Ward Whicker, Emeritus Professor of Radioecology - Global energy demands are at an unprecedented high and still growing. Global demand for electricity is projected to grow over 70 percent by 2035. Finding energy sources to power the world's growing population and economy and meet that demand cleanly and responsibly is part of an on-going debate. In spite of many advantages, some people have concerns about nuclear power generation. These fears trace largely to misguided assumptions concerning the actual environmental and health consequences from accidents at Three Mile Island, Chernobyl and, most recently, Fukushima.
