<p><strong>Here is a brief summary of how the UK power grid transformed between the 2000s and 2020s:</strong></p>
<ul>
<li><strong>Coal Collapsed:</strong> Dropped massively from nearly a third of all power (32.5%) to just 1.3%.</li>
<li><strong>Wind Surged:</strong> Exploded from under 1% to 24.4%, replacing coal as the second-largest energy source.</li>
<li><strong>Other Renewables Jumped:</strong> Solar and biomass saw major gains, growing from a combined 2% to over 16%.</li>
<li><strong>Gas Remained #1:</strong> Natural gas is still the primary power source, but its share dipped from 39% to 33%.</li>
<li><strong>Nuclear Declined:</strong> Dropped from 19.4% to 13.5%.</li>
</ul>
<p>In short: The UK went from a heavily fossil-fuel-reliant grid (over 70% coal and gas) to a much greener, diverse system powered largely by gas, wind, and nuclear.</p>
