How WattCostLab handles innovation news

Primary source first

Research papers, national laboratories, government research programs and institutional technical releases are preferred over reposted summaries.

Readiness is explicit

Research, pilot, field demonstration and commercial availability are not treated as the same thing.

Numbers stay in context

A prototype efficiency, temperature difference or peak-load reduction is tied to its cited test conditions rather than presented as a universal household result.

News connects to decisions

Where relevant, each story links to WattCostLab tools for current products, costs, local energy context and project planning.
