A Solar Farm Becomes a Data Centre, Wisconsin Campaigns Against Solar, and LONGi Breaks the Tandem Efficiency Record

The Trump administration's energy priorities are made concrete: a Bureau of Land Management solar project repurposed for AI compute. Meanwhile, China sets higher renewable targets, LONGi posts a world-record cell efficiency, and anti-solar campaigning becomes a campaign strategy in Wisconsin.

Trump administration converts approved BLM solar project into an AI data centre site

The Trump administration redirected a Bureau of Land Management-approved solar farm in the western US toward data centre development for AI compute — the most direct illustration yet of the administration's preference for AI infrastructure over clean-energy generation on federal land. The original solar developer was denied an extension of its permit.

Why it mattersA solar permit converted to a data centre permit is not an energy policy shift in the abstract — it is a physical site that will now burn grid power rather than generate it, with a decision that will take years to reverse.

Anti-solar protests are becoming a campaign move in Wisconsin

Opposition to solar farm development has emerged as a political campaign tactic in Wisconsin, with candidates in rural districts running explicitly against proposed solar installations. Heatmap News reports a pattern of organised turnout at planning meetings and social media campaigns linking solar projects to absentee ownership and land-use grievances.

Why it mattersWhen solar opposition becomes a campaign tool rather than a planning objection, the regulatory process changes — permitting timelines lengthen, and the political cost of approvals rises for local officials in swing districts.

LONGi breaks world record again: 35.5% efficiency for silicon-perovskite tandem solar cells

LONGi Green Energy announced a new world record of 35.5% conversion efficiency for crystalline silicon-perovskite tandem solar cells, surpassing its own prior record. The result was independently certified and represents the highest efficiency yet reported for a commercially scalable solar cell architecture.

Why it mattersEach tandem efficiency record narrows the gap between lab silicon-perovskite cells and the theoretical ceiling, accelerating the timeline for commercial deployment of next-generation panels at costs below current premium silicon.

Qnetic opens US flywheel energy storage factory to serve wind and solar grids

Qnetic, a flywheel energy storage company, opened its first US manufacturing facility to produce kinetic grid-storage systems intended to provide short-duration frequency regulation and smoothing for wind and solar power plants. Flywheel systems offer near-unlimited cycle life and faster response times than lithium-ion at the cost of lower energy density.

Why it mattersA flywheel factory opening alongside lithium-ion's scale-up signals that grid operators are seeking complementary storage chemistries rather than a single dominant technology — particularly for the millisecond-to-minute response range where batteries degrade fastest.

China eyes a major increase in its renewable energy consumption mandate

China is moving to raise its mandatory renewable energy consumption target, the policy mechanism that requires industrial and commercial electricity users to source a minimum share of power from renewables. The proposed increase, which would take effect from 2027, is intended to accelerate grid integration of the country's rapidly expanding solar and wind capacity.

Why it mattersA higher consumption mandate is the policy lever that converts surplus renewable generation into contracted demand — addressing China's grid curtailment problem without requiring new grid infrastructure.
