Completely wrong. Renewables plus battery storage and long-distance transmission lines can potentially solve the power generation problem, although we're decades away from being able to scale that up in a way that addresses base load requirements for heavy industry in an economical way. But beyond power generation, natural gas is a crucial feedstock for the chemicals industry. Renewables won't solve that and the German chemical manufacturing industry is dying.
Many people only look at "electricity" generation when they think about renewables, but fail to recognize that that is only part of energy consumption (and a surprisingly small one at that). Globally electricity production only accounts for ~21% of energy usage, so even if we had an entirely green grid across the entire planet we still would have a long way to go as far as having sustainable energy usage.
