Nuclear Power in the U.S. Green sources of electric power such as wind and solar are appealing as they emit minimal pollution and carbon while producing power. The wind does not blow constantly, however, nor is the sun out around the clock and electric storage technology has not advanced to the point of capturing energy from any source sufficient to power an entire electrical grid. Other forms of energy that run almost continuously – such as nuclear power1 – are required to fill any gaps in production of electricity from the wind or the sun. What is the state of nuclear electricity generation in the U.S.? Unfortunately, after a strong pace of nuclear power plant construction in the 1970s – 1990s2, the country lost enthusiasm for building new facilities. Construction was expensive, approvals increasingly difficult to obtain and publicity surrounding the relatively few nuclear facility accidents discouraged development.3 The nuclear share of electricity generation in the U.S. rose from 2% in 1971 to around 20% in 1991, where it has remained. In comparison, wind’s share is 9% and solar’s is 3%.4
