Irene Aegerter, physicist, Simon Aegerter, physicist: Nuclear Energy has a bad name and is allegedly not wanted by the people. Yet, even after Harrisburg, Tschernobyl and Fukushima it remains the cleanest, safest and most environmentally safe source of energy and – if done right – will become the cheapest. With new generations of nuclear reactors, the perceived dangers of nuclear power will be eliminated: The Generation IV reactors are inherently safe in normal and abnormal operations, they are proliferation resistant and they use the long lived "waste" isotopes as fuel. They utilize Thorium and all of the Uranium, thereby making the available resources essentially inexhaustible.
Bill Gates, Microsoft: Many people without reliable access to electricity live in rural villages where even health clinics can’t count on having power. After an outage, doctors sometimes have no way of telling whether the life-saving vaccines in their refrigerators have spoiled. It can be even more stressful if a power outage occurs at night. Sometimes health workers have no choice but to treat patients by candlelight, or by the light of a mobile phone.
Kelvin Kemm is a nuclear physicist, Chairman of the South African Nuclear Energy Corporation and CEO of Nuclear Africa (Pty) Ltd: South Africa is the nuclear power poster child for countries across Africa and around the world. They have everything needed to expand their nuclear power program. They have been working to promote use of nuclear power, nuclear medicine and nuclear science across the Continent of Africa. It is one of the best examples of countries wanting to use this very important energy source.
Praveen Duddu: Hydropower is one of the oldest and most widely-used renewable sources of energy. China, the world's largest producer of hydroelectricity, operates two of the 10 biggest hydroelectric power plants in the world, including the world's largest Three Gorges project.
