The Greenest Energy Is the Energy You Never Use

Image
  The Greenest Energy Is the Energy You Never Use For years, the conversation around “going green” has focused on generating more energy. More solar panels. More wind turbines. More batteries. More electric cars. And yes — we absolutely need all of those things. But after years of experimenting with our own house, I’ve come to a slightly uncomfortable conclusion: The biggest environmental gains often come from simply using less energy in the first place. Not through misery. Not by sitting in the dark wearing three jumpers. But by wasting less. And strangely enough, that is often the part people ignore. The Big Surprise Our home now has: 26 solar panels Around 50kW of battery storage A heat pump Very good insulation Solar hot water Electric-powered boating equipment A house full of cameras, computers, lighting, and studio equipment People assume the biggest change came from adding more solar panels. It didn’t. The biggest improvement came from reduc...

Electric Cars Are Brilliant… So Why Haven’t I Bought One Yet?

  Electric Cars Are Brilliant… So Why Haven’t I Bought One Yet? The Transport Reality Check Nobody Really Talks About I like electric cars. Actually, I like them a lot. Quiet. Smooth. Efficient. Instantly responsive. And when charged from renewable energy, they make an enormous amount of environmental sense. So why haven’t I bought one yet? That’s where things get more complicated. The Ideal vs The Reality On paper, I should already own one. We already have: Solar panels Battery storage An increasingly electric household In theory, an EV would fit perfectly. And yet… The numbers still matter. A decent electric car is still expensive. Very expensive in many cases. And when your current vehicle still works perfectly well, replacing it purely for environmental reasons becomes a much harder financial decision. That’s the uncomfortable reality many people are quietly facing. The Cost Barrier Is Real Electric cars are improving rapidly. But: Purchase prices remain high Insurance can be e...

7 Changes at Home That Actually Reduce Energy Use

  7 Changes at Home That Actually Reduce Energy Use Real Results, Not Just Good Intentions After years of experimenting (and a fair bit of trial and error), I’ve come to a slightly uncomfortable conclusion: There is no single “magic upgrade.” No silver bullet. No one device that suddenly makes everything efficient and cheap. Instead, it’s a combination of small, well-chosen changes—working together—that really make the difference. Here are seven that genuinely do. 1. Use Energy When You Generate It If you have solar panels, timing matters more than you think. Using electricity: During the day When the sun is shining means you’re using your own energy rather than buying it from the grid. Simple shifts like: Running the washing machine at midday Charging devices in daylight Heating water when solar output is high  can dramatically reduce grid reliance. Think of it like sailing—you don’t fight the wind, you use it. 2. Battery Storage Changes Everything If solar is generation, bat...

Is Carbon Capture a Solution… or a Delay?

Image
  Is Carbon Capture a Solution… or a Delay? The Climate Fix That Might Be Buying Us Time… or Costing It Carbon capture sounds brilliant on paper. Capture missions. Store them underground. Carry on as before. Problem solved. If only it were that simple. What Is Carbon Capture, Really? Carbon Capture and Storage (CCS) is exactly what it sounds like: Capture CO₂ from power stations or industry Compress it Inject it deep underground for long-term storage In theory, it allows us to keep using fossil fuels—or biomass—without releasing emissions into the atmosphere. And that’s why it’s so appealing. It promises change without disruption . The Timing Problem Here’s where things get uncomfortable. Some approaches—especially bioenergy with carbon capture (BECCS) —rely on: Growing biomass (trees or crops) Burning it for energy Capturing the resulting CO₂ Sounds carbon neutral… even carbon negative. But recent research suggests: It can take decades—or even over a century to truly offset the c...

AI Is Booming… But Can We Afford Its Energy Appetite?

  AI Is Booming… But Can We Afford Its Energy Appetite? Smarter Technology, Bigger Energy Question Artificial Intelligence is everywhere. Helping us write. Plan. Analyse. Even generate entire blogs like this one (ironically). It feels efficient. Invisible. Almost weightless. But behind the scenes, there’s something we don’t often talk about: Energy. A lot of it. The Hidden Infrastructure Behind AI Every AI prompt, every generated image, every automated system runs through vast networks of servers housed in data centres. These aren’t small rooms with a few computers. They are: Warehouse-sized buildings Packed with high-performance processors Running 24/7 Constantly cooled to prevent overheating And cooling alone can consume a significant proportion of total energy use . According to the International Energy Agency , energy demand from data centres is rising faster than almost any other sector. Let that sink in for a moment. Faster than transport. Faster than ...
