Good day, this is your friend with a look at the winds of change sweeping across our world. From the waters around Australia to the boardrooms of Europe, the clean energy revolution is picking up speed. These aren’t just stories about wind turbines and power cables. They’re stories about nations and companies making billion dollar bets on a cleaner tomorrow.
There’s good news from Down Under today. Australia and Tasmania are officially connecting their power grids with a massive underwater cable project called the Marinus Link.
The project just got final approval from shareholders including the Commonwealth of Australia, the State of Tasmania, and the State of Victoria. Construction begins in twenty twenty six, with completion set for twenty thirty.
This isn’t just any cable. When finished, it will help deliver clean renewable energy from Tasmania to millions of homes on the mainland. The project promises to reduce electricity prices for consumers across the region.
Stephanie McGregor, the project’s chief executive, says this will change the course of a nation. She’s right. When you connect clean energy sources across vast distances, everyone wins.
The Marinus Link will cement Australia’s position as a leader in the global energy transition. But this is just the beginning of our story from the land Down Under.
Here’s a story about big money backing clean energy. Spanish renewable developer Acciona is moving forward with a nine hundred ninety million dollar wind and battery project in central Victoria, Australia.
The Tall Tree project will include fifty three wind turbines and a massive battery storage system. Construction starts in twenty twenty seven, with operations beginning in twenty twenty nine.
But here’s what makes this special. The project has been carefully designed to protect local wildlife. Acciona surveyed eighty two threatened plant species and fifty six animal species near the site. They’ve already reduced the project footprint by more than twenty four square kilometers to protect high value vegetation areas.
This massive investment will create construction jobs and long term maintenance positions in the region. It will also provide clean electricity to power hundreds of thousands of homes while reducing reliance on fossil fuels.
When companies invest nearly a billion dollars in clean energy, they’re betting on a cleaner future. And Australia isn’t the only place where that smart money is flowing.
The Bank of Ireland is making headlines today with its largest green investment ever. The bank has committed eighty million pounds to East Anglia Three, an offshore wind farm that will become the world’s second largest when it begins operating next year.
Located seventy miles off England’s east coast, East Anglia Three will generate enough clean electricity to power more than one point three million homes.
John Feeney, chief executive of the bank’s corporate division, calls this exactly the kind of transformative investment that drives innovation and accelerates the energy transition.
This follows the bank’s earlier ninety eight million pound commitment to Inch Cape wind farm off Scotland’s coast. The Bank of Ireland has set a target of thirty billion euros in sustainability related lending by twenty thirty. They’ve already reached fifteen billion in the first quarter of this year.
When major financial institutions back clean energy this aggressively, they’re signaling where the smart money is going. But what happens when even the biggest players need to adjust their sails?
Denmark’s Orsted is recalibrating its strategy amid changing market conditions. The company is considering raising up to five billion euros to strengthen its financial position while scaling back some expansion plans.
Orsted has reduced its twenty thirty installation targets from fifty gigawatts to between thirty five to thirty eight gigawatts. But don’t mistake this for retreat. The company is focusing on high margin, high quality projects while maintaining its leadership in offshore wind.
The company’s Revolution Wind project in Rhode Island and Sunrise Wind in New York remain on track for completion in twenty twenty six and twenty twenty seven. These projects will deliver clean electricity to millions of Americans.
CEO Rasmus Errboe is implementing aggressive cost cutting measures, including reducing fixed costs by one billion Danish kroner by twenty twenty six. The company plans to divest one hundred fifteen billion kroner worth of assets to free capital for core projects.
Sometimes the smartest strategy is knowing when to consolidate and focus on what you do best. For Orsted, that’s building the world’s most efficient offshore wind farms. And speaking of strategic thinking, Europe is planning ahead for energy independence.
Germany is leading a European push to reduce dependence on Chinese permanent magnets. The German wind industry has proposed that Europe source thirty percent of its permanent magnets from non Chinese suppliers by twenty thirty, rising to fifty percent by twenty thirty five.
Currently, more than ninety percent of these vital rare earth magnets come from China. The German Federal Ministry for Economic Affairs and Energy is backing this diversification effort, working with industry associations to identify alternative suppliers.
The roadmap calls for turbine manufacturers to establish contacts with new suppliers by mid twenty twenty five, with production facilities potentially operational by twenty twenty nine.
Karina Wurtz, Managing Director of the Offshore Wind Energy Foundation, calls this a strong signal toward a new industrial policy that addresses geopolitical risks.
This isn’t just about reducing dependence on one country. It’s about building resilient supply chains that ensure the continued growth of clean energy. When an industry plans this thoughtfully for its future, that future looks very bright indeed.
You see, the news stories this week tell us something important. From Australia’s underwater cables to Germany’s supply chain strategy, the world is building the infrastructure for a clean energy future. Billions of dollars are flowing toward wind power. Major banks are making their largest green investments ever. Even when companies face challenges, they’re doubling down on what works.
The wind energy industry isn’t just growing. It’s maturing. It’s getting smarter about where to invest and how to build sustainably. And that means the winds of change aren’t just blowing… they’re here to stay.
And now you know… the rest of the story.

Joint Statement from ACP, ACORE, and AEU on DOE Grid Reliability and Security Protocol Rehearing Request
WASHINGTON, D.C., August 6, 2025 – The American Clean Power Association (ACP), American Council on Renewable Energy (ACORE), and Advanced Energy United, released the following statement after submitting a joint rehearing request to urge the Department of Energy (DOE) to reevaluate their recent protocol issued with the stated goal of identifying risk in grid reliability and security:
“As demand for energy surges, grid reliability must rely on sound modeling, reasonable forecasts, and unbiased analysis of all technologies. Instead, DOE’s protocol relies on inaccurate and inconsistent assumptions that undercut the credibility of certain technologies in favor of others.
“Americans deserve to have confidence that the government is taking advantage of ready-to-deploy and affordable resources to support communities across the country. Clean energy technologies are the fastest growing sources of American-made energy that are ready to keep prices down and meet demand.
“Providing a roadmap that offers a clear-eyed view of risk is critical to meeting soaring demand across the country. The Department of Energy report missed the opportunity to present all the viable types of energy needed to address reliability and keep energy affordable. We urge DOE to reevaluate and enable those charged with securing and future-proofing our grid to meet the moment with every available resource.”
