It seems @mattwridley thinks @Telegraph readers are idiots Let's run the numbers: 244,000km2 = area of the UK 5-10% = share of UK Matt says would need to be covered with solar to meet electricity demand in June 40MW = solar capacity per km2 500-1,000GW = solar capacity, if covering 5-10% of UK 300% = share of total UK electricity demand that would be generated by 1,000GW of UK solar 650GW = current solar capacity of China, roughly half the global total <30GW = actual UK summer peak demand 15GW = current solar capacity of UK, of which ~10GW ground mounted 0.1% = current solar land take 70GW = UK govt solar target, because no one thinks we can run the country on solar alone <1% = future land take >20% = reduction in UK gas imports if govt solar target is met Zero = credibility of Matt's article
