Biden excelled when he talked about investing and green energy to combat climate change. He focused on the fact that these investments can support new jobs and that both labor groups and environmental organizations support his plan. Trump tried to fearmonger about the threat reducing reliance on fossil fuels poses to American industry, but the fact is that most Americans are concerned about climate change and want politicians to take strong action to counter it. Talking about the transition away from fossil fuels is a positive, enthusiastic way as Biden did makes for a powerful message on this point.
