From comments – “6kW PV system with 4kWh Li battery pack from LG is size of bar fridge. So, off grid, with ROI of about 25%. Yes, this means 4 years to get your money back…Now, battery pack is $5500, but giant Tesla factory in USA and others,means this will drop to say $500 in ten years ( as did plasma TVs). So, if you’re a coal fired generator owner, yes you would dissemble, conflate, confuse and delay for all you’re worth as your business model is dead.” Could this pic show anything more inefficient! Main story points out “By 2030, over two-thirds of our coal fleet will be over 40 years old and 40 per cent over 50 years old. They’ll face high maintenance and operating costs and become increasingly unreliable.” Time to think, then talk. Wind and solar are already cheaper than open cycle gas turbine, without CCS!
