Solar energy production in Germany is approaching a historic milestone, with output expected to exceed 100 terawatt-hours in a single calendar year. As the nation celebrates this renewable energy milestone, economics experts are issuing warnings regarding a potential federal budget crisis and urging caution against relying on single digital service providers.
Solar Power Production Narrows in on Record Total
Driven by an above-average number of sunshine hours and a growing number of photovoltaic installations, Germany’s solar energy output reached 90.2 terawatt-hours by September 27. According to the German Solar Association (BSW-Solar) in Berlin, this already surpasses the 90 terawatt-hours generated during the entire year of 2025.
This output means net electricity generation from solar power is projected to surpass 100 terawatt-hours over the course of the calendar year. This figure is nearly 10 times the annual electricity usage of a major city like Hamburg and approximately 50 times the 2.2 terawatt-hours produced by solar energy two decades ago.
Carsten Körnig, the managing director of BSW-Solar, stated that the anticipated record marks a crucial milestone in the global transition away from climate-damaging fossil fuels. Photovoltaics has transformed from a niche technology into a cornerstone of the national electricity supply, bringing benefits such as cheaper electricity, reduced energy imports, and fewer climate-related damages, according to Körnig. Photovoltaics accounted for 17.8% of total power generation, making it the third most important domestic energy source behind wind power and coal.
Experts Predict Budget Crisis Without Spending Cuts
Leading economic experts have cautioned that Germany faces a serious budget crisis starting next year unless spending is properly addressed. These warnings follow the Bundestag budget committee’s early Friday approval of a provisional 2027 federal budget after nearly 16 hours of negotiations.
The approved budget anticipates new debt, including loans from special funds, totaling around €210 billion ($231.5 billion). Spending within the core budget climbs to a record €561 billion, while net borrowing in the core budget alone reaches nearly €123 billion.
Clemens Fuest, president of the Ifo Institute in Munich, told the Sunday edition of Die Welt newspaper that the current budget policy is unsustainable in the long term and requires established spending priorities. Fuest stated that all other spending should be frozen or cut where possible, adding that tax increases would become inevitable otherwise. Jens Boysen-Hogrefe of the Kiel Institute for the World Economy (IfW Kiel) shared a similar outlook, pointing to a negative trend driven by an aging population and rising interest payments.
Ansgar Heveling, president of the federal audit court (Bundesrechnungshof), urged the coalition government to increase consolidation efforts. Highlighting that every third euro spent by the government is financed through borrowing, Heveling noted that the country is living beyond its means and warned that the share of interest spending in the federal budget would double by 2020.
Digital Dependency Warnings Following Microsoft Outage
Following a massive worldwide outage affecting Microsoft services, German experts have cautioned companies, schools, and government authorities against depending on a single digital service provider. Ralf Wintergerst, president of the industry association Bitkom, stated that relying unilaterally on a single source for central digital technologies risks production downtimes and competitive disadvantages during emergencies.
Christopher Kunz, an IT security expert from the Heise Online trade magazine, explained that such dependency threatens German society and the economy because the nation remains at the mercy of both Microsoft’s technical competence and the goodwill of the US government. Kunz added that sanctions could enable the US government to cut off access to the Microsoft cloud for individual organizations or entire nations instantly. Manuel Atug, founder and spokesperson for AG Kritis, noted that sufficient alternative providers exist within Germany and Europe to allow for proper diversification. Central services of the Microsoft 365 suite, including Outlook, Teams, and Copilot, experienced worldwide outages starting Thursday.
Lufthansa Operations and Political Updates
In other developments, the Lufthansa airline group reported being only slightly affected by Friday’s temporary suspension of flights to the United States caused by US air traffic control system issues. Most Lufthansa flights operated on schedule despite some cancellations or delays, with normal operations expected to resume on Saturday.
In national politics, the far-right Alternative for Germany (AfD) party nominated 62-year-old former football player Thomas Berthold as its candidate for the next German president. AfD co-leaders Alice Weidel and Tino Chrupalla wrote on X that their candidate could be chosen across party lines. The nomination drew criticism from Stephan Mayer, sports policy spokesman for the conservative bloc, who remarked that Berthold had made questionable statements during the coronavirus pandemic. Ilse Aigner of the Bavarian Christian Social Union (CSU) is widely viewed as the favorite to succeed current President Frank-Steinmeier in the January 30 vote.
Meanwhile, the Green Party in Mecklenburg-Western Pomerania approved a coalition agreement negotiated with the SPD and the Left Party. Incumbent state premier Manuela Schwesig of the SPD plans to stand for reelection on Monday, with the designated coalition holding 39 seats in the 71-seat state parliament.
