It is now cheaper to generate electricity from new renewables than from new coal-fired power stations in all major energy markets across the world,according to a report from the think tank Carbon Tracker.And,by 2030 at the latest,the data suggests it will be cheaper to build new wind or solar capacity than to continue operating coal at all.Analysts at Carbon Tracker looked at the economics of 95% of coal plants that are either operating,under construction or planned across the world.Some 6,700 units totalling 2,050 GW are currently running and 1,050 units(500 GW)are in various stages of the development pipeline.The total cost of all planned coal plants is nearly $640bn.Carbon Tracker has warned that governments and investors may never recover their investments in these facilities,as it can take 15 to 20 years to recoup construction costs.
