🔥 What Happens When the Wind Stops?
On a cold, still January night in 2021, something worrying happened across the UK. The wind turbines slowed. Solar panels produced nothing — it was dark. Gas power stations had to race to fill the gap. It worked that night. But it raised a question every energy planner has to answer: what do we do when our renewable sources stop generating?
Britain's energy mix has changed radically in the last 20 years. In 2010, coal provided around 28% of our electricity. By 2023 it was close to zero. Offshore wind, solar, and nuclear have grown enormously. But switching from reliable, always-on fossil fuels to intermittent renewables creates a new kind of challenge — and a new kind of urgency. Understanding where our energy comes from, how reliable it is, and what it costs the environment is one of the most important real-world applications of physics.
