Japan's Isogo power station uses 2 million tonnes of Australian coal every year, accounting for 75% of its total coal usage. There is debate around building new high-efficiency, low-emissions (HELE) coal power stations in Australia. Supporters argue it could provide reliable base load power at a lower cost than renewables. Critics argue that even HELE coal produces carbon emissions and renewable energy is now cheaper to build with no fuel costs. Politicians and industry groups disagree on the best approach for Australia's energy mix and reducing emissions.
