Britain wasted £649m already this year powering down wind farms as there is not enough grid capacity to send renewable energy where it is needed, utility finds

Unlike lithium-ion batteries, vanadium flow batteries use electrolyte solutions containing vanadium ions to store and release energy. The technology offers a number of advantages for grid-scale storage: high safety (non-flammable), long cycle life (over 15 years), and the ability to decouple power and energy capacity, offering greater design flexibility.

Some key insights from the article:

Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.

Australian-based renewable energy and storage investor Quinbrook Infrastructure Partners says its new 373 MW Cleve Hill Solar Park – the biggest in the UK – has begun commercial operations.

The Cleve Hill solar park, situated in Kent in England’s south, consists of over 550,000 solar panels and is expected to provide clean electricity equivalent to the needs of 102,000 homes, and is being hailed as a landmark on multiple fronts.

It is four times the size of the next largest operational UK solar project, and will also feature a 150 MW co-located battery energy storage system (BESS), making it also the largest co-located solar plus storage project ever constructed in the UK power market.

Cleve Hill was also the first solar and battery storage project to be consented as a Nationally Significant Infrastructure Project (NSIP) by the UK government, and secured the first solar contract for difference (CfD) by the UK Government-backed Low Carbon Contracts Company.

"This is not a transition. It’s a systematic expansion of all energy sources.”

Most countries in BRICS, which includes Brazil, Russia, India, China and South Africa, remain major fossil fuel producers, but the group together produced 51% of the world’s solar energy in 2024 — up from 15% a decade earlier, energy research firm Ember said in the report.

Serra Verde’s licence, granted by the state in 2019 to explore rare earths, was met with enthusiasm locally.

Serra Verde claims to be a “sustainable” mining company,

Residents living near the mine are nonetheless concerned about the potential environmental effects. Families report that since mining began, two streams in Serra Verde have become muddy, with a greasy substance turning clear water a reddish colour. They also reported miscarriages in cattle drinking water from the same source.

Maintaining a positive image in Brazil is crucial for the company as it seeks to differentiate itself from those mining in Asia, where problems have already been identified in the extraction of rare earths.

Residents such as Lima believe life mining rare earths will bring no greater prosperity to for most than when they lived with asbestos. “These rare earths are now the same,” he says.

When the design, manufacturing, and service of a piece of equipment, whether it’s a platform, lifting device, seal system, or shielding assembly, are handled by separate parties, accountability can become unclear. If an issue arises or a field modification is required on short notice, it’s not always obvious who owns the resolution. Project teams can find themselves stuck between vendors, each deferring responsibility to another, while the work halts and outage time extends.

• Argentina is trying to position itself as a global hub for clean energy, attracting private investment in lithium mining while marketing new battery factories in the region.
• The World Bank has framed some of the lithium projects it backs as “climate action” that will help advance the clean energy transition.
• But critics say lithium mining is hurting local and Indigenous communities and depleting freshwater resources.
• The race to buy up private land for lithium mining has also allowed an influx of international corporations that may contribute to increased carbon emissions rather than help lower them, critics point out.

Critics of the 'green transition' argue it is imposing an unacceptable cost on ordinary working people. But is it really renewable technologies that are causing our bills to go up, or are there other forces involved? We scratch the surface and take a look.

Imagine this. You’re living in a remote rural hamlet in the forested hills of Mysore, in the southern Indian state of Karnataka. You’re miles from the nearest doctor, a day’s journey by foot and bus to the nearest hospital. And there’s no mains electricity. If you suddenly fall ill and need urgent medical help, what are your chances?

A few years ago, they’d be slim. Today, though, you make your way a couple of hundred metres down the track to a minor miracle: a small, gleaming white building topped with solar panels. Inside, a specially trained health worker checks you out, runs a few tests, takes your blood pressure, even does an ECG, maybe gives you some lifesaving treatment or medicine. Then she connects you to a doctor in a distant hospital, who’s right there on the screen, giving you the sort of specialist consultation that would normally be far out of reach.

