Trump’s Shock Attack on Offshore Wind – Permit Reversal Threatens Massive Massachusetts Wind Farm

Trump’s Shock Attack on Offshore Wind – Permit Reversal Threatens Massive Massachusetts Wind Farm

President Donald Trump’s administration has moved to block a fully permitted offshore wind farm off the Massachusetts coast by seeking to revoke its key federal permit abcnews.go.com. The project – known as SouthCoast Wind – calls for 141 turbines about 23 miles south of Nantucket to power roughly 840,000 homes across New England abcnews.go.com. Approved in January 2025 after years of review, its construction was poised to begin – until Trump’s team abruptly intervened. This unprecedented attempt to “take back” the wind farm’s permit marks the latest salvo in a broader campaign by Trump to hobble offshore wind development abcnews.go.com.

Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source

Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source

What Is Osmotic Power and How Does It Work? Osmotic power (or salinity gradient energy) is electricity generated from the natural process of osmosis – the movement of water across a membrane from a dilute solution to a salty solution theguardian.com. At river deltas where freshwater meets the ocean, immense chemical energy is continuously released as the two mix. Osmotic power plants capture a portion of this energy by separating fresh and salt water with special membranes in a controlled setting theguardian.com. The concept has been studied since at least the 1970s, but only in recent years have technological advances

PEM vs Alkaline vs Solid Oxide Electrolyzers: The 2025 Hydrogen Technology Showdown

PEM vs Alkaline vs Solid Oxide Electrolyzers: The 2025 Hydrogen Technology Showdown

Alkaline electrolyzers use a liquid potassium hydroxide (KOH) electrolyte, operate at about 60–80 °C, and have decades of industrial use in chlor-alkali and fertilizer plants. PEM electrolyzers use a solid polymer membrane and typically operate at 50–80 °C, delivering very high-purity hydrogen (>99.999%), with iridium catalysts at the anode and platinum at the cathode. SOEC operate at 700–850 °C with a ceramic oxide-ion electrolyte, reduce steam to hydrogen, and can exceed 80% LHV electrical efficiency when heat is supplied, with Sunfire achieving about 84% LHV in a multi‑megawatt unit and NASA reporting a 4 MW SOEC system in 2023.

Solar Tech Showdown 2025: N-Type TOPCon vs HJT vs Perovskite Tandem – Which Will Power the Future?

Solar Tech Showdown 2025: N-Type TOPCon vs HJT vs Perovskite Tandem – Which Will Power the Future?

As of mid-2025, commercial N-type TOPCon cells reach about 23–24% efficiency, with best mass-produced TOPCon modules at 23.8% and JinkoSolar reporting 26.4% cell efficiency in tests. Heterojunction (HJT) solar cells regularly reach 25%+ efficiency in production, with Longi reporting a 27.3% lab cell efficiency. Perovskite–silicon tandem cells have surpassed 33% efficiency in labs (Longi 33.9%, KAUST 33.7%), and Oxford PV has a 72-cell tandem module at 24.5%. TOPCon modules typically retain about 87–90% of their power after 25–30 years, with a 3-year desert test showing just 0.14% degradation. HJT modules are generally stable, but a desert field study found HJT

Your Next Rooftop Will Be a Power Plant. Rooftop Energy Technologies: Present and Future Innovations.

Solar PV costs have fallen about 90% over the last decade. Modern home solar panels often exceed 20% efficiency, with typical residential systems of 5–10 kW. In the United States, over 4 million homes had solar panels by early 2024. Global rooftop PV adoption could reach about 100 million households by 2030. In the United States, the rooftop solar roofing market is projected to reach nearly $1 billion by 2025, as California mandates solar on almost all new homes starting in 2023. A Dutch startup unveiled the Blade X1 rooftop wind turbine at 1.4 meters tall, generating about 2,500–3,000 kWh

This New Solar Panel Tech Works Even at Night

This New Solar Panel Tech Works Even at Night

Thermoradiative energy generation, nicknamed night-time solar, produces electricity by emitting infrared radiation to the cold night sky when the device is warmer than its surroundings. Unlike conventional solar cells that absorb sunlight, thermoradiative devices emit photons to space, effectively running as a solar cell in reverse and using the Earth–space temperature difference at night. In 2020, Jeremy Munday and colleagues proposed an anti-solar cell that could theoretically produce up to about 50 W/m² at night under ideal conditions. In 2022, UNSW Sydney demonstrated the first unambiguous lab power from a thermoradiative diode using mercury cadmium telluride (HgCdTe), generating nanowatts and

Renewable Revolution 2025: Game-Changing Innovations in Solar, Wind, Geothermal, Bioenergy & Hydropower

Renewable Revolution 2025: Game-Changing Innovations in Solar, Wind, Geothermal, Bioenergy & Hydropower

Perovskite-silicon tandem solar cells achieved about 29% efficiency on commercial-size cells, exceeding traditional silicon panels. Bifacial solar panels boost energy yields by up to 30% in reflective environments such as snow or sand. Floating solar farms can raise output by roughly 15% due to water cooling of the panels. Covering 10% of the world’s reservoirs with floating solar could yield about 20 TW of capacity, roughly 20 times today’s global solar capacity. Offshore wind turbines now reach 15–18 MW per turbine, enabling major capacity gains in deep waters. Floating offshore wind pilots have been launched by Norway, France, and Japan,

1MW vs 100kW Solar Power Plants – Cost, ROI & Global Insights (India in Focus)

1MW vs 100kW Solar Power Plants – Cost, ROI & Global Insights (India in Focus)

100 kW solar plants typically use about 250 panels of ~400 W each, cover roughly 600–1,000 m², and generate about 150,000–175,000 kWh per year, enough to serve 15–30 homes. 1 MW solar farms deploy about 2,500 panels of ~400 W each, require ~16,000–20,000 m² (4–5 acres) of land, and produce around 1,600,000–1,800,000 kWh annually, enough for about 150–200 homes. In India, a 100 kW system costs about ₹50–80 lakh (₹0.5–0.8 crore) and a 1 MW system about ₹4–5 crore, roughly ₹60–₹80/W for 100 kW versus ₹40–₹50/W for 1 MW. India’s LCOE estimates place 100 kW at roughly ₹3–5/kWh and 1

Beaming the Watts Down: NASA × Ascent Solar’s Thin-Film Array Sets the Stage for Space-to-Earth Power Transmission

Beaming the Watts Down: NASA × Ascent Solar’s Thin-Film Array Sets the Stage for Space-to-Earth Power Transmission

The space-based solar power (SBSP) concept was proposed in 1968 by Peter Glaser to place satellites in orbit and beam power to Earth. In 2023 Caltech’s Space Solar Power Demonstrator (SSPD-1) conducted three beaming tests in May, June, and July 2023 using the MAPLE flexible array to show ground reception of orbital power. In June 2025, Ascent Solar announced a 12-month Collaborative Agreement with NASA’s Marshall Space Flight Center (MSFC) and Glenn Research Center (GRC) to develop thin-film PV arrays for power beaming. Ascent’s copper-indium-gallium-selenide (CIGS) thin-film modules achieve about 15.7% production efficiency, with the Titan line targeting 17%+ efficiency
