Generation of electricity from nuclear energy has also grown steadily in the United States, despite the old age of many nuclear power plants. In August 2017, the first nuclear reactor new in several decades began operation. Located in Tennessee, the Watts Bar has not arrived without controversy as the U.S. continues to retire other reactors and other utility companies abandon unfinished nuclear projects.
Renewable energy has also gained momentum in the past decade. President Obama first called for sizeable increases in renewable energy generation in 2009. Since that time, renewable energy production has seen steady increases, especially in wind production. However, hydroelectric still leads renewables in terms of overall energy production, followed by wind and solar. The outlook for renewable energy in the U.S. is uncertain for the immediate future with President Trump retracting the U.S.'s commitment to the Paris Climate Agreement in 2017.
