Renewables like wind need 10 times the material: Siemens CEO
The CEO of Siemens Energy on Wednesday argued that the energy transition would fail unless his industry addressed a number of issues currently facing the wind power sector. In an interview with CNBC’s “Squawk Box Europe,” Christian Bruch said his firm was “in the heart of the energy transition” but noted that there were “challenges in wind” especially when it came to supply chains. “Never forget, renewables like wind roughly, roughly, need 10 times the material [compared to] … what . . .

Renewable power’s big mistake was a promise to always get cheaper
Renewable-energy producers have long touted the promise of cheap electricity, an assurance that’s helped them eat into the dominance of fossil fuels. But the pledge has gone too far, according to the world’s biggest wind-turbine maker. Manufacturers such as Vestas Wind Systems A/S are seeing losses pile up as orders collapse at a time when they should be capitalizing on the turmoil in natural-gas markets. To blame – at least in part – is the industry’s insistence that clean electricity can only . . . Complete story »
Arc flash risk in wind turbine renewables?
There have been a number of arc flash incidents and accidents reported on wind turbines. The arc flash hazards are similar for wind turbines as for other types of electrical installation. There are however some other things to consider with a wind turbine application: Wind turbines are often in remote locations, potentially making emergency response more difficult and slower e.g. offshore; on higher ground; away from centres of population Access and egress can be difficult due to the space restrictions . . .

Siemens Energy shares hit record low as wind turbine problems mount
Siemens Energy (ENR1n.DE) warned on Wednesday sales and margins this year would be at the low end of its forecast range due to worsening problems at wind turbine division Siemens Gamesa (SGREN.MC), which has been hit hard by supply chain disruptions. Shares in the company, which was spun off from Siemens (SIEGn.DE) in 2020, fell as much as 6.1% to their lowest level since they were separately listed, highlighting the need for a quick structural fix of Spanish-listed Siemens Gamesa. . . .

Offshore wind turbines can affect the weather on land, Danish research shows
Research from Denmark shows that offshore wind turbines can affect the weather several thousand kilometers away. According to research from the Danish Meteorological Institute, wind farms affect wind speed, precipitation, and temperature. The wind farms’ impact can be traced far inland. Professor Eigil Kaas says he is a strong supporter of wind turbines but notes that it is important to investigate how they affect the surrounding area. “And when there is a violent development of wind turbine (projects) in both . . .

Wind turbine makers struggle to find pricing power
Wind turbine makers racked up hefty losses last quarter, swelled by rocketing costs and cut-throat competition despite being more in demand than ever. The industry started seeing a steep decline in prices and increased competition back in 2017 as some governments moved away from generous, fixed, subsidised tariffs for power toward an auction-based system that favours the lowest bidders. Profits have been pummelled further by COVID-19, runaway metals prices, politically-motivated import duties and the fallout from Russia’s invasion of Ukraine. . . . Complete story »
Cement makers burn turbine blades as wind power faces recycling headache
Old wind-turbine blades are getting a new lease on life—in cement. Turbines are mostly made of steel, a widely recyclable material. But their blades are constructed of complex composite materials such as fiberglass and balsa wood that are difficult to separate and process, presenting a recycling challenge. As a result, blades that reach the end of their lives often end up in landfill. Last year, more than 12,000 blades were scrapped globally, according to data provider BloombergNEF, which expects the . . . Complete story »
Wind power’s ‘colossal market failure’ threatens climate fight
Optimism abounds about the future of wind power, with a clean-energy boom powering robust growth in an industry that businesses and governments agree is key to slowing climate change. But a nagging problem could keep the sector from fulfilling that promise: Turbine makers are still struggling to translate soaring demand into profit. Wind power heavyweights Vestas Wind Systems A/S, General Electric Co. and Siemens Gamesa Renewable Energy SA are reeling from high raw material and logistics costs, changes in key . . .

Die Energiewende bekommt ein Rohstoffproblem | Energy transition has a raw materials problem
Für die Energiewende braucht man enorme Mengen von Spezialrohstoffen. Von denen sind einige bereits jetzt knapp, auf andere haben einzelne Staaten beinahe Monopole. Fachleute warnen schon vor den nächsten Abhängigkeiten. Denn es gibt zwar Lösungswege für das Problem – die aber dauern lange und sind unbeliebt. Wer den Schwachpunkt der Energiewende sucht, muss sich in den Straßen von Belgrad umschauen. Tausende Menschen demonstrierten in den letzten Monaten in der Hauptstadt Serbiens gegen den australisch-britischen Konzern Rio Tinto, der in Jadar . . . Complete story »
Siemens Energy shares hit record low as sell-off continues
Shares in Siemens Energy (ENR1n.DE) hit a record low on Monday as a sell-off triggered by problems at its wind power division Siemens Gamesa (SGREN.MC) continued following a HSBC downgrade. Siemens Energy’s stock fell as much as 6.9% to 17.805 euros per share, its lowest since the company was spun off from former parent Siemens AG (SIEGn.DE) and listed separately in September 2020. On Friday Siemens Energy shares recorded their biggest intraday loss after Siemens Gamesa, in which it owns . . . Complete story »
