Germany still lacks many publicly accessible charging points to achieve the traffic turnaround with electric vehicles. This is because these vehicles need their own charging point. This cannot be located in the already well-developed network of charging stations without structural adjustments. Accordingly, the charging infrastructure and the speed of its expansion is a key factor for the future acceptance and spread of electric vehicles.

There has recently been good news on this front: The Federal Network Agency has recorded a continuous increase in available charging points. In 2021, the largest increase in charging stations to date took place with over 7,600 public charging points. At the same time, demand is significantly higher: in 2025, Germany will probably need over 250,000 charging points for electric vehicles. As 69% of those surveyed stated that they would not buy an electric car due to too few charging stations, investment in expansion is urgently needed.

At the same time, Germany intends to achieve its climate targets by reducing emissions in transport, among other things. There should be around 15 million electric cars by 2030. The federal government is funding the expansion of the necessary charging infrastructure – one million charging points are needed. For example, 800 million euros are available for private wallboxes, and consumers receive 900 euros for the expansion of charging points. So many applications have been received for this that the maximum funding amount has already increased several times.

The growing gap between the number of electric cars and the number of public charging stations is particularly problematic. Around 60 percent of private parking spaces for electric cars have a charging point, which means that over a third of the energy must be made available publicly or in company parking lots.

A data analysis shows that 27 electric cars in Germany currently have to share a charging station. At the beginning of 2023, around one million electric cars were registered in this country, a share of just over 2.1 percent of the total car fleet. According to map and navigation service provider Here Technologies, 105,000 public charging points are available.

Interactive maps on the service provider’s website show how many electric cars and charging points are available in each German district. This shows that most electric cars can be found in large cities, where there are also the most charging points. In Berlin, for example, 9 electric cars share a public charging point, while in Wiesbaden there are almost 50 vehicles.

In addition to the availability of charging points, users are also concerned about the charging time of electric vehicles. This is because combustion engines only need a few minutes to fill up. Electric cars need between one and five hours, depending on the model and power of the charging station. Fast-charging stations offer a higher kW output, allowing cars to charge to about half capacity in 30 minutes or less. However, there are still very few fast-charging stations in Germany.

In addition to the number of charging stations, some of which consist of several charging points, it is also useful to look at the distribution of the charging infrastructure in Germany. In Stuttgart, there are around 23 charging stations per ten square kilometers, while in the district of Mecklenburgische Seenplatte there are only 0.1 charging stations. The density is lowest in the center and east of Germany and highest in the west and south.

A Europe-wide comparison shows that the charging infrastructure in this country is very unevenly distributed. Although the number of electric cars in Germany is quite high, the number of charging points in an EU comparison and in relation to the number of cars is rather low. In the Netherlands, there are seven cars for every charging station.

The comparison by the British agency Uswich, which assesses the charging infrastructure in 33 major European cities, is also interesting. The Icelandic capital Reykjavík is at the top of the list, as 65% of charging stations here provide free electricity. At an average of 0.29 euros, the chargeable electricity is quite cheap – in Germany, prices range between 0.25 and 0.50 euros per kWh. Glasgow and Lisbon also perform well in the comparison due to a high density of charging stations and low prices. Cologne and Frankfurt, on the other hand, are further down the rankings, as charging is significantly more expensive here – and the charging infrastructure still leaves a lot to be desired.

In October 2022, Federal Transport Minister Volker Wissing adopted a master plan for the expansion of the charging network, which aims to provide one million publicly accessible charging points by 2030. There is a budget of 6.3 billion euros for this. For this to work, over 130,000 new charging points would have to be added every year from 2023.

The German Association of Energy and Water Industries expressed doubts about achieving this target. With the measures taken so far, figures such as 15 million e-cars by 2030 cannot be achieved. Furthermore, according to the association, it is not the number of charging stations that matters, but their performance. Accordingly, it advises that the focus of the charging infrastructure in Germany should be on improving charging capacity in order to be able to charge more vehicles per day.

In addition, the German government plans to implement further measures to reduce CO2 emissions in road traffic and promote electromobility. These include charging stations at transport hubs, the integration of fast-charging stations into the power grid, better digitalization of the charging station overview, new locations, the promotion of solar systems for self-sufficient drivers and investments in electric trucks. With the growth plan for e-mobility, electric cars could account for up to eight percent of electricity consumption in future instead of 0.5 percent.

Also exciting: in May 2022, G+L focused on the topic of mobility in Europe and presented many interesting projects.

Stonehenge highway tunnel unlawful according to court

The Stonehenge Alliance took legal action against the Stonehenge highway tunnel planned by highways england – and won.

The British government has been campaigning for several years to tunnel under the Stonehenge Stone Age monument. It argues that there will be less noise, less congestion and a better quality of life for residents in the surrounding villages. However, the opponents of the mega project are not impressed by this. They formed the Stonehenge Alliance and took legal action against the construction project – and were proven right.

Many stories and myths surround the Neolithic monument Stonehenge, which attracts thousands of visitors every year. Many of them arrive via the A303 highway, which passes within sight and, above all, within earshot of the monument. There is no question of mystical, romantic seclusion there.

