U.S. energy inflation pressures Trump

Highlights

U.S. petrol prices jumped 9.1 per cent in September, adding pressure on Trump's campaign pledge to halve energy costs within 12 months.
Centre for Economic Policy Research estimates that ten new data centres in a utility area can propel household electricity bills up by 13 per cent, intensifying voter backlash in key swing states.
Iran war has driven average U.S. petrol prices up 45 per cent since its onset, highlighting limits of White House leverage and bolstering global oil and power inflation.

Polling and price trends reshape the energy debate

As reported by Financial Times, recent U.S. consumer price index data shows petrol prices rose 9.1 per cent in September, the sharpest increase since the war in Iran began, adding pressure to a White House that had promised to cut energy costs quickly after taking office.

Trump made cheaper energy a central campaign pledge in 2024, saying at an Economic Club of New York event in September that year that prices could be cut by half or more within 12 months. The Republican message linked lower inflation to expanded domestic energy production, but the current rise in petrol prices is weakening that argument as voters prepare to cast ballots in just over two weeks.

An October Reuters/Ipsos poll found 60 per cent of Americans disapprove of Trump’s handling of Iran, while 78 per cent blame the White House for higher prices. Findings cited from the Searchlight Institute also suggest voters see other remedies as more important than drilling, including curbing excessive utility profits, ending the Iran war, improving grid efficiency and restricting data centres.

AI power demand and war add to Republican risks

The pressure is extending beyond petrol into household electricity bills, where data centre growth is becoming a political liability. An August discussion paper from the Centre for Economic Policy Research estimated that adding 10 data centres in a utility territory raises household electricity prices by 13 per cent, while a single large facility can push prices up by 4 per cent.

That issue is especially sensitive in swing states. In Pennsylvania, electricity rates rose 18.9 per cent last year, and polling cited in the article indicates many voters directly associate rising prices with data centre construction. In Ohio, Senator Jon Husted faces political fallout after backing efforts to attract data centres, while rival Sherrod Brown is arguing that companies, not consumers, should absorb AI-related power and infrastructure costs.

The broader inflation problem also feeds criticism that Republican energy policy is serving powerful business interests rather than households. The article argues that higher oil prices help domestic shale economics, while another Reuters/Ipsos poll in August found that even half of Republicans believe Trump’s business decisions affect his policy choices.

The Iran war remains the largest political and economic drag on the administration’s energy agenda. The conflict has lifted average U.S. petrol prices by 45 per cent since it began, while also highlighting Washington’s limited leverage over Iranian oil flows and China’s position as both a major buyer of Iranian crude and a likely beneficiary of a faster global shift to electric vehicles and cleaner energy, according to the IEA.

In our earlier article on the U.S. AI data center boom, we explained that many planned projects are being delayed or scaled back as financing costs rise and construction budgets overrun. We also noted that grid constraints and growing local opposition are forcing developers to secure power more aggressively, raising doubts about how quickly new computing capacity can realistically come online.
