A Contract Test for Macaíba's Wind
Brazil's new data-centre tax law, Redata, asks companies to cover their electricity demand with renewable contracts — measured annually, not hourly. In a Northeast grid that curtailed 20 per cent of its wind and solar potential in 2026, that test proves ownership of clean megawatt-hours, not absorption of stranded ones. The forthcoming decree can require hourly metering data without narrowing the statute's scope.

The Cleanest Air in India Costs the Most Electricity
India's largest generic pharmaceutical manufacturers now procure seventy to 85% of their electricity from renewables, a figure that flatters the underlying problem. Pharmaceutical cleanrooms account for fifty to 80% of a sterile plant's total energy and run continuously at setpoints regulators inspect without warning; changing the grid mix does not move the meter. Model predictive control of chilled-water loops is where a ten-to-20% reduction is now measurable.
