New modeling uses the latest renewable energy and battery cost data to demonstrate the technical and economic feasibility of achieving 80 percent clean (carbon-free) electricity in the United States by 2030. The report finds achieving an 80 percent clean electricity grid by 2030 is technologically feasible, would not raise customer costs or compromise reliability, and would deliver major benefits including $1.5 trillion in clean energy capital investments and $100 billion in transmission capital investments, while avoiding over $1.7 trillion in health and environmental costs, including 93,000 avoided premature deaths. Modeling data is available here.
