Longtime Slashdot reader AmiMoJo shares a report from the Financial Times: Solar power developers want to cover an area larger than Washington, DC, with silicon panels and batteries, converting sunlight into electricity that will power air conditioners in sweltering Las Vegas along with millions of other homes and businesses. But earlier this month, bureaucrats in charge of federal lands scrapped collective approval for the Esmeralda 7 projects, in what campaigners fear is part of an attack on renewable energy under President Donald Trump. "We will not approve wind or farmer destroying [sic] Solar," he posted on his Truth Social platform in August. Developers will need to reapply individually, slowing progress. Thousands of miles away on the other side of the Pacific Ocean, it is a different story. China has laid solar panels across an area the size of Chicago high up on the Tibetan Plateau, where the thin air helps more sunlight get through. The Talatan Solar Park is part of China's push to double its solar and wind generation capacity over the coming decade. "Green and low-carbon transition is the trend of our time," President Xi Jinping told delegates at a UN summit in New York last month. China's vast production of solar panels and batteries has also pushed down the prices of renewables hardware for everyone else, meaning it has "become very difficult to make any other choice in some places," according to Heymi Bahar, senior analyst at the International Energy Agency. [...] More broadly, the US's focus on fossil fuels and pullback of support for clean energy further cedes influence over the future global energy system to China. The US is trying to tie its trading partners into fossil fuels, pressing the EU to buy $750 billion of American oil, natural gas, and nuclear technologies during his presidency as part of a trade deal, scuppering an initiative to begin decarbonizing world shipping and pressuring others to reduce their reliance on Chinese technology. But the collapsing cost of solar panels in particular has spoken for itself in many parts of the world. Experts caution that the US's attacks on renewables could cause lasting damage to its competitiveness against China, even if an administration more favorable to renewables were to follow Trump's.

According to the Wall Street Journal, SpaceX is reportedly poised to secure a $2 billion Pentagon contract to develop hundreds of missile-tracking satellites for President Trump's ambitious Golden Dome defense system. The Independent reports: The planned "air moving target indicator" system in question could ultimately feature as many as 600 satellites once it is fully operational, The Wall Street Journal reports. Musk's company has also been linked to two more satellite ventures, which are concerned with relaying sensitive communications and tracing vehicles, respectively. Golden Dome, inspired by Israel's "Iron Dome," was announced by Trump and Secretary of War Pete Hegseth at the White House in May and will amount to a complex system of satellites and weaponry capable of destroying incoming missiles before they hit American targets. The president promised it would be "fully operational" before he leaves office in January 2029, capable of intercepting rockets, "even if they are launched from space," with an overall price tag of $175 billion.
