Exciting developments in solar.

Just read this fascinating FT article on perovskite solar panels – the next-gen innovation that's lighter, more flexible, and up to 20% more efficient than traditional silicon ones.

Imagine panels turning everyday surfaces into power generators

Energy efficiency needs a radical rethink.

Making fossil fuel technologies & processes incrementally more efficient is no longer enough.

It might even perpetuate their use. In my new article I explore how energy efficiency needs to evolve to remain relevant.

Why energy efficiency needs a radical rethink

Energy efficiency has historically been the most significant contributor to reducing greenhouse gas emissions. Over the past few decades…

No surprise - the North Sea continues to erode the coast in front of the Sizewell C site & now appears to be less than 20 metres from the site boundary where the temporary sea defences are being constructed. Sizewell C - a #climatechange casualty, not a solution

A wonderful turnout to celebrate saving these 8 precious oaks from the Sizewell C chainsaws. Huge thanks to Mandy Beaumont who ran such a successful campaign on behalf of the surrounding villages to stop the needless destruction of such valuable wildlife habitat by Sizewell C

Absolutely weird formulation, and part of the much broader problem of the idea that a single new chunk of load can be linked physically to a single chunk of supply, on a distributed and massive power grid.

Also see: "We need nuclear / gas for our data centre because reliable baseload power" etc

Sprawling solar farms, windmills and hydroelectric dams are the best energy options for the planet, and usually the cheapest. Their economic upside has made them, collectively, the fastest-growing power source for data centers worldwide.

But renewables often can’t shoulder the load alone, despite being a major part of the A.I. power plan. That’s because servers hum and whir around the clock — not just when the sun is up or the wind is blowing. They demand a constant, stable flow of electricity. If power falters, even for a few seconds, companies lose thousands of dollars, sometimes more.

The irony of yet another carbon credit scheme in the Amazon (rainforest), which Amazon (company) hoped to use to offset its emissions, falling apart.

This time it’s cuz the scheme ran afoul of laws protecting the rights of Indigenous peoples.

Brazilian prosecutors seek to block $180 million carbon credit deal

Brazilian prosecutors are seeking to annul a $180 million carbon offset scheme to support the conservation of the Amazon rainforest that the state of Para signed last year with a coalition of major corporations and wealthy governments, according to a complaint filed on Tuesday.

Steel is the backbone of Britain's industry—and British steel is central to the Green Industrial Revolution we need.

Today I backed the Steel Industry (Special Measures) Bill and made the case for public ownership, more recycling of scrap steel, fair electricity prices, and support for innovation.
