I am a huge proponent of renewables, but you cannot compare their capacity in GW with other energy sources because their output is variable and not always maximal. To realistically get 100GW in solar you would need at least 500GW of panels.
On the other hand, I think we will not actually need 100GW of new installations because capacity can be acquired by reducing current usage by making it more efficient. The term negawatt comes to mind. A lot of people are still in the stone age when it comes to this even though it was demonstrated quite effectively by reduced gas use in the US after the oil crisis in the 70s. Which basically recovered to the pre crisis levels only recently.
High gas prices caused people to use less and favor efficiency. The same thing will happen with electricity and we'll get more capacity. Let the market work.
