Vinod Ramireddy: There is a relatively new technology for generating electricity. It is combined cycle gas turbine and steam turbine using natural gas. If the world would use all energy sources for their highest and most important purposes, we would not be using natural gas to generate electricity. We would be using natural gas for things it does best and that other energy sources can't do as well. But that is not the way the world is working. We use whatever is cheapest for now and don't save precious resources for important uses in the future. That means that combined cycle gas turbine and steam turbine are the cheapest form of generating electricity in places where natural gas is plentiful.
Akanksha Gupta: Most of the world's biggest nuclear power plants by net capacity are in East Asia. Regular inspection and safety measures have been stepped up at the large capacity nuclear power stations following the Fukushima nuclear disaster in 2011.
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.
Robert Schenter, physicist: He specialized in the production of radioisotopes in reactors for nuclear medicine. Much of nuclear medicine depends on a steady supply of an isotope called molybdenum-99—“Mo-99” for short. A by-product of nuclear fission, Mo-99 decays to produce another radioactive substance, technetium-99m, which is employed in more than 16 million nuclear imaging procedures every year in the United States alone, including sentinel node biopsies in cancer surgery, bone scans, and cardiac stress tests.
Wolfgang Buescher: Extreme Green Activists demand that mankind protection "nature" above everything else. The same people demand the installation of tens of thousands of wind turbines in each country. Wind turbines destroy nature, the environment, and kill birds and bats that they insist everyone protect. Besides this ludicrousness, powering modern electrical grids with such variable electric power is the opposite of what most technical people insist on."
