Corrections
When we get something wrong, we fix it in place and record it here — with what it used to say, so you can judge the change yourself.
We correct typos and broken links silently. Anything that changes a figure, a safety statement, a date, an incentive detail or a claim about ourselves gets an entry below, and the affected article's "facts checked" date moves.
Found something wrong? Tell us. Corrections of substance are credited to the reader who reported them, unless they ask otherwise.

What It Actually Costs to Charge an EV at Home in 2026
WasThe FAQ said a typical EV costs "about 4 to 5 cents per mile", while the table and chart on the same page showed 6.0 ¢/mile for a typical sedan at 3.5 mi/kWh.
NowThe FAQ now gives about 6 cents per mile for a sedan at 3.5 mi/kWh, and 5 to 7 cents across most cars — matching the table, the chart and the conclusion.
Two different answers to the headline question of the article, on the same page. The 6.0 ¢ figure was the correct one.
Six articles citing the US average electricity price
WasThe 18.44 ¢/kWh US residential average was described as an "August 2026" figure.
NowIt is described as EIA data for May 2026, released 23 July 2026, with a note that the EIA reports retail prices about two months in arrears.
The number was right but the date was not. The EIA had not measured August 2026 when we published, and presenting a May measurement as a current-month reading overstates how fresh it is.
What It Actually Costs to Charge an EV at Home in 2026
WasThe FAQ gave 320 kWh metered per 1,000 miles and about $59 a month.
Now325 kWh and about $60 a month, matching the body of the article.
Rounding drift between the FAQ and the section it summarises.
Site-wide funding disclosure
Was"HomeEnergyX is reader-supported and funded by display advertising."
Now"HomeEnergyX may be supported by display advertising. Advertising does not influence our calculations or conclusions."
Display advertising is not yet running on the site, so the original wording described a funding arrangement that did not exist.
Site description and the Best Chargers category
WasThe site described itself as offering "hands-on guides", and the Best Chargers category promised chargers "tested and compared".
Now"Research-backed guides", and a category description about which specifications change the outcome.
We do not bench-test chargers — the About page said so already, which made the other two claims a contradiction rather than a stretch.
What Size Wire Does an EV Charger Need?
WasEvery voltage-drop percentage on the page was roughly 1.35× too high — 8 AWG copper carrying 40 A over 100 feet was given as 3.5% — and the article concluded that the 3% guideline fails beyond about 75 feet.
NowThe same run is 2.6%, the table reads 0.7 / 1.3 / 2.0 / 2.6 / 3.9%, and 8 AWG holds the 3% guideline to about 115 feet. The hero chart bands were redrawn to match.
The error was found by writing the circuit calculator, which computes Vd = 2·K·I·L ÷ cmil from the same inputs and disagreed with the published table. Hand-checked: 2 × 12.9 × 40 × 100 ÷ 16,510 = 6.25 V on 240 V, which is 2.6%. Overstated drop pushes readers towards heavier, more expensive conductor than the run needs.
