A battery system that stores excess energy when it’s plentiful will power an apartment building in Buffalo, New York, when the grid is strained and electricity is costly. The manufacturer and state officials hope it will show that larger batteries can safely operate where people live and work. Buffalo-based battery storage manufacturer Viridi and developer Good Carbon Co. say the lithium-ion battery system is connected to the electric grid for Peace Bridge Place. Viridi says the 3.75 megawatt-hour system can power the building for several days. It's among the largest of these systems in a U.S. residential building.

Ukrainian President Volodymyr Zelenskyy has urged supporters to defend new U.S. sanctions against Russia. It comes after President Donald Trump signed an executive order pausing a package of restrictions targeting the Russian economy. The White House's decision raises fears that Ukraine could be further exposed to Moscow’s assaults as winter approaches. Zelenskyy calls Trump's move unfortunate but refrains from criticizing him. He hopes the sanctions can be revived. On Saturday, Zelenskyy reports that Moscow carried out a massive strike on Ukraine’s energy infrastructure, targeting over 15 sites. Ukraine’s air force says most of the attacks were suppressed or destroyed.

California is bracing for fire weather, with thousands potentially losing power as utilities aim to prevent wildfires during hot and windy conditions. The National Weather Service has issued a Red Flag Warning for parts of Northern and Central California starting Thursday. Pacific Gas and Electric Company has notified 70,000 customers about possible power shutoffs beginning Wednesday night. Southern California will also experience gusty conditions as Santa Ana winds strengthen. Los Angeles officials are preparing for the weather by pre-deploying personnel and equipment. Authorities are urging residents to stay informed and have a plan in place.

Mohammed Saber and his family rely on a solar kit for electricity at the bamboo-and-tarpaulin shack they call home at a camp for Rohingya refugees in Bangladesh. The family fled the violent crackdown in Myanmar in 2017. The portable solar panel was provided as humanitarian aid and Saber says it allows them to charge phones, cook, and study at night. Experts note that solar energy is increasingly used in disaster relief due to falling costs and improved technology. Solar kits are portable and independent of traditional grids, making them invaluable in emergencies. However, funding and bureaucracy remain obstacles to wider adoption in disaster zones.

Hurricane Isaias is forecast to miss the oil industry’s biggest hubs along the Gulf Coast. But industry experts say it could still nudge fuel prices higher if it triggers power outages that shut down refineries for processing crude. An extended shutdown of refineries would put a crimp in fuel supplies that already have taken a hit from the ongoing conflict in the Middle East and Russia’s war against Ukraine. Experts say that could cause fuel prices to rise by a few cents or even as much as a dollar a gallon. Refineries in Pascagoula, Mississippi, and Mobile, Alabama, account for 2.4% of the nation’s refining capacity,

The Supreme Court is considering whether local governments can sue oil and gas companies for climate change costs. On Monday, key justices expressed skepticism about the potential flood of litigation if the case from Boulder, Colorado, proceeds. Chief Justice John Roberts questioned the implications of allowing municipalities nationwide to file similar lawsuits. Boulder officials argue that companies like Suncor and Exxon should be accountable for climate-related disasters. The companies claim the Clean Air Act gives the federal government regulatory power, not states. The Trump administration supports the companies, arguing the lawsuits are unconstitutional. The court's decision could impact similar cases across the country.
