U.S. producer prices climbed last month at the fastest pace since November 2022, fueled by surging energy prices. The Labor Department reported Thursday that its producer price index — which captures inflation before it reaches consumers — jumped 6.5% from May 2025. It also rose 1.1% from April, same as it did the previous month. Inflationary pressures, intensified by the energy shock caused by the Iran war, are frustrating Americans five months before midterm elections that will determine whether President Donald Trump's Republicans keep full control of Congress.

Even as President Donald Trump boosts coal over clean energy, solar power is hitting new milestones in the U.S. and remains the leading source of new power. New reports released Wednesday by global energy think tank Ember and the Solar Energy Industries Association show the continued growth of solar and decline of coal in the United States despite federal policy. Ember says in May, for the first time, solar supplied more of the nation's electricity than coal, or 12.8%. Coal supplied 12.2%, its fourth-lowest monthly share ever. The Republican president has been helping the struggling U.S. coal industry while curtailing solar and wind. A Democratic California congressman says the coal industry is dying.

The Energy Department says a small nuclear reactor under development at a national lab has reached a crucial milestone that could allow it to produce electricity in the next few years. The microreactor being developed by Antares Nuclear Inc. at the Idaho National Lab reached "criticality" on Thursday, Energy Secretary Chris Wright said. The milestone occurs when a nuclear reactor achieves a self-sustaining chain reaction capable of producing a steady release of energy. Antares is the first private company to bring an advanced reactor to criticality under a pilot program begun last year by the Trump administration.
