Cleaner energy

means Cleaner air.

Plant Vogtle Units 3 and 4

nuclear energy plants release zero greenhouse gases while producing electricity. a single uranium pellet the size of a pencil eraser produces as much electricity as 17,000 cubic feet of natural gas, 1,780 pounds of coal or 149 gallons of oil. nuclear power plants already provide about 20 percent of the power generated in georgia. nuclear energy is clean, safe and proven. Through energy efficiency, conservation, new renewable energy sources, nuclear energy, and new environmental controls, we can continue to make our energy supply cleaner and more secure.
