First of all, to avoid the 2 degrees warming threshold, we need to be at net 0 emissions in like 10 years. Which absolutely requires 0% fossil fuels in electricity and heating, all year round, all over the world. 10% fossil fuels in electricity is nowhere close to good enough.

Secondly, the current best for renewables is nowhere close to 90% year round. Those 6 days in the article are a huge record for Portugal. 90% would essentially mean 330 days of exclusive renewables use, which no one in the world is close to, except maybe Iceland.
