Wow, what a fantastic feat! With the extra solar and wind capacity built over the last 12 months, records have been tumbling on a weekly basis for renewable energy generation. This is truly the biggest achievement though as renewables have met half of our electricity demand. Donald Trump pulling the USA out of the Paris Climate Change Agreement is clearly going to be a very minor blip as we can see that renewables aren't just a nice to have but they are now the cheapest way of producing electricity in the majority of the world. It is clear that the transition to a low carbon energy future has gained sufficient momentum and cannot now be stopped.
