Brazil’s New Oil Frontier Could Keep Its Boom Alive For Decades

Brazilian President Luiz Inácio Lula da Silva has hailed a new offshore oil discovery by Petrobras (NYSE: PBR) near the mouth of the Amazon River as a "passport to the country's future", continuing his support for controversial oil and gas drilling in Amazon's ecologically sensitive regions.

Challenges to accelerated adoption still remain, including the need for billions of U.S. dollars in investments in critical battery minerals…

Washington Eases Gasoline Rules as Iran Pressure Campaign Jolts Fuel Costs

Washington is tightening the screws on Iran and loosening the rules on gasoline at the same time as Americans are paying more than $4 a gallon. The Environmental Protection Agency on Thursday authorized an early switch to cheaper winter-grade gasoline, allowing sales of gasoline blended with 10% ethanol beginning September 1 rather than waiting for the normal mid-September seasonal transition. The administration says ending summer-blend requirements early could add hundreds of thousands of barrels per day to domestic gasoline supply and provide…

How Solar Panel Prices Fell 90 Percent In 15 Years

Solar power is far and away the world’s fastest-growing form of energy production, beating out every other form of energy on Earth in 2025. Despite a recent political pivot away from renewable energies in the world’s largest economy, solar power additions continue to shatter its own records year over year as the sector has long since outgrown any need for subsidies. Solar power has simply become too cheap to fail. “We have a plentiful and cheap source of electricity that can be built quickly, almost anywhere in the world,”…
