'Unstoppable force' of solar power propels world to 40% clean electricity

And yet sometimes I wonder. In the Uk you need most of your energy in the cold dark winter. So if you require enough non solar renewables to get you through the winter with net zero and those renewables are still available in the summer time are large scale solar not a bit redundant? Sunnier countries that have high electricity demand for air conditioning during the sunny periods would seem to have a better match mind.

It's usually windy when it's dark and cold and vice versa.

You should be wondering about the combination of solar + wind energy + short term storage + long term storage.

Usually, but not always. You can have many days or weeks, e.g. in mid-winter of overcast weather and very little wind. This is a real problem for renewable energy sources, they're not comprehensively viable unless supplemented by alternatives like gas peakers or perhaps nuclear.

Or geographic interconnection. There hasn't been an hour in the past 30 years where there was no wind or sun somewhere in Europe.
