In an interview with PV Magazine, Xavier Daval, President of the French solar association Ser-Soler, said the EU desperately needs a major European photovoltaic manufacturer. A complete exodus of the domestic solar industry to China and the US, he said, would drive Europe into energy dependency for decades to come. "We are not talking about a small task here. We are talking about the challenge of this century. When module manufacturing moved to China, the Germans thought they would continue to sell manufacturing equipment to Chinese solar producers. But now they have to look at equipping factories in China with locally made production lines. In the long run, this was a wrong decision. What the Europeans have to do now is to correct this situation. In the automotive industry, there are big players in Europe, China and the US. The same must now happen in the European solar industry. If we don't, we will be dependent on products from other regional markets in the future. For a century we have been dependent on oil from outside Europe. We must not allow a continuation of this dependency also in renewable energies and their technologies," says Daval.

Results: When analysing the total annual costs, the running costs and revenues in the utilisation phase are taken into account in addition to the capital-related investment costs. The result of this full cost calculation is a relatively homogeneous cost level for all building energy standards examined. Due to the subsidies for the better standards, lower energy costs and the use of subsidies, the cost level remains relatively constant among the building energy standards. Thus, higher building energy standards up to the "KfW 40 Plus Standard" are already economically attractive today.
The influence of building energy standards can be classified as subordinate when considering total consumer spending.

Recently, the Austrian state of Vorarlberg published the subsidy guidelines for 2020 and 2021 for residential renovation and new construction in the private and public sectors. The climate-friendly procurement of wood and wood products from the region is anchored in these guidelines. The origin of the wood must be proven by means of the "Holz von Hier" label recently introduced in Austria or comparable certificates.
Financial advantage for building owners through regional wood
If regional wood is used, the costs eligible for housing subsidies increase by 20 euros per square metre of roof and façade area, for example. For an average-sized single-family house, this can add up to around 4,000 to 5,000 euros. In the case of new buildings, the recognised costs for a loan under the housing subsidy also increase by 20 euros per square metre of floor space for the use of regional wood for the windows, and by as much as 30 euros for the façade.
"With this innovation, we have placed climate-friendly procurement in the foreground, without the risk of legal discrimination against companies in border regions," says Provincial Councillor Christian Gantner, emphasising the priorities. Unlike other quality labels, "Holz von Hier" is not oriented towards state or national borders, but only takes into account transport distances along the entire processing chain. Cross-border cooperation in the wood processing chain is thus strengthened. "In the long term, thanks to "Holz von Hier", regional, rural businesses can be strengthened and imports from more distant countries such as Russia and Scandinavia can be replaced," adds DI Andreas Amann, Head of the Forestry Department of the Provincial Government.
Trend reversal towards more regionality and climate protection in timber construction
The inclusion of the "Holz von Hier" label can stimulate demand among end customers for domestic timber. In public tenders, the proof of origin is already required in accordance with the law, since it has found its way into the specifications for the municipal building certificate. In order to use the label, the entire processing chain must be traceable - all companies from the sawmill to the dealer to the window manufacturer must join the initiative if they want to offer domestic wood with chain-of-custody certification.
"We think that with the inclusion of 'Holz von Hier' in the housing guidelines, a trend reversal towards more regionality and climate protection in construction can be initiated," hopes Erich Reiner, contact person for Holz von Hier in Austria. This could succeed even better if the regionality of the entire building construction is taken into account in future revisions of the subsidy guidelines. The climate-friendly use of wood is in line with the forestry strategy of the state of Vorarlberg and supports the efforts to achieve the energy autonomy goals.
Researchers at DIW Berlin have developed the "Ampel-Monitor Energiewende" - monitor the extent to which the government's energy policy agenda is being implemented - immense efforts are needed to close the gap between the announced targets and the current status quo
If the German government wants to achieve its energy policy goals, it must step up the pace. There are particularly large gaps between the current development and the targets for green hydrogen, electromobility and renewable heat, as the "Ampel-Monitor Energiewende" of the German Institute for Economic Research (DIW Berlin) shows. DIW researchers developed the monitor to track the progress of the energy transition towards climate neutrality using 15 indicators. The monitor, which is based on open data, accompanies progress on the government's goals with a focus on the period up to 2030. Selected results are now available on the DIW Berlin website (https://www.diw.de/ampel-monitor) are provided in the form of interactive graphics and short analyses and are updated regularly. All indicators and the underlying data can also be found open source on the Open Energy Tracker platform (https://openenergytracker.org).
"Our traffic light monitor makes it clear: the current pace of the energy transition is far too slow to achieve the 2030 targets," says DIW energy economist Wolf-Peter Schill, co-initiator of the monitor, which is presented in a study today. "If the government does not want to fall behind its target path, it must implement concrete and far-reaching steps promptly."
The pace of photovoltaic expansion must be tripled
The monitor shows: If the government wants to achieve its photovoltaic targets by 2030, it will have to triple the pace of expansion compared to the trend of the past twelve months, and even quadruple it for onshore wind power. At the current rate, the targets would clearly be missed. This would also make it impossible to achieve the coalition's goal of increasing the share of renewable energies in electricity consumption from the current 42 percent to 80 percent in 2030.
There is also a large gap in renewable heat, for which a share of renewable energies of 50 percent is envisaged in 2030. For this to happen, the share must grow by almost four percentage points per year - although it has not even increased by three percentage points since 2012.
"The Federal Government's to-do list is still long. The energy policy goals that have been set are not self-fulfilling; development must gain momentum in all areas." Alexander Roth
E-car fleet still growing very slowly - charging infrastructure inadequate
If the coalition's goal of increasing the e-car fleet to 15 million vehicles by 2030 is to be achieved, an average of around 130,000 vehicles must be registered in Germany every month. In addition to the existing purchase premiums, the EU ban on combustion engines, which is currently being voted on, could certainly contribute to more electromobility," explains study author Adeline Guéret.
According to the Monitor's data, the charging infrastructure must increase even more if the target is not to be missed. Instead of the current 1200 charging points per month, 8,700 would have to go into operation - around seven times as many.
From practically zero to ten gigawatts in green hydrogen
Most needs to happen with green hydrogen, as the traffic light monitor shows: The electrolysis capacity of around ten gigawatts in 2030 targeted in the coalition agreement still seems a long way off, given an electrical capacity of around 60 megawatts at the end of last year.
"With its open and constantly updated energy data, our traffic light monitor makes an important contribution to an informed and fact-based energy policy debate," concludes study author Alexander Roth. "It shows that the German government still has a long to-do list. The goals set are not self-fulfilling; development must gain momentum in all areas."
