It is hard for humans to work with exponential curves. Solar went from 15 cents per kwh to 5 cents per kwh over the last 10 years.

Anticipating such a rapid decline is hard and a lot of people still are stuck on outdated data.

Sure China commissioned these plants in the past and will plan more, but it won't be due to cost.

But you don't need to work with exponential curves to know that you can use solar only for like half a day and even less during winter. Those solar installation now are big part of overall cost. And with majority of EU population living in flats where you gonna install them?
