Later this week, a huge new solar array on Colorado’s southern High Plains will officially launch — and proponents of a global energy transition will have a new beacon for their cause. The $285m Bighorn Solar array, developed by Lightsource BP just outside Pueblo, the city that made much of the rail track that snakes across America’s west, will be one of the largest solar facilities east of the Rockies. The electricity it generates will help Pueblo make the “cleanest steel and engineered steel products in the world”, according to Evraz, the Russian mining conglomerate that owns the city’s 140-year-old steel works. Bighorn launches just as a global energy crunch sparks debate about how quickly — or not — the world should replace fossil fuels with renewables.