It sounds like one of those rosy scenarios beloved of futurists, but this isn’t speculative fiction. The Climate Smart Health Clinic, as the sign over the door declares, is here and now, in the village of Basavanagiri Hadi.

It’s part of an ambitious programme that is using a combination of solar power and mobile connectivity to revolutionise the prospects for healthcare across swathes of rural India. It springs from the Selco Foundation, an independent not-for-profit, which is a sister organisation of Selco India, the country’s leading solar company specialising in small-scale, decentralised systems.

With the backing of the Ikea Foundation, the scheme is designed to provide reliable, clean and affordable electricity to 25,000 of the country’s state-run primary health care (PHC) centres, as well as to explore entirely new ways of delivering health services – like the ‘tele-clinic’ in this Mysore village.

LG Energy Solution’s new lithium-iron phosphate (LFP) battery plant in Holland, Michigan, marks a significant step for clean energy in the US. Opened in early May 2025, this facility shifts focus from electric vehicles (EVs) to energy storage systems (ESS) as EV demand cools. This article explores the plant’s impact on jobs, the economy, clean energy, and how policies like the Inflation Reduction Act (IRA), the One Big Beautiful Bill, tariffs, and competitors shape its future.

On a vast property in Lee County, in the heart of southwest Georgia, Tyler Huber raises sheep.

As the flock grazes, the sheep need somewhere to take a break from the Georgia sun.

“It is incredibly hot, the sun is just unavoidable, and the fact that they’ve got shade every fifteen feet out here — it’s just the ideal environment, to have shade so close,” he said on a recent hot day.

The shade comes from solar panels, using that same relentless sunshine to generate energy. The sheep, in turn, cut down on mowing costs for the solar farm. The flock loves chowing down on the vegetation under and around the panels, Huber said.

Before solar developer Silicon Ranch bought this land, it used to have row crops — mostly corn and cotton — and beehives. Farmers can’t grow corn and cotton under solar panels, but this is still farmland for sheep and bees.

Scenes like this are increasingly common as power companies add more and more solar energy to keep up with rising demand for renewable electricity. Many of those solar panels are being built on farmland. The American Farmland Trust, which tracks the conversion of farmland to other uses, projects that 80 percent of the acreage needed to scale up solar energy could be agricultural land. The trend has given rise to a wave of opposition from local activists to state legislatures and the White House.

The newest, hottest power couple doesn’t live in Hollywood. It’s actually the marriage of solar panels and water reservoirs: Known as floating photovoltaics, or floatovoltaics, the devices bob on simple floats, generating power while providing shade that reduces evaporation.

One primary advantage of the technology is that you don’t have to clear trees to make way for solar farms. As an added bonus, the water cools the panels, increasing their efficiency. Research has shown that if societies deployed floatovoltaics in just a fraction of the lakes and reservoirs of the world, they could generate nearly a third of the amount of electricity that the United States uses in a year.

As floatovoltaic systems rapidly proliferate — the market is expected to grow an average of 23 percent each year between 2025 and 2030 — scientists are investigating how the technology might influence ecosystems. The shading, for instance, might stunt the growth of algae that some species eat — but at the same time, it might also prevent the growth of toxic algae. The floats might prevent waterbirds from landing — but also might provide habitat for them to hide from predators. By better understanding these dynamics, scientists say that if companies are willing, they can work with manufacturers to customize floatovoltaics to produce as much electricity as possible while also benefiting wildlife as much as possible.

“Renewable energy, low-carbon electricity, is a really good thing for us, but we shouldn’t be expanding it at the cost of biodiversity loss,” said Elliott Steele, a postdoctoral researcher at the University of California, Davis, and co-author of a recent paper about floatovoltaics and conservation in the journal Nature Water. “This is a great opportunity for us to increase our research and develop smart design ideas and better siting practices in order to have this happy marriage between a healthy, biodiverse ecosystem and renewable energy expansion.”
