Ant,

Worldwide experience shows that government owned businesses provide poorer services at higher costs.

No Ant, I did not prove you right.
It is simple enough, if base load stations provide base load they make
money. However if you introduce a rule that says they cannot supply
if solar or wind is available they cannot be economic whether run by
government or business.
Surely that is not hard to understand ?
If you still do not understand that then I suggest you try another web site.
Or perhaps go into politics.
