As the biggest players in wind energy gear up to report quarterly earnings, supply-chain reliability issues are front and center for both stock analysts and industry leaders.
Siemens Energy made the headlines earlier this year when it scrapped its profit forecast and warned that costly failures at wind turbine subsidiary Siemens Gamesa could drag on for years.
It sparked concerns about wider problems across the industry and thrust Europe’s wind energy giants’ earnings into the spotlight.
Siemens Energy is set to report its fiscal fourth-quarter results on Nov. 15. Its shares are currently down more than 35% year-to-date.
Aside from the turbine problems, the German energy giant posted orders of around 14.9 billion euros ($15.7 billion) for its third quarter, a more-than 50% increase from the previous year, primarily driven by large orders at Siemens Gamesa and Grid Technologies. Yet the 2.2 billion euro charge due to Gamesa’s quality issues prompted Siemens Energy to forecast a net loss for the fiscal year of 4.5 billion euros.
Ahead of its fourth-quarter earnings, analysts at Kepler Cheuvreux suggested in a research note Tuesday that despite having already warned on profits, the company “remains vulnerable to large negative cashflow swings in the next fiscal year.”
“We expect Siemens Gamesa to suffer very weak order intake in H1, which will combine with extensive delivery delays and rising customer penalty payments. Challenges at Siemens Gamesa will continue to overshadow resilience in the group’s other divisions,” they added.
Morgan Stanley cut its price target for Siemens Energy from 20 euros per share to 18 euros per share, but retains an overweight long-term strategic position on the company’s stock.
“Valuation for Siemens Energy is currently factoring in a negative value for the Gamesa division, which we believe may have been over penalized,” Morgan Stanley capital goods analyst Ben Uglow said in a research note Monday.
“While we acknowledge the low visibility on Gamesa margin trajectory and that rebuilding investor confidence will take time, we remain Overweight on undemanding valuation and good fundamentals of the Gas & Grid businesses.”
Elsewhere, Deutsche Bank earlier this week slashed its 12-month share price forecast for Danish wind energy producer Ørsted by 36% ahead of its interim earnings report on Nov. 1. The stock has already halved in value so far this year.

Deutsche had previously highlighted challenges in the wind turbine industry including supplier delays, lower tax credits and rising rates. However, Ørsted’s share price tanked further earlier this year when it raised the possibility of a 2.1-billion-euro impairment charge in its U.S. offshore wind portfolio.
Meanwhile, Danish wind turbine manufacturer Vestas — despite continuing to bag significant orders — has seen its shares plunge by around 30% year-to-date as reliability concerns plague the wider industry. Vestas publishes its interim financial report for the third quarter on Nov. 8.
Supply chain worries
ONYX Insight, which monitors wind turbines and tracks over 14,000 across 30 countries, revealed in a report Tuesday that supply chains remain the greatest challenge to the sector, with reliability not far behind.
The analytics firm, which is owned by British energy giant BP, interviewed senior personnel at over 40 owners and operators of wind turbines around the world in order to gauge the mood of industry leaders, and found that 57% cited the supply chain as the main obstacle to their operations.
ONYX Chief Commercial Officer Ashley Crowther said the lingering impacts of Covid-19 on manufacturing had just begun to heal — and then Russia’s invasion of Ukraine and the subsequent surge in inflation hit.
“Survey participants are now citing delays on new projects due to longer lead times for supply of new turbines and significant price increases,” Crowther said in the report.
“This is in line with what OEMs have told their investors, for example Vestas noting in their 2022 annual report they ‘increased our average selling prices of our wind energy solutions by 29%’. Similarly for major components, particularly main bearings on newer turbines with large rotor diameters, long delays are leaving turbines offline for extended periods.”
Although supply chain issues are creating problems for operators, the most direct impact has been on OEMs like Siemens Gamesa and Vestas, Crowther noted, as has been evident in recent financial results.
“Major western OEMs have recently reported losses or profit warnings and announced major restructuring projects in order to address the challenges they are facing. Some are even re-thinking their approach to the aftermarket which was always seen as the most profitable part of the business,” he added.
Reliability issues
Those surveyed by ONYX also expressed reliability concerns, with 69% expecting more reliability issues due to aging assets and 56% seeing problems associated with new turbine technology. Just 22% expected fewer reliability issues due to new turbine technology improvements.
“As the sector matures, turbines are getting older and the failure rate of electromechanical systems are increasing with age,” Crowther noted.
“Likewise, the initial operating period of newer turbines are seeing a rash of failures due to shorter development cycles, new turbine designs, and a squeeze on turbine prices. This is resulting in machines that are not durable enough.”
During an initial boom in the wind industry a number of years ago, OEMs faced huge market demand and, in turn, created a variety of turbine designs delivered on short cycles to a customer base seeking to generate more energy with greater efficiency at lower cost, Crowther explained.
“Fast-forward to the present and between the perfect storm of supply chain issues and too many turbine designs to support, OEMs have been losing significant amounts of money, including those paid out in liquidated damages (LDs),” he said.
“Manufacturers have been locked into a price competition spiral, attempting to produce larger turbines for more competitive pricing. But with bigger turbines produced in shorter production cycles, it’s no surprise that manufacturing quality has diminished.”
GM sold over 21,000 electric vehicles in the US last month, its best yet. Despite the surge in August sales, GM warned that with the “irrational discounts” on EVs set to end soon, the market is due for a shake-up.
GM sells record EVs in August as irrational discounts end
August was GM’s best month ever for EV sales. The company sold over 21,000 electric models under the Chevy, GMC, and Cadillac brands last month.
The higher demand comes as buyers rush to secure the $7,500 federal tax credit, which is set to expire at the end of September.
Driven by the hot-selling Chevy Equinox EV, Cadillac Lyriq, and GMC Sierra EV, GM remains the second-best seller of EVs behind Tesla.
GM expects to see strong demand again this month, but without the credit, it expects changes next quarter. GM said, “There’s no doubt we’ll see lower EV sales next quarter.” The company anticipates it will take several months for the market to correct, adding that “We will almost certainly see a smaller EV market for a while.”
Like several automakers in the US, GM will adjust production accordingly, promising not to overproduce. Despite slower sales, it remains confident that its EV market share will continue to grow.
Since affordable EVs and luxury models have been the strongest segments, GM believes it’s in a better position than most. It already has “America’s most affordable 315+ range EV,” the Chevy Equinox EV. The electric Equinox is one of the few EVs with a starting price under $35,000 in the US.
Soon, the new Chevy Bolt EV will debut, which is expected to be even more affordable, starting at around $30,000.
With a full line-up of electric SUVs, Cadillac is the leading luxury EV brand, but that doesn’t include Tesla. And then there’s the Chevy and GMC electric pickup with segment-leading range, features, and more.
GM said as it adjusts to the “new EV market realities,” its ICE vehicles will provide flexibility while driving profits. We will learn more on October 1 when GM reports full third-quarter sales results.
Although I wouldn’t call it “irrational,” GM is offering generous discounts on EVs with the deadline approaching. The Chevy Equinox EV is listed for lease starting at just $249 per month with a new $1,250 conquest bonus. Chevy is also offering the $7,500 credit on top of 0% APR financing until the end of September.

