Nuclear energy generates electricity more efficiently than other energy sources such as coal, according to Nuclear power plants are not heavy polluters in the same manner as coal or oil. More »

Wind energy is sometimes used to grind grain or pump water, but as of 2014, it is mostly used to generate electricity to power homes and businesses. Wind energy works by using turbines to take the kinetic energy of the w... More » Science Environmental Science Conservation

When atoms gain energy, electrons jump to higher orbits and the entire atom moves around more energetically. At set energy levels, the atom changes its physical state of matter from solid to liquid to gas to plasma. More »

Nuclear fission is used to generate electricity, for the destructive component of nuclear weapons and to break down radioactive elements into other elements. In nuclear fission, a radioactive element is broken down into ... More »

Nuclear fission is a clean and efficient way of producing energy but can be dangerous if safety precautions are not taken and followed. It is a controversial source of energy production that powers a large part of the wo... More »

Petroleum, natural gas, coal, nitrogen, uranium and water power are examples of conventional sources of energy. They’re also called non-renewable sources of energy and are mainly fossil fuels, except water power. More »

Nuclear energy provides power, heat and electricity by splitting atoms in a process called nuclear fission. The heat produced by fission creates steam that powers the turbines, thus generating electricity. Nuclear energy... More » Science Physics
