Trump goes "all-in" on Grand Canyon energy breakthrough (Ad)

A drilling crew near the Grand Canyon uncovered a clean energy well producing nearly eight times the output of Saudi Arabia's largest oil field, with potential to last two million years. While the One Big Beautiful Bill Act eliminated federal credits for solar, wind, and EVs, this energy source was reclassified alongside oil and nuclear power and given eight years of tax credits. Google signed a 15-year contract, and Bill Gates committed $100 million. One company controls the entire supply chain behind this discovery.tc pixel
