Tom, you can get an EV for around 27k. not exactly unobtanium...
....A problem was cited.In South Australia in 2019, some days approximately 75% of the total load of the state was being supplied by solar PV on houses and windenergy.This is approaching a dangerous situation, where the controller only has control of 25% of energy to try and regulate to 100% of the load. ....
Over a large area in somewhere like Australia PV may well be able to satisfy a significant part of the base load.
Does the sun shine at night in Australia? I've never been so I don't know.
They have huuuuuge batteries.
Have you read the report? The report puts the size of the batteries into context with the electricity demands. The batteries might be huge in terms of typical battery size, but they are puny compared to the demand from the electricity grid.
Lets get real here. With renewable energy the energy source is free. That makes it a formidable competitor to all types of conventional energy generation and of course those invested in that will fight back.
I don't see any need for a fight.What's needed is to recognize the different roles and to pay the different types of suppliers for the role that they provide. For example one would probably only pay renewables such as solar and wind for the energy they produce. But there will always be a need for conventional power stations to fill gaps and they should be paid principally for capacity - and maybe an energy payment that simply covers their fuel costs. That way they have an incentive to be available but won't care whether or not they are used....R
Ardly,I do know about the electricity generation industry; my brother has jsut retired from 40 years working in it. Your description is a distortion of the truth and mixes base load with the daily variation in load and fails to take into account the variable nature of renewable generation.
