If the fertiliser production has a point in manufacture when the fluid is amenable to transport, then for sure, that would make sense.

And you are right, if the same amount of capital and energy was invested in Solar/Wind as in Oil, we'd be in a totally different world. It's cents to dollars, considering the size of the tail AND the current investment.

Here in Australia the problem is the royalty stream to the states. Oil and Gas windfalls when the price of equivalent supply (brent crude I believe for oil, not sure what LNG world price defines the limit) hits $100 is just amazing. The revenue stream to the states is enormous. Their motivation to transfer money into alternatives, instead of sucking on the teat, is zero. States without significant oil revenue seem to do more (SA) -States isolated from the national grid seem to do more (WA) but a site with both high insolation, and good wind, but also massive oil, gas and coal fields (Qld) does as little as possible. It's political reductionism. The crony economy is huge, Mining funds the government and the government reflects mining sector interests over all others.
