Public Transportation And Energy Efficiency: Bordeaux’s Sustainable Mobility Initiatives – Known to most Americans for its famous wine varieties, Bordeaux is also an innovator in surface transportation technologies that enable wireless streetcar operations on downtown streets.
On my visit to Bordeaux in 2010, I drank its fine wines, strolled along the Garonne River, enjoyed the comfortable summer climate…and considered its innovative trams (light rail/tram). Maybe “trams…really?” Yes! Although most systems are powered by overhead wires, when it opened in 2003 the Bordeaux system was the only modern example of a ground-level wireless tramway in the world. The proprietary APS system enables typical overhead cable operation in areas outside the central city and ground-level power (see photo below) internally to preserve unobstructed views of the old city. Although the system initially had reliability issues, it now seems to be working well.

During my stay I noticed that the trams run on special routes, some of which cover almost the entire street (see photo 1). This allows trams to move without interference from cars, but has the side benefit of creating largely vehicle-free and pedestrian-safe streets in the absence of trams. This provides a great walking environment and means of transport work more efficiently. Maybe some lessons we can learn from Bordeaux and implement here.

Where are the Late Night Metrobus Riders? Water saving as part of sustainability in Metro. LaTrucks and buses are the lifeblood of the transportation industry. But these fleet vehicles that transport people and goods around the world are a significant source of carbon emissions and air pollution. Over the years, we have had to accept this uncomfortable but necessary disagreement.
We are on the brink of a historic shift towards the electrification of large fleet vehicles. And it’s a transition that can’t come soon enough.
Fleet vehicles, including tractor-trailers, pickups and large vans, delivery trucks, buses and garbage trucks, move the goods we consume and provide a cost-effective and relatively energy-efficient way to get people where they need to go. Although they account for less than 8% of all vehicles on the road, trucks and buses account for more than 35% of direct road transport CO2 emissions.
But policy support for greening corporate fleets is expanding. Twenty-seven nations have signed a memorandum of understanding on zero emissions

Committing to a one-time target of reducing zero emissions by 30% in the sale of medium and heavy vehicles (including buses) by 2030. Separately, a group of nine nations has committed to 100% zero-emission trucks and buses,
The price and operational challenges involved in switching to electric buses and trucks are not trivial. Fleet electrification will not only require large amounts of electricity, but may also require new substations and other improvements to the power grid, as well as facility space reserved for charging stations. However, the reality is that the dream of fleet electrification is becoming a reality.
Last year almost 66,000 electric buses and 60,000 medium and heavy trucks hit the roads worldwide. This represented approximately 4.5% of all bus sales and 1.2% of truck sales worldwide.
According to the International Energy Agency (IEA). Although the numbers may seem modest at first glance, global sales of electric buses and electric medium- and heavy-duty trucks are growing at double-digit rates.

The numbers reflect steady advances in battery technology over the past two decades, enabling higher densities that store much more energy in smaller packages. This has helped to expand the driving range to meet the operational needs of the zero-emission bus and medium truck fleet operating on a single charge. At the same time, lithium-ion batteries are available at much cheaper prices due to the continuous decline in production costs, as they are used in high-volume applications such as laptops, smartphones, cars and others. These intersecting trends have made truck and bus fleets ripe targets for decarbonisation.
The bus industry has a clear incentive to accelerate the deployment of e-bus networks. Although buses are praised as an environmentally friendly mode of transport, diesel engines produce large amounts of nitric oxide, nitrogen dioxide and particulates. (Particulate matter exposure has been directly linked to the creation of various health problems in humans.
) Eliminating emissions not only reduces the critical greenhouse gas, but also improves air quality, a particularly important concern in urban areas where buses and small and medium-sized trucks are particularly active.
While sustainability is clearly in the fleet operator’s interest, the case for electrification also reflects good business sense. In addition to the environmental benefits, there are many economic benefits from fleet electrification, including fuel and maintenance cost savings, improved brand reputation, vehicle networking opportunities, government incentives and job growth.

Municipalities that switch to electric buses also gain operational advantages. E-buses may initially cost more than diesel buses due to battery costs. But after taking into account the total cost of ownership over a projected lifetime of 16 years, e-buses are cheaper than diesel buses. They’re easier to maintain: mechanics don’t have to change filters or deal with the many moving parts found in vehicles powered by complex internal combustion engines. The simplification of the power train to one electric motor, drive and battery eliminates a lot of trouble and work.
As fleet operators embark on what will be a complicated journey, they rely on Hitachi’s expertise to navigate this transition. As a leading global company and a pioneer in transportation solutions for more than a century, Hitachi is providing the infrastructure that partners and customers are using to transform their operations for a carbon-neutral future. For example, Hitachi Energy Canada Inc. is providing a grid-to-plug solution for an electric bus pilot project being conducted by Réseau de transport de la Capitale (RTC), the urban public transit provider in Greater Quebec City.
The Quebec government plans to electrify 55% of its city buses and 65% of its school buses by 2030.
The three-year trial, which began at the end of 2022, is an important step towards electrifying RTC’s entire bus fleet and reducing CO2 emissions in the province. It features Hitachi Energy’s Grid-eMotion® Fleet, a grid-to-plug solution that has been deployed in sustainable transport projects in some of the world’s largest urban bus systems, including London and Berlin.

The result of the Quebec pilot will provide important learnings for the expansion of electrification infrastructure in existing urban garages. Already cramped, these aging spaces don’t have much room for traditional individual chargers to provide the megawatts needed to power fleets. But Grid-eMotion
Fleet is an integrated charging system that starts at 1 megawatt, expandable to a multi-megawatt system, with the ability to connect to a medium voltage grid connection. This technology makes it possible to reduce the space required for charging a large-scale electric vehicle fleet by 60 percent and reduce the amount of cables needed in the warehouse by 40 percent.
This is just the beginning. Fleets understand that electrification projects will be critical in efforts to reduce greenhouse gas emissions. Now that technology is available to help you reach that goal, it helps to have a technology partner ready to stand by you every step of the way.

This is not a revolutionary idea, yet few towns and cities seem to be implementing it with the scale and will to significantly improve their urban environments and the lives of the growing number of people who inhabit them.
France Bans Short Haul Flights Where Trains Are Available
To me sustainable transport includes walking, mobility aids, cycling, public transport (trains, trams, buses.) The jury is out on new variants such as ‘on-demand’ minibuses, which seem to have more overlap with taxis that they have and currently take a day. amount of road space per passenger similar to private vehicles and taxis. The inverted traffic pyramid shown here provides a great way to rethink how we move efficiently in cities and how funds should be prioritized to reflect that. It was a major moment recently when the mayor of Paris, Anne Hidalgo, tweeted this image, bringing the concept to a mainstream audience.
