Uranium is best known for the destructive power of the atom bombs, which ushered in the nuclear era at the end of World War II, but given the effectiveness of nuclear power, plants like those at Three Mile Island in Pennsylvania were constructed to generate energy for Americans during the second half of the 20th century. While nuclear power plants were previously not an option and thus opened the door to new, more efficient, and more affordable forms of energy for domestic consumption, the use of nuclear energy understandably unnerved people.
