The lesson of history is clear: energy transitions take a long time. Sometimes, though, the world passes a milestone that gives a sense of how the energy system is progressing. The news this week that global power generation capacity in renewable energy is greater than in coal-fired plants looked like one of those signs that the industry really is changing.
Now, capacity is one thing and generation is another. Renewables still provided only 23 per cent of the world’s power last year, well behind coal’s 39 per cent. But the data published by the International Energy Agency are a reminder that, in the words of BP chief economist Spencer Dale, “it’s possible that we will see forces leading to a faster transition coming from a number of different fronts”. He still expects wind, solar and biomass to be only 10 per cent of the world’s energy by 2035, though.
