The big problem with solar energy is that it is not reliable.
A quick look at Germany and few other European countries' solar production, today Feb 2nd. (Source:

Germany: 7.5% of installed capacity
Denmark: 24.11%
The Netherlands: 14.15%
Won't installing windmills work as a backup? Nope, wind can perform poorly at the same time as solar is performing badly.
Germany: 11.81% of installed capacity
Denmark: 4.45%
The Netherlands: 37.9%
Sweden: 12.54%
Solar & Wind perform well on a yearly basis, but that doesn't help those days when it is cloudy and there is little wind meaning that a considerable number of backup fossil powered plants must be maintained which is costly and not very environmentally friendly.
It is madness scrapping nuclear power which is a reliable and relatively environmentally friendly power source.
