is soaring.

This shift presents an historic opportunity.

It was hard to get us Americans out of our cars when gas was cheap, but now we’re trying public transportation in record numbers. And once people try it, odds are they’ll prefer it, which is great news for the environment.

Good public transportation is more pleasant than a private car (you can’t read while you’re driving), and far cheaper. A calculator on the APTA Web site shows how much you can save by leaving your car parked at home.
