It's not black and white. Renewable energy is better than burning oil, agreed.
But i.e. there is no recycling process for old wind turbines (carbon fiber) - they need to be replaced after 30 years or solar panels (composite material). And e-cars need batteries which need lithium (mines). Also rare earths are needed for generators and electric motors - rare earths are... rare and the production requires lots of energy and produces toxic waste (in China... which has kind of a monopoly on it. )
Maybe solvable problems in the long run but currently these are unsolved issues...
There's a massive amount of ongoing research into lithium-free batteries. Sodium-ion has gotten a big boost recently and real solid-state batteries are starting to see commercialization.
