Energy is nominally 8% of CPI, but energy costs are embedded in costs of production, transportation, etc. about 20% of the movements in CPI are attributed to energy costs.
Not enough to say “it makes no sense inflation adjusting the price of energy, when inflation is caused by energy”, but not enough to ignore it either.
President Biden is free to ignore economic principles, but economic principles will not ignore him—or Americans, who are taking the hit from these failed policies every day.
I do not trust the numbers for several reasons. The first is that the CPI data algorithm has been massaged over the years to suit the purpose of the. government.
The second is that the Biden years numbers have not had a chance to reflect the administration’s disastrous energy policies.
Another factor not reflected in the graph is the truly revolutionary nature of the technology improvements in oil extraction developed and implemented during the Trump administration. The Democrats in general both nationwide by essentially banning oil exploration on public land and in the states like New York banning fracking for natural gas and California clamping down on offshore oil extraction have tried to reverse many of those gains.
The Golden State is rushing to the aid of its people.
So how about all the California illegals? I dunno.
Sure, fight higher prices by giving people more money to spend. Which will only push prices even higher.
At least in this case it’s more like a tax refund (or a refundable tax credit).
Or are you saying that the government should raise taxes to fight inflation? 
More taxes and less spending, yes, are the traditional ways. Lower demand side for reducing prices.
As long as the government uses the extra to pay down debt, rather than to fund more spending, yes. You lower inflation by reducing demand. Less money in consumer’s pockets yields less demand.
Inflation only perpetuates itself when the ‘solution’ is handouts to help people afford the higher prices.
speaking of doing it wrong, here’s CA paying $17B to fight inflation
Fed watch
and also
In other government shenanigans, “the dog ate my oil report”
The debt was created to fund more spending and cash is fungible – the govt will pay down the debt with one hand, then increase it with another. Good luck getting any conservative politician to advocate for raising taxes regardless of stated purpose.
From the Wall Street Journal
In February 2021, Larry Summers was right. The former Treasury secretary warned that President Biden’s stimulus package was far too large and would lead to far too high inflation.
Former Treasury Secretary Larry Summers, a Democrat, offers his opinion
This guys bullish on inflation and seems to have pretty good reasons

When home prices soar, you have home prices that are up almost 40% in the last 28 months. That’s an enormous rise. And owners’ equivalent rent in the last 2 1/2 years is up just about 8%. That’s all just under 4% annualized.
So what happens to that difference, that 30 percentage point difference? It shows up over the next decade, with about half of it showing up in the next three years. That means we’re going to see inflation run hot for the next three years by about 5% a year.
Rob Arnott: Ben Bernanke about 10 years ago famously said economic expansions don’t die of old age, they’re murdered by the central bank. And there’s a lot of truth to that. We have inflation. It’s created by a massive stimulus spending, by supply chain disruptions closely related to the disruptions, the war in Ukraine.
And which of these does the Fed have any control over? None.
I’m no economist, but the above makes some assumptions:
Rising mortgage rates put pressure on housing prices. The risk of recession puts pressure on housing prices and rents. So as with almost everything else, take it with a bucket of salt.
The government giveth. The government taketh away. 
Ah, now the oil report comes out and it wasn’t those Evil Oil companies not producing after all. So much for that last Bidenflation excuse.
Meanwhile, on the international begging front,
They would dump more of the Strategic Reserve before midterms if they could, but there are physical limits to how fast they can get the oil out and they’re already maxed out dumping our reserves full throttle.
and which OPEC countries have spare capacity again? Apparently not that many, Saudi saying they don’t have much available.
Oil prices moved up on the delayed EIA report and seem to be heading further that way unless the Fed manages to get us a serious recession instead of just a small one.
Those producers are more than willing to wait patiently, knowing that after things with Russia settle down and oil prices begin to naturally drop, the US will start propping up the price by beginning to refill our reserves.
I’m no economist, but isn’t giving people money to account for higher prices just like throwing gasoline on a fire?
Possibly. But in this case it’s a state income tax refund. Being called “inflation assistance” or “stimulus” or “gasoline for the fire” doesn’t change the truth of what it is. No money is being created.
But giving out money from the state government, even if it’s not printing money the way the Feds do, is still pulling forward future demand to today when it will increase inflation. If they are borrowing more to fund this extra refund, they’re taking investment capital from rich municipal bond investors and giving it to people who will blow it right away.
