Charging at streetlights: an expensive experiment with limited benefits?
The challenge of electromobility is not only the purchase of the vehicles, but also the provision of a nationwide charging infrastructure. The Berlin start-up Ubitricity has come up with a creative solution: converting street lamps into charging stations. But the reality is sobering. According to current figures from the Berlin Senate, not even one in ten streetlights is suitable for conversion. In addition, the costs are considerable at 6000 euros per conversion (without network expansion).
How sunlight and CO2 can be turned into sustainable fuel
In a recent article published in the journal Sustainable Energy & Fuels, researchers present a new process that uses sunlight to convert CO2 into methanol. This methanol can be used as a sustainable fuel. This sounds promising, but is it too early to be jubilant?
E-cars lead to a billion-euro grave - this is how expensive the transport transition is
Germany is facing a major challenge: according to a study by management consultants EY, the transport transition could turn out to be a billion-euro grave for the treasury. The switch to electric cars could cost the state around 50 billion euros by 2030. This is a huge sum that not only puts fiscal policy to the test, but also climate and environmental targets.
Mega trucks in Europe: a curse or a blessing?
The sight of huge, powerful lorries on Europe's motorways could soon become a reality. The European Parliament recently passed a measure that could make it possible to allow so-called "mega trucks" on the roads of EU countries. But what does this mean for the climate? Can these giants really reduce emissions from freight transport?
Do we need more environmental zones for bees?
Particulate matter is not only dangerous for humans, but also for bees and other insects. New studies show that high concentrations of particulate matter in the air impair the ability of bees to perceive floral odours. As a result, they visit fewer flowers, which in turn leads to a decline in pollination. Without pollination, there is no fruit, no vegetables and no cereals. It's a worrying cycle that could have serious consequences for our ecosystem and ultimately our food supply.
ACEEE study: The most environmentally friendly car is not an electric vehicle!
Electromobility is a key building block for more sustainable mobility. Electric cars are considered to be significantly more environmentally friendly than their petrol-guzzling counterparts. However, a recent study by the American Council for an Energy-Efficient Economy (ACEEE) shows: Electric cars are not always the more environmentally friendly option. In 2024, a plug-in hybrid, the Toyota Prius Prime SE, will top the list of the most environmentally friendly cars. This is despite the fact that electric cars follow in the next four places.
Electric gate: Are car manufacturers deliberately deceiving on range?
The range of electric cars is a decisive factor when buying. But most cars never reach the manufacturers' specifications. Sales tricks to make the cars more attractive? The manufacturers reject the suspicion of deliberate deception. While the EU is still on the side of the manufacturers, things are getting tight for Tesla in the USA.
Superconductor highway: Dream or key to green mobility?
Thanks to superconductors, cars and trucks can not only travel at top speed, but can also do so completely free of local emissions. This is shown in a new study that explains the potential of superconducting highways for the transport turnaround - including in the promotion of hydrogen technologies.
Artificial leaf produces e-fuel
Like a miniature fuel production plant, the leaf produces bio-ethanol and -propanol from light, water and CO2. Applied on a larger scale, this could be an interesting solution for the climate-neutral production of synthetic fuels - and thus represent a further step away from fossil fuels.
Penguin droppings in the fight against climate change
The Earth's ecosystem is a play of complex interrelationships in which humans, plants and animals can contribute to the preservation of the planet in terms of climate protection. According to new findings, even penguins, as a crucial part of the South Pole ecosystem, contribute to the fight against climate change. They support the carbon cycle and air pollutant sequestration.
