Solar is cheaper. Coal costs much more than 2.42c per kWh.
Who's the moron now?
"A consortium of the Chinese solar panel maker and project builder JinkoSolar JKS 4.60% and the Japanese developer Marubeni put in a bid to build a large solar panel farm near the sun-rich city for a jaw-dropping 2.42 cents per kilowatt hour.
That’s by far the lowest solar panel farm bid out there. A few ultra low-cost large solar panel farms have recently achieved around 4 cents per kilowatt hour, and earlier this year the previous record bid for a solar panel farm in Chile was 2.91 cents per kilowatt hour."
Current domestic PV panels are in the region of about 18% efficiency. So they convert 1kW of solar energy into 180W of electricity. If CSIRO have panels hundreds of times better where is the energy coming from? They would be almost 100% efficient just 5 times better, if that's what you mean?
Wind energy unlikely to ever be economical you say!
Try 2.5c per kWh.
