By Mai Nguyen SINGAPORE, Nov 23 (Reuters) - The Russia-Ukraine war has quickened countries' transition to renewable energy, underpinning current and future demand for copper, a company executive at global miner Anglo American PLC AAL.L said on Wednesday. "Everything we talk about in terms of energy transition is about copper," Anglo American's CEO of Base Metals Ruben Fernandes told Reuters in an interview. Fernandes expected inflation generally to have peaked, but said the industry still faced uncertainty over the Russia-Ukraine war and the COVID-19 pandemic.
