Guess who's building nuclear power plants. The Shah of Iran is sitting on top of one of the largest reservoirs of oil in the world. Yet he's building two nuclear plants and planning two more to provide electricity for his country. He knows the oil is running out and time with it. But he wouldn't build the plants now id he doubted their safety. He'd wait. As many Americans want to. The Shah knows that nuclear energy is not only economical, it has enjoyed a remarkable 30-year safety record. A record that was good enough for citizen of Plymouth, Massachusetts, too. They’ve approved their second nuclear plant by a vote of almost 4 to 1. Which shows you don't have to go as far as Iran for an endorsement of nuclear power. Nuclear Energy. Today's Answer.
