Energy prices increased despite removal of carbon tax

I thought I would analyse my energy prices since moving into my home nearly four years ago.
When plotted upon a graph they make interesting viewing.
At the end of 2014, electricity was 24.90 c/kWh, dipping to a low of 21.98 when the carbon tax was abolished (with which I vehemently disagree, because I happen to care more about my kids’ future than my own), then rising to a current peak of 28.76 c/kWh, a staggering rise of 30.85% since the abolition of the tax.
During the same period, gas started at 3.287 c/MJ, rose for no apparent reason to 3.908 in August 2014, dropped to 3.287 for the aforesaid selfish cut, and has now climbed to 3.990 c/MJ, a hike of over 21 per cent.
For comparison, my water rates have remained relatively static.
It’s a pity that extracting hydrogen from water via electrolysis is uneconomical.
As we were promised lower energy prices as a result of the removal of the carbon tax, could someone “please explain” to this mathematics graduate just why they have actually risen under this government?
