Indonesia still relies on coal in race to cash in on EV boom

Even a decree passed last year to promote renewable energy (RE) and stop new coal power makes an exception for offgrid plants at "national strategic" projects, allowing them to operate until midcentury. Indonesia's hefty bet on metal processing has brought billions of investment dollars and tangible growth in export value.
