The NewClimate Institute has identified semiconductor supply chains as the technology sector's renewable electricity blind spot. The finding matters because chip fabrication consumes enormous quantities of electricity, yet corporate clean-power targets rarely reach the suppliers that perform it.

The report frames a structural gap. Tech companies purchase renewable electricity for their own operations, and they report those figures prominently. What happens upstream, at the fabs that manufacture their processors and memory, remains largely outside the accounting.

What does the blind spot consist of?

Semiconductor fabrication is electricity-intensive. A fab runs its lithography, etching and deposition tools continuously, and those tools draw power around the clock. Fabrication (the process of printing and etching circuit patterns onto silicon wafers) can consume as much electricity as a small city at a single large site.

That demand sits in tier-two and tier-three positions of the supply chain. Most tech companies contract device assemblers, who in turn contract chipmakers. Renewable electricity claims usually cover direct operations and, at best, first-tier suppliers.

The result is a gap between claim and reality. A company can report 100 percent renewable electricity while its processors come from fabs running on fossil-heavy grids.

Why do current targets miss it?

Renewable electricity targets grew out of direct operational control. Data centers, offices and retail operations are easy to meter, contract and verify. Supplier electricity is not.

The NewClimate Institute's argument is that this boundary has become indefensible. Chips are the physical core of every tech product. Excluding the electricity that makes them from clean-power accounting understates the sector's true footprint.

The institute does not claim the gap is unfixable. It argues the sector has not yet tried to close it in a systematic way, and that semiconductor supply chains deserve the same scrutiny that data centers already receive.

What would closing the gap require?

Three mechanisms dominate the available toolkit:

• Supplier procurement requirements: contracts that require fabs to source renewable electricity, verified through disclosure.
• On-site and near-site generation: solar and wind capacity built at or near fabrication clusters.
• Transparent reporting: supplier-level electricity data published alongside corporate claims, not aggregated into opaque averages.

Each mechanism exists in other industries. Apparel and automotive buyers have used supplier energy requirements for years. The technology sector has not applied them at scale to semiconductors.

What remains unsaid?

The report's framing carries a caveat worth stating plainly. Semiconductor supply chains are concentrated in a small number of countries, and several of those countries run grids where renewable electricity is scarce or expensive. Requiring fabs to procure clean power there shifts cost, and someone will have to absorb it.

The institute does not specify who pays. It also does not quantify how much electricity the sector's chip demand represents in total. Without that number, the size of the blind spot remains an estimate, not a measurement.

Why does this matter now?

Semiconductor demand is rising. Artificial intelligence workloads, electric vehicles and cloud expansion all multiply chip consumption, and every additional fab raises the electricity bill behind each tech product.

That trend turns a reporting gap into a growing physical one. Clean-power claims that ignore fabrication will cover a shrinking share of the sector's real electricity use as chip demand grows.

The NewClimate Institute's message is procedural, not promotional. Measure the supplier electricity. Extend the targets to it. Publish the numbers. The sector's credibility on renewable electricity, the institute implies, depends on whether its claims survive contact with the supply chain that builds its products.

Until then, every clean-power headline from the tech sector deserves one follow-up question: who made the chips, and what powered the fab that made them?
