Electrical power, like all commodities the price/value is determined by the supply/demand equation.
As we close down our remaining base load thermal powered stations and rely on renewables we will become hostage to the energy providers.
When the sun isn't shining and the days/nights are calm, god know what the price will be, supplied by those fortunate to have spare generating capacity.
Observe the price fluctuations at present for the most expensive power in Australia, being South Australia at present.
We really are heading for disaster.
