Flying isn’t so popular right now due to the pandemic and many airlines are financially hurting, and in France they are helping the Air France. Due to ineffectiveness in the private company the French government stepped in and doubled it’s stake with one key condition: the airline eliminates some of its routes. Short flights of 2.5 hours or less will no longer be permitted in France as the carbon output of one of those flights is 77 times that of a train. Train service in the country is good, but with the additional passenger load the service will improve with expansion.
Given how horrible plane travel is for the environment all of use should be grateful for France leading the way on this smart transportation policy.
The measures could affect travel between Paris and cities including Nantes, Lyon and Bordeaux.
The French government had faced calls to introduce even stricter rules.
France’s Citizens’ Convention on Climate, which was created by President Emmanuel Macron in 2019 and included 150 members of the public, had proposed scrapping plane journeys where train journeys of under four hours existed.
The 1970s oil crisis left an impact on the city of Denver in the forms of good public transit. The writing was on the wall that individualized transit infrastructure that favoured the automobile wouldn’t be a good long-term solution for the city so they did something. Thanks to the initiative taken decades ago Denver witnessed how good transit infrastructure built for people can positively shape a city. Since then light rail has been added to the city thus saving itself from turning into a generic, sprawling, and parking filled North American sub-urban community.
“We are talking about a culture-transforming moment,” says Denver mayor Michael Hancock. “Light rail has really moved Denver into the 21st century.”
How the $7.6 billion FasTracks project saved Denver from a dreaded fate locals call “Houstonization” is the story of regional cooperation that required the buy-in of businesspeople, elected officials, civil servants and environmentalists across a region the size of Delaware. Their ability to work collectively—and the public’s willingness to approve major taxpayer investments—has created a transit system that is already altering Denver’s perception of itself, turning an auto-centric city into a higher-density, tightly-integrated urban center that aims to outcompete the bigger, older coastal cities on the global stage.
The answer for how their famous bullet trains move so quickly is thanks in part to biomimicry, the study of using animals as a source for design. The front of the bullet train was inspired by the beak of a kingfisher which allows for more efficient airflow and thus less of an environmental impact. This is merely one example of the interesting world of using the evolution of animals to design the world around us.
Japan’s Shinkansen doesn’t look like your typical train. With its long and pointed nose, it can reach top speeds up to 150–200 miles per hour.
It didn’t always look like this. Earlier models were rounder and louder, often suffering from the phenomenon of “tunnel boom,” where deafening compressed air would rush out of a tunnel after a train rushed in. But a moment of inspiration from engineer and birdwatcher Eiji Nakatsu led the system to be redesigned based on the aerodynamics of three species of birds.
Nakatsu’s case is a fascinating example of biomimicry, the design movement pioneered by biologist and writer Janine Benyus. She’s a co-founder of the Biomimicry Institute, a non-profit encouraging creators to discover how big challenges in design, engineering, and sustainability have often already been solved through 3.8 billion years of evolution on earth. We just have to go out and find them.
The largest railway system in the world runs in India and it consumes a lot of energy to run it. Back when oil was more expensive they started looking into way to lower their fuel bill from using biofuel to solar. Today, they are running one solution that will save money in the first year of operations – putting solar panels on the roof of the train carriages. The panels will collect energy and store it in batteries instead of the current approach is using an additional diesel engine to power the carriages.
The rooftop solar system was developed by Noida-based Jakson Engineers, under the direction of the Indian Railways Organisation for Alternate Fuels (IROAF). “It is not an easy task to fit solar panels on the roof of train coaches that run at a speed of 80 km per hour. Our engineering skills were put to a real test during the execution of this rooftop solar project for Indian Railways,” Sundeep Gupta, vice-chairman and managing director of Jakson Engineers told the Business Standard newspaper. Established in 2008, the IROAF initially focused on bio-diesel and compressed natural gas (CNG) to help diversify Indian Railways’ fuel mix, before looking at solar.
Indian Railways has ambitious plans for solar. By 2020, the state-run transportation network plans to generate around 1,000 megawatts (MW) of solar power, which could be scaled up to 5,000 MW by 2025. These numbers are not only significant for the railways, given that it’ll help bring down the fuel bill, but will also impact India’s overall renewable energy goal of 175 gigawatt (1 GW = 1,000 MW) by 2022.
Trains are way more efficient than cars and trucks when it comes to transporting people and goods, yet in North America, trains are often shunned for more wasteful transportation systems. This negative attitude towards sustainability is changing, notably California citizens voted for a high speed rail line in the state.
Opponents to economic and environmental efficiencies argued that the high speed rail line would be too expensive to build. It turns out, rather unsurprisingly, that California’s new rail system is better for everybody!
While several competing proposals are on the table for what the system will look like once it’s completed, high-speed rail promises to be more environmentally friendly in several ways. Cars and planes, for example, run on fossil fuels, which emit greenhouse gases and other pollutants. The extraction and refining process also emits pollutants. High-speed trains, however, run on electricity, which produces no greenhouse gases at the point of use. Pollutants become an issue for high-speed rail at the power plants generating the electricity. The plants may burn fossil fuels. However, the study’s authors note that the number of renewable energy plants, which produce no greenhouse gases, will continue to grow in California as the high-speed rail system is built. Hydroelectric power produces the bulk of the electricity for the Swiss High-Speed Rail network.
The new study’s findings track closely with research commissioned in 2009 by seven of Europe’s leading high-speed rail systems. “Generally, what you tend to see around the rest of the world is a similar pattern where high-speed rail does have a lower environmental footprint than the automobile or aircraft,” Chester said.
