Renewables lead to energy independence and a more distributed energy grid. It's fundamental to security, and can't be so easily measured in terms of money. The EU is increasing its independence from China via initiatives like the Net-Zero Industry Act. And this talk of "politicians being bought by Chinese companies" is laughable in the face of what oil companies are doing, to the benefit of exporters like USA, Russia, Saudi Arabia, and other regimes, and definitively not the EU.
