President Donald Trump used a Cabinet meeting on Tuesday to declare that “fossil fuel and nuclear energy is what works” and that his administration will not approve new wind-power installations, saying bluntly, “We don’t allow windmills.” The remarks underscore a policy shift that has already produced executive actions aimed at reversing the previous administration’s support for renewable energy. Health and Human Services Secretary Robert F. Kennedy Jr. told the meeting that an inter-agency team—comprising the Interior, Commerce, Energy and Defense departments—is reviewing offshore wind projects approved under former President Joe Biden. The coordinated review marks the strongest federal push yet to curtail an industry that had been central to U.S. decarbonisation plans. Last week the Interior Department ordered Danish developer Ørsted to stop work on the $6.2 billion, 65-turbine Revolution Wind farm off Rhode Island, a project that was 80 % complete and expected to power more than 350,000 homes in New England. Separately, the Justice Department signalled it will seek to rescind permits for the planned 114-turbine US Wind project off Maryland’s coast. Union officials say the Rhode Island halt threatens more than 1,200 construction jobs and has rattled investors across a sector that already supplies over 10 % of U.S. electricity. Trump argued that expanded coal and next-generation nuclear reactors are needed to meet surging electricity demand from artificial-intelligence data centres, saying the country must at least double current generation capacity. State officials in Connecticut and Rhode Island warn that prolonged federal delays could raise blackout risks and saddle consumers with higher costs, while industry groups caution that the administration’s actions are chilling billions of dollars in planned clean-energy investment.
