Can AI Help Fight Climate Change – or Is It Making Things Worse?


Can AI Help Fight Climate Change – or Is It Making Things Worse?

Artificial Intelligence is everywhere at the moment – from writing essays to spotting cancer, from traffic control to climate modelling. But a perfectly reasonable question keeps coming up:

Is AI part of the solution to climate change – or is it quietly making the problem worse?

As with most environmental questions, the honest answer is: it depends how we use it.

🌱 How AI Can Help with Climate Change

Used well, AI is an extremely powerful tool for reducing emissions and waste.

🔍 Better climate science

AI can process vast datasets far faster than humans:

  • More accurate climate models

  • Improved weather and flood forecasting

  • Better understanding of tipping points

This helps governments and planners prepare, adapt, and act earlier.

⚡ Smarter energy systems

AI is already being used to:

  • Balance renewable energy on the grid

  • Predict electricity demand

  • Optimise battery storage and charging

That matters hugely as homes move to heat pumps, solar panels, and EVs.

🏭 Cutting industrial waste

In factories, AI can:

  • Optimise manufacturing processes

  • Reduce scrap and energy use

  • Spot inefficiencies humans miss

Small percentage gains here add up to massive carbon savings.

🌾 Farming with fewer inputs

AI-powered tools can:

  • Reduce fertiliser and pesticide use

  • Optimise irrigation

  • Predict crop disease earlier

Less waste, less runoff, lower emissions.

⚠️ The Environmental Cost of AI

Here’s the uncomfortable bit.

🖥️ Energy-hungry data centres

Training large AI models requires enormous computing power, often running for weeks:

  • Huge electricity demand

  • Still partly powered by fossil fuels in many regions

If the grid isn’t green, neither is the AI.

💧 Water use for cooling

Many data centres use millions of litres of water each year for cooling:

  • A real issue in drought-prone areas

  • Often invisible to users typing prompts at home

🧠 Rising hardware demand

AI has driven:

  • Increased demand for high-end GPUs

  • Shortages of chips and memory

  • Higher prices for researchers, educators, and small businesses

There’s also a hidden environmental cost in mining rare metals and electronic waste.

⚖️ So… Net Positive or Net Negative?

Right now?

👉 AI is neither automatically green nor automatically harmful.

It becomes:

  • A climate ally when used to reduce emissions, improve efficiency, and accelerate clean energy

  • A climate liability when used carelessly, endlessly scaled, and powered by dirty energy

In other words:

AI reflects our choices – not our intentions.

🛠️ What Needs to Happen Next

To make AI genuinely climate-positive, we need:

  • ✅ Data centres powered by renewables

  • ✅ Transparency about energy and water use

  • ✅ Smaller, more efficient models where possible

  • ✅ Using AI to replace wasteful systems, not just add new ones

Efficiency must become a design goal – not an afterthought.

🌍 Final Thought

AI won’t save the planet on its own.
But neither will banning it or pretending it’s the villain.

Like most powerful tools, AI can help fix climate change – if we make it do so deliberately.

The real question isn’t “Is AI green?”
It’s “Are we?”

New Filtration Technology Could Be a Game-Changer in Removing PFAS “Forever Chemicals”

New Filtration Technology Could Be a Game-Changer in Removing PFAS “Forever Chemicals”  PFAS – often called “forever chemicals” – have a nasty habit of doing exactly what their nickname suggests: they don’t break down , they build up in the environment, and they accumulate in our bodies. Used for decades in non-stick cookware, waterproof clothing, firefighting foams, food packaging and industrial processes, PFAS are now found in rivers, groundwater, drinking water – and even rain . The scale of the problem has felt overwhelming. Until now. A breakthrough from the lab Researchers at Rice University have developed a new filtration material that could dramatically change how we deal with PFAS pollution. Their peer-reviewed research describes a layered double hydroxide (LDH) material made from copper and aluminium that can: Absorb long-chain PFAS up to 100× faster than current filtration systems Target the most persistent and dangerous PFAS compounds Potentially destr...

Using Ecosia: The Search Engine That Plants Trees

  Using Ecosia: The Search Engine That Plants Trees ( Click. Search. Plant. Repeat. ) Imagine if every time you googled something, you planted a tree. No, it’s not some kind of green-tech fantasy — it’s Ecosia , a real search engine that uses its ad revenue to fund global reforestation projects. And all it takes is changing your browser’s homepage. What Is Ecosia? Ecosia is a free, privacy-respecting search engine based in Germany. It works just like Google or Bing, but with a twist: They use 100% of their profits to plant trees. So far, they've funded over 180 million trees in places like: Brazil Burkina Faso Madagascar Indonesia Kenya All you have to do is search the web. That’s it. You search — they plant. How It Works Every time you search on Ecosia, the platform earns revenue from clicks on sponsored search results (just like Google). Roughly 45 searches = 1 tree . The money goes to vetted reforestation projects with a focus on: Native bi...

Insulation: Can You Ever Have Enough?

Image
  Insulation: Can You Ever Have Enough ? Short answer: almost certainly not . Longer answer: many UK homes have some insulation, but far fewer have the right amount, in the right places, installed to modern standards . This blog looks at the crucial difference between what you have and what you should have – and why that gap matters for your comfort, bills, and carbon footprint. What Most Homes Have If your house was built before the 2000s, typical insulation looks like this: 🏠 Loft 100–150 mm of mineral wool Often patchy, compressed, or missing at the edges 🧱 Walls Cavity walls : may have older blown insulation (or none at all) Solid walls (common pre-1920): usually uninsulated 🪵 Floors Timber floors with no insulation underneath Draughts coming up through gaps you only notice in winter 🚪 Windows & doors Double glazing, but with: Poor seals Thermal bridges around frames This setup was once considered “reasonable”.