Global solar installations are breaking records again in 2025. In H1 2025, the world added 380 gigawatts (GW) of new solar capacity – a staggering 64% jump compared to the same period in 2024, when 232 GW came online. China was responsible for installing a massive 256 GW of that solar capacity.
For context, it took until September last year to pass the 350 GW mark. This year, the milestone was achieved in June. That pace cements solar as the fastest-growing source of new electricity generation worldwide. In 2024, global solar output rose by 28% (+469 terawatt-hours) from 2023, more growth than any other energy source.
Nicolas Fulghum, senior energy analyst at independent energy think tank Ember, said, “These latest numbers on solar deployment in 2025 defy gravity, with annual solar installations continuing their sharp rise. In a world of volatile energy markets, solar offers domestically produced power that can be rolled out at record speed to meet growing demand, independent of global fossil fuel supply chains.”
China’s solar dominance
China is leading this surge by a wide margin. In the first half of 2025, the country installed more than twice as much solar capacity as the rest of the world combined, accounting for 67% of global additions. That’s up from 54% in the same period last year. Developers rushed to complete projects before new wind and solar compensation rules took effect in June, fueling the spike. While that may lead to a slowdown in the second half of the year, new clean power procurement requirements for industry and bullish forecasts from China’s solar PV association (CPIA) suggest that 2025 will still surpass 2024’s record high.
The rest of the world
Other countries are adding solar at a healthy clip, too. Together, they installed an estimated 124 GW in the first half of 2025, a 15% year-over-year increase. India came in second with 24 GW, up 49% from last year’s 16 GW. The US ranked third with 21 GW, a 4% gain year-over-year despite recent moves by the Trump administration to suppress clean power deployment. Germany and Brazil saw slight dips, while the rest of the world added 65 GW, a 22% rise over 2024.
Africa’s solar market is also stirring. The continent imported 60% more solar panels from China over the past year, though a lack of reliable installation data makes it a challenge to track the true pace of deployment.
With installations surging across major markets and China driving the charge, 2025 is on track to be another record-breaking year for solar power.

Porsche just axed two of its most iconic models. The gas-powered 718 Cayman and Boxster sports cars have been discontinued, with their new EV successors set to debut next year. However, Porsche isn’t the only brand killing off a popular nameplate.
Sports cars are due for EV successors in 2026
As it prepares for the all-electric replacements, Porsche has stopped taking new orders for the 718 Cayman and Boxster. For now, you can still order the vehicles from stock.
We’ve known for years that an electric replacement was on the way for the 718 lineup. Porsche CEO Oliver Blume confirmed in 2022 that the electric 718 successor would follow the Taycan and Macan EVs.
Although the new Cayman and Boxster EVs were expected to launch by the end of this year, it was pushed back due to software and battery sourcing delays.
Porsche initially planned to build the EV versions alongside the current ICE models at its Zuffenhausen plant, but that will no longer be the case. Despite rumors that Porsche was planning to extend 718 production, “high-ranking Porsche sources” told Autocar that’s not the plan.
The luxury sports car maker has dialed back its EV plans recently, with ICE Macan and Cayenne models now due to be sold alongside the electric versions.
Meanwhile, Porsche isn’t the only sports car maker killing off models with new EV successors on the way. Audi confirmed with Autoblog that the A7 and S7 will be discontinued after the 2025 model year.
In a statement, Audi said, “There are no 2026 Model Year A7 or S7 being offered as production shifts to the new A6 TFSI coming later this year.” However, the RS7 will live on as a 2026MY. The ICE A7 will be rebranded as the A6 TFSI, while the EV version will retain the A6 E-tron name, featuring a similar sportback design to the outgoing model.
Porsche and Audi have leaned into a more flexible “multi-energy” strategy, blaming slowing EV sales and a changing market.
Just last week, Porsche announced it no longer plans to build EV batteries in-house. Instead, it will focus on research and development.
