In fact, Evergy has asked permission to extend the life of an old coal-fired power plant to meet growing demand, including from the battery factory. With my students at Wellesley College, I’ve been tracking the boom in investments in clean energy manufacturing and how those projects – including battery, solar panel and wind turbine...
