Transitioning the energy sector to zero or net-zero emission of greenhouse gasses (GHG) and substantially reducing other pollutants is a massive, costly, and long-term effort. The typical starting point and centerpiece of energy decarbonization is the electric power sector. The sector is a large direct GHG emitter. It already has many technological, non-carbon emitting alternatives that are rapidly declining in capital and operating costs and improving in performance, making electricity the least expensive and accessible energy carrier to decarbonize.
