Yes there is plenty of intermittent energy, and while the energy - like any energy - is free, since provided by nature the cost of extracting it into something usable is not free. It has a cost, and that cost has to be weighed up against alternatives such as gas and nuclear. The only truly free energy is overunity energy such as that purported to come from LENR. Whether or not solar, wind, tidal, or wave energy can supply 100% of the energy needs is dependent on where you are on the planet. In northern latitudes 100% solar and wind is not possible - even with storage. And this is without considering the possibility that human advancement may well become ever more energy intensive as we move forward technologically, and poorer countries catch up.
I think EV’s are an interesting, and potentially transformational, technological development of transportation, and I also think that batteries will play a part in grid stabilisation as ‘renewables’ introduce more destabilisation, but let’s not kid ourselves about 100% renewables. It’s just not going to happen - at least with existing technology.
This doesn’t detract at all from the investment case here as there is a tsunami of demand coming for battery grade lithium. But let’s just keep things in perspective about the potential of ‘renewables’ to give us a carbon free energy grid.
