Why Nuclear, Why Now?

Nuclear energy provides approximately 20% of the electricity in the US and is the largest producer of the emission-free electricity. However, it is often misunderstood and misrepresented. This talk will highlight some of the pros and cons of nuclear energy and underlines why an expansion in nuclear energy is required not just for the U.S., but also around the world.”
