In yet another sign that the global economy can survive without breaking the Earth, a gigantic steel mill in Pueblo, Colorado is getting a renewable energy makeover with a spanking new 300-megawatt solar power plant. The developer, Lightsource bp, cites the “competitive price of solar energy” as a factor that will keep the mill humming for years to come and save jobs for 1,000 local workers, to boot. As for coal jobs, not so much. The new PV plant will help smooth the way to retiring Colorado’s largest remaining coal power plant.