Highways England, the state-owned company that looks after England’s freeways, wanted to do something about this. Its aim is to improve the A303, which connects England’s southwest with the southeast. At Stonehenge, the single-lane section is to be widened to two lanes. But that’s not all: a tunnel is planned right next to the Neolithic monument, which would take traffic out of sight of the landmark.

However, the planned reconstruction is not just for cosmetic reasons. According to highways england, it currently takes an hour or more – depending on the time of day – to pass Stonehenge on the highway. The expansion aims to reduce this time to eight minutes.

Two tunnels more than three kilometers long – one for each direction of travel – will run 200 meters underground next to Stonehenge, reconnecting the landscape on the surface for visitors, horse riders, cyclists and, of course, flora and fauna. Several new junctions will also prevent drivers from clogging up the surrounding villages to avoid traffic jams. Highways England planned to start the first phase of the mega project in 2023.

However, this will not happen for the time being. This is because a group of NGOs and individuals have come together under the name The Stonehenge Alliance to protect the World Heritage Site. The Stonehenge Alliance was formed back in 2001 to prevent the expansion of the highway in the World Heritage Site. In the end, this was actually put on hold – whether this result can be attributed solely to the Alliance remains unclear.

Today, the Stonehenge Alliance is speaking out against highways england’s mega-project with its Save Stonehenge World Heritage Site campaign. Their argument: the expansion and conversion would severely damage the landscape, which is considered one of the most archaeologically significant land areas in Europe. Among other things, the campaign criticizes the fact that highways england has not considered any alternatives, that previously undiscovered archaeological finds could be damaged and that local animals would be permanently disturbed by the construction work. Furthermore, too few clarifications had been made regarding flood risk, groundwater protection, geology and land contamination, as the subsoil is a unique limestone rock whose reaction to the planned measures is not certain.

Stonehenge ruling as a wake-up call for the government

In addition, the planned construction work violates the UNESCO World Heritage Convention and ignores UNESCO’s recommendations on the plans. This could lead to Stonehenge ending up on the red list of World Heritage in Danger. According to UNESCO, inscription on the red list is linked to specific requirements for remedying or averting the threat, a program for remedial measures and increased monitoring through annual reports on the state of conservation.

The Stonehenge Alliance’s objections have borne fruit. At the end of July, the High Court ruled that the British Transport Minister had acted unlawfully. He had not considered less harmful alternatives. For these reasons, the judge overturned the consent order issued by the British Transport Minister. According to the British news site BBC, the project will now be put on hold until the government has decided on its next steps.

John Adams, head of the Stonehenge Alliance, expressed his delight at the ruling in a press release: “Now that we are facing a climate emergency, it is all the more important that this ruling is a wake-up call for the government. It should re-examine its roads program and take action to reduce road traffic and remove the need to build new and wider roads that threaten the environment as well as our cultural heritage.”

That Stonehenge forms a large part of the UK’s cultural heritage is clear. Not only is it one of Britain’s most famous landmarks, it is also a masterpiece of engineering. It is located in England, between Bournemouth and Bristol, and is part of the Stonehenge, Avebury and Associated Sites World Heritage Site. The structure was built over a period of several hundred years – even before the invention of the wheel or before people started working with metal. Construction began as early as 3,000 BC, with the first of several stages.

The first monument – the first stage – consisted mainly of earthworks and was used for cremation burials. It was not until around 2,500 to 2,000 BC that the typical stones were added in further stages. Stonehenge as we know it today was created from huge sarsen stones weighing several tons and smaller bluestones. However, this required enormous efforts – moving this mass (and without using wheels!) would have required the manpower of hundreds of workers at the time. Not to mention the planning and organization. In total, the construction of Stonehenge took over 1,000 years.

So what was the fun for? There are several theories and myths surrounding the Neolithic monument, but no one can say for sure what the exact purpose behind it was. This is despite the fact that researchers have been studying it for decades. But Stonehenge is so old that there is no longer any collective memory that can recall its original purpose. There are no exact records that have survived the last 4,500 years – although there are of course some theories. These include, for example, that Stonehenge was a place for ceremonies, a sacrificial site or an observatory. The latter refers to the alignment of the STEINs, which are arranged according to the solstice and equinox.

For a long time, the area between Tel-Aviv-Straße, Perlengraben and Blaubach – an area in the middle of Cologne’s city center – was dominated by dreary functional buildings. The overall concept for the redesign by Cologne urban planner Boris Enning won over the jury of the architectural competition. The “55 Frames” project meets urban living requirements with different formats: from penthouses and individually designed apartments to townhouses and garden apartments on the first floor.

The eponymous frames, which protrude irregularly from the white outer façade like drawers being pulled out, structure the building and open up the living space to the outside, while offering the residents protection and security through the frames. Fastening the concrete frames in this project initially seemed difficult due to the high weight, but with the help of the “Isokorb type WXT” from Schöck, the required load-bearing capacity of the projecting wall panels and thus the “frames” was achieved without any problems: For this purpose, one wall panel was each connected to an Isokorb type WXT and the internal wall, the other wall panel is anchored in the external wall with a type WXT bent into the support, as there was no internal wall here for the back anchorage. The upper and lower ceiling panels are only fixed with the Isokorb supplementary type HP-XT and rest on or hang from the wall panels. The Isokorb type WXT is a load-bearing thermal insulation element with 120 mm insulation thickness for cantilevered wall panels.
