Dobby’s Grave Spared as UK-Ireland Power Cable Redirected

A £430 million Greenlink undersea interconnector between the UK and Ireland was rerouted to avoid passing through Dobby’s memorial at Freshwater West beach in Wales after Potter fans highlighted the issue; the line’s goal is to move surplus renewable energy and boost energy transfer and security between the two nations, with officials noting the memorial can stay if visitors stop leaving socks as it runs on a new route near Bronze Age remains, benefiting Pembrokeshire’s tourism economy.

Solar Industry Bets Big to Oust Ogles in Tennessee

A renewables-backed Invest in Tomorrow Coalition PAC spent about $2 million to help Charlie Hatcher defeat Rep. Andy Ogles in Tennessee, using ads that highlighted voting records rather than energy issues. The move signals the solar industry’s growing willingness to wage targeted political battles to punish lawmakers who oppose renewables and to build a broader, more aggressive influence operation for future races.

Tidal Turbines: High Potential, High Hurdles

Tidal Turbines: High Potential, High Hurdles

Tidal energy could provide strong, near-zero-emission power by harvesting ocean tides with underwater turbines, but faces steep upfront costs, site-specific constraints, and environmental concerns; tides are predictable but intermittent, so tidal power would need storage or backup and is currently viable mainly in a few favorable coastlines (e.g., Sihwa Lake at 254 MW).

Geothermal roots: how Iceland heated its way to a renewable energy frontier

Iceland transformed a volcanic landscape into a clean-energy powerhouse by expanding geothermal heating and renewable electricity generation through decades of drilling, public investment, and shared infrastructure; today nearly all homes are heated by geothermal water and electricity is largely renewable (hydro and geothermal), reducing carbon emissions and delivering substantial economic benefits—potentially up to about 7% of GDP through avoided fossil-fuel costs.—bot_challenge:false} }``` However, I included trailing characters that might be misinterpreted.

Grid-First AI Power: Building a Clean, Flexible Grid for the Data-Center Era

Grid-First AI Power: Building a Clean, Flexible Grid for the Data-Center Era

AI data centers are poised to push U.S. electricity demand from about 31 GW to 66 GW, stressing aging infrastructure and potentially driving up costs and outages. Experts argue the fix isn’t just building more generation but upgrading the grid with a diversified mix of clean, firm power, enhanced reliability, and smarter demand management. Proposals include Enhanced Geothermal Systems for baseload, grid-friendly data centers with on-site storage and flexible workloads, and policy tools like a grid infrastructure fund, pricing incentives, and transparency on energy use and emissions. The result would be a co-designed AI–energy system that keeps data centers powerful and the grid resilient as electrification progresses.

Beaver Island Trials Wave Power to Boost Local Energy Resilience

Beaver Island Trials Wave Power to Boost Local Energy Resilience

Researchers on Beaver Island in Lake Michigan tested two small wave-energy devices that generated enough electricity to light a bulb and charge a phone, a potential step toward a more reliable, locally produced power source for a remote community. Funded by NSF and part of a broader U.S. push to commercialize wave power, the project highlights promising progress but also challenges—high costs, deployment hurdles, and dependent funding—while the Great Lakes provide a safer, real-world testing ground for inland-sea wave technology.

Italy Joins Swiss Solar Rail Push as Sun-Ways Expands Across Europe

Swiss startup Sun-Ways' pilot of solar panels mounted between tracks in Buttes produced about 16,000 kWh in its first year and a plan for a permanent installation, with the potential to supply roughly 1 TWh annually across Switzerland’s rail network. Building on that success, Italy is planning a pilot with Rete Ferroviaria Italiana, while Sun-Ways pursues projects in Korea and partnerships with Dutch, Chinese, Indian and Singaporean firms—often highlighting rugged panel design, anti-reflection features, and in-train cleaning to address safety concerns.

Space elevators: could we climb to orbit on a 100,000-km tether?

Space elevators: could we climb to orbit on a 100,000-km tether?

A space elevator could, in theory, haul cargo and passengers to orbit via a ground-anchored tether extending ~100,000 km, balanced by a counterweight and powered by electricity from solar or ground-based sources. It promises dramatically cheaper, cleaner access to space, but faces huge hurdles: materials stronger than anything we can currently manufacture (carbon nanotubes at requisite lengths), relentless orbital debris, and massive political and financial coordination requirements. For now it remains a visionary concept rather than an imminent reality.

SunZia’s Giant Wind Link Goes Live, Powering About a Million Homes

Electrek reports that SunZia Transmission, a 550-mile HVDC line, is now online, moving up to 3,000 MW of wind power from New Mexico to the Southwest and providing enough electricity for roughly 1 million homes; the project aims to cut about 9 million metric tons of CO2 in its first year and enhances grid resilience and efficiency for the Western grid.

SunZia Goes Online, Delivering the West’s Largest Wind Project to California

SunZia’s 916 turbines and a 550‑mile HVDC transmission line from New Mexico are now online, delivering up to 3.65 GW of wind power to Arizona and California and helping CAISO set wind-generation records, a milestone for cross‑state transmission of clean energy amid a federal tilt toward fossil fuels. The project, completed after nearly two decades and an $11 billion investment, faced environmental, cultural, and permitting challenges and is the subject of ongoing litigation.

States sue over $1B payout to TotalEnergies to quit offshore wind

A coalition of seven Northeastern states led by New York is suing the Trump administration over its nearly $1 billion payment to TotalEnergies to exit offshore wind leases, arguing the deal refunds $928 million and redirects funds to fossil-fuel investments, unlawfully pressuring a foreign company and hindering climate goals; the cancellation would affect NY’s Attentive Energy One and NJ’s Attentive Energy Two offshore wind projects, potentially powering hundreds of thousands of homes.

US clean energy booms even as policy uncertainty slows manufacturing

Q1 2026 saw 54 new large-scale renewable projects totaling more than $18 billion and adding over 12 GW of generation and storage, signaling a robust build-out as developers push to beat looming incentive changes; however, 38 projects were canceled in the period, removing about $13 billion in potential investment and thousands of jobs, highlighting policy uncertainty's chilling effect on financing—especially for EV and battery manufacturing—while grid/transmission manufacturing remains steadier and overall electricity demand climbs.
