STORY: One of Brazil’s last coal plants roared back to life this year in the southern mining town of Candiota.A powerful business group invested millions to keep its turbines turning at the Ambar plant.Its billionaire owners are betting Brazil would not soon stop burning coal, a major driver of global warming.Cheap renewable energy sources produce over 80% of electricity in the South American country.As host of the United Nations climate summit COP30 this month, Brazil is urging nations to transition away from fossil fuels.President Luiz Inacio Lula da Silva lamented at an event this week that the war in Ukraine had led to the reopening of coal mines.Yet coal plants still produce 3% of Brazil’s electricity.It illustrates how pressure from interest groups and lack of a transition plan can keep coal burning, even in a renewable energy powerhouse.The Candiota plant’s government contract expired last year, leading local businesses to shut down and many residents to leave town.The plant now sells energy on the spot market, helping to meet demand when solar and wind generation fades.Last month, Brazil’s lawmakers approved a bill granting contracts until 2040 for plants run on domestic coal, such as Candiota.But Lula could still veto it.Ambar’s work to keep coal alive puts Brazil in the company of countries such as India and South Africa.Powerful interest groups have undermined efforts to wean the energy system off coal, which is key to local economies.Shutting the coal plant means 10,000 jobs could be lost at Ambar’s operation and the local mine feeding it.Residents are on edge about their livelihoods.Social worker Graca dos Santos was fired from the plant after it lost government contracts.“You cannot suddenly close a plant and change the lives of so many people in a city overnight. What we need now is more time.”Lula’s government has no transition plan for Candiota and has not made much progress on plans for other coal plants.
