Solar power plant in Vienna a nature habitat

A solar power plant in Vienna serves a double function - not only does it create renewable energy, but it also provides an optimal habitat for endangered insects and small mammals.

The solar power plant in Liesing, which was built in 2013, produces 1,000 MWh annually and supplies around 400 households.

It also offers a home to 13 protected species of grasshoppers and crickets, praying mantis, as well as field hamsters, moths, snails, lizards, spiders and beetles.  

“Since there’s lots of space in between the solar modules we can secure these areas and create a rich area of habitat,” Thomas Proksch, owner of landscape planning offices Land Ahoy said. The area is around the size of two football pitches. 

A special method of mowing the grass ensures that the grasshoppers’ optimal habitat is preserved. The area directly under the solar panels is warm – which is also beneficial for the grasshoppers.

“We’re not only concerned about the environment, but also about wildlife conservation,” Wien Energie CEO Susanna Zapreva said.

“In the next five years we plan to invest €800 million, and more than half of that will be on renewable energy,” she added.

At present only one percent of electricity in Austria is produced from photovoltaic systems – far behind Germany which produces 4.5 percent of its energy from solar power.

Gerhard Heilingbrunner, president of Austria's environment association, has said that 55 percent of roof surfaces in Vienna would be well suited for solar panels.

Vienna residents can purchase up to ten photovoltaic panels from Wien Energie. Each panel costs €950. They then rent the panels back to Wien Energie and receive an annual fee of €29,45, per year, per panel – for a minimum of five years.

After around 25 years Wien Energie buys the solar panels back and the resident is repaid in full.

What you need to know about the EU’s plan for a uniform phone charger

The European Union has approved a new regulation that would force tech companies to use a standard charger for mobile phones and electronic devices. What does this mean?

What you need to know about the EU's plan for a uniform phone charger

The European Parliament has approved an agreement establishing a single charging solution for frequently used small and medium-sized portable electronic devices. The law will make it mandatory for specific devices that are rechargeable via a wired cable to be equipped with a USB Type-C port.

The rules have been debated for a while, and the announcement of the agreement has caused controversy, especially among tech companies and enthusiasts. US giant Apple has repeatedly lobbied against the standardisation, saying it halts innovation.

The EU says that the new rules will lead to more re-use of chargers and “help consumers save up to €250 million a year on unnecessary charger purchases”. Disposed of and unused chargers are estimated to represent about 11,000 tonnes of e-waste annually, the bloc says.

So, what exactly are the changes?

Which products will be affected?

According to the European Parliament, the new rules are valid for small and medium-sized portable electronic devices. This includes mobile phones, tablets, e-readers, earbuds, digital cameras, headphones and headsets, handheld videogame consoles and portable speakers that are rechargeable via a wired cable.

Laptops will also have to be adapted, the EU says.

Those devices will have to be equipped with a USB Type-C port regardless of their manufacturer.

When will the changes come?

For most devices, the changes are set to come by autumn of 2024. However, the date is not yet set because the regulations need to go to other proceedings within the EU bureaucracy.

After the summer recess, The EU’s Parliament and Council need to formally approve the agreement before publication in the EU Official Journal. It enters into force 20 days after publication, and its provisions start to apply after 24 months, hence the “autumn 2024” expectation.

Rules for laptops are a bit different, and manufacturers will have to adapt their products to the requirements by 40 months after the entry into force of the laws.

Where are the rules valid?

The rules will be valid for products sold or produced in the European Union and its 27 member countries. But, of course, they will likely affect manufacturers and promote more considerable scale changes.

Why the uniform USB Type-C?

The bloc said the uniform charger is part of a broader EU effort to make products more sustainable, reduce electronic waste, and make consumers’ lives easier.

“European consumers were frustrated long with multiple chargers piling up with every new device”, EU Parliament’s rapporteur Alex Agius Saliba said.

USB Type-C is a standard of charging that has been around for a while but still is one of the best options currently in the market. Also known as USB-C, it allows for reliable, inexpensive, and fast charging. A USB-C port can also be input or output, meaning that it can both send and receive charges and data.

Unlike other ports, it can be the same on both ends of the wire (making it easier and more universal in its use). It can also power devices and sends data much faster.

USB-C can also be used for video and audio connections, so some external monitors can charge your laptop and show your screen simultaneously with the same cable.

What criticism is there?

The project is not without criticism, most vocally from US tech giant Apple, a company that famously has its own charging standard, the “lightning” connection.

Apple claims that forcing a standardisation will prevent innovation, holding all companies to the same technology instead of allowing for experimentation. Still, Apple itself has been swapping to USB-C. Its iPads have already dropped the lightning standard. Its newer laptops can now be charged with the MagSafe proprietary connector and USB-C.

The company’s popular earbuds and peripherals (including keyboards and mice) all charge with lightning. And, of course, the iPhone, Apple’s smartphone, also uses the company’s connection for charging.

While there have been rumours that Apple is working on new iPhones with USB-C connection (though definitely not for the next launch this year’s), the company could go away with wired charging altogether. Instead, like many tech manufacturers, Apple is improving its wireless charging solutions, even creating products dedicated to its MagSafe charging.

It won’t be completely free from the EU regulation if it does that, though. This is because the rules approved by the EU also allow the European Commission to develop so-called “delegated acts” concerning wireless charging. The delegated acts are faster processes that can be applied directly without being put to the vote.
