A  team of scientists say they can predict attacks and blackouts, making the grid more resilient –– and they are using AI.

In a bold move toward sustainability, CIÉ, Ireland’s national public transport provider, has pledged to install solar panels on the rooftops of all its...

Germany is cutting its dependence on Chinese wind turbine components by 2035, launching a major strategy to diversify its offshore wind supply chain. As Europe ramps up clean tech investments, this move marks a shift toward energy security and regional manufacturing resilience.

Asia continues to dominate global renewable energy growth, accounting for 71% of new capacity added in 2024, while Africa and other developing regions remain far behind despite their potential. Solar and wind lead the charge, comprising 97.5% of additions, with solar alone adding 453 GW. Although global renewables capacity hit a record 582 GW, the world is still off track to meet the COP28 goal of tripling capacity by 2030. Without faster growth and more equitable investment, the energy transition risks deepening the global divide.

In a dramatic reversal, President Donald Trump has lifted a federal stop-work order on the $5 billion Empire Wind project off the coast of...

Martin Varsavsky, a seasoned entrepreneur behind billion-dollar clean energy exits, says he’s lost faith in the renewable energy paradigm. Moshe Luz, director at Ivanpah, the world’s largest solar thermal power tower project in California’s Mojave Desert, believes just the opposite.

As of 2025, the US solar industry is attracting tens of billions of dollars in private investment. That kind of capital signals more than just market growth—it signals disruption. And nothing screams disruption quite like solar paint: a substance that can generate electricity, just like a solar panel, but goes on like regular paint.

On April 28, 2025, Spain and Portugal experienced a massive power outage that disrupted daily life for tens of millions. The blackout, which began around 12:30 p.m., led to halted transportation, communication failures, and significant economic losses. This event has sparked a critical examination of the challenges associated with the integration of renewable energy sources into national power grids.​

Green PE is produced using ethanol derived from renewable sources—primarily sugarcane in Brazil, but also wheat grain and beet in Europe. It behaves the same as traditional polyethylene: it’s durable, moldable, and recyclable. The difference lies in its feedstock and carbon footprint. While not biodegradable, Green PE is a key player in the circular economy: it sequesters carbon during crop growth and reduces life-cycle emissions when used and recycled responsibly.

Helion’s model plays to America's old strength: innovation through agility, not top-down megaprojects. Instead of waiting for 2050, Helion’s compact reactors aim to deliver electricity in a matter of years—and not just for cities, but for data centers, isolated industries, military bases, even disaster zones. Their current prototype, Polaris, is scheduled to fire in 2025. If Helion succeeds, it won’t just disrupt global energy. It could redraw the world map.

“We are building an advanced elastocaloric device that can replace today's harmful cooling systems and have a measurable impact on climate goals,” Tušek says.

In the misty folds of the French Pyrenees, something quietly extraordinary is happening. At a remote site called Comminges in France, Mantle8, a pioneering natural hydrogen exploration company, has unearthed a breakthrough that could shift the balance of Europe’s energy landscape.

A Cornell-led collaboration has achieved a breakthrough in sustainability technology by developing a low-cost method for producing carbon-free “green” hydrogen via solar-powered electrolysis of seawater. An added benefit of this process? Potable water.

The US Supreme Court made a landmark decision this week by dismissing a challenge from 19 Republican-led states. This ruling allowed five Democratic-led states to continue their lawsuits against major oil companies, including Exxon, Chevron, ConocoPhillips, Shell, and BP. These lawsuits accuse the oil giants of misleading the public about the environmental impacts of fossil fuels, particularly with regard to climate change.

A little-known $15 billion deal between PG&E and the Department of Energy is raising concerns for California residents. The agreement, which will expand hydropower, also includes shutting down the Ivanpah solar plant, which has been providing energy to 140,000 homes. Without this reliable source of clean energy, California's already overburdened power grid will struggle, leading to higher energy costs and more frequent blackouts. Critics argue that while PG&E benefits financially, everyday Californians will be left paying the price with increased bills and an even less reliable power system. Questions are also being raised about possible conflicts of interest with key players in the deal, making it even more controversial. We spoke with one of the main investors of the Ivanpah plant to learn more.
