Coal plants are draining an already dwindling global water supply, consuming enough to meet the basic needs of one billion people and deepening a worldwide crisis. Announcing its first global plant-by-plant study, Greenpeace said coal power use will increase with newly built plants, causing "huge stress" on the world's major river basins and threatening communities. In its report "The Great Water Grab: How the Coal Industry is Deepening the Global Water Crisis", released in Hong Kong, the environmental activist group urged governments to stop depending on coal, a major source of electricity and a pollutant. It highlighted Asian giants China and India as being at the forefront of the battle with their heavy use of coal. Coal plants use water at almost every step of the process, from mining and washing coal to the treatment of combustion waste, the report said. By choosing to continue huge investments in coal to power their economies for decades to come, governments would commit the world to a future of an ever more desperate fight for scarce water resources, the report said.
