Overview of Emission-Free Energy Sources in the U.S. and Nuclear Power's Future

This document analyzes the life-cycle emissions associated with various sources of emission-free electricity generation in the United States. Geothermal contributes 1.3%, photovoltaics less than 1%, hydroelectric power accounts for 29.1%, wind energy provides 34%, while nuclear power stands out with a remarkable 69.2%. Additionally, the document examines nuclear electricity production trends and cost efficiency from 1998 to 2001, highlighting improved capacity factors and lowest electricity production costs. It aims to provide insights into the role of nuclear energy in the 21st century.
