At GCSE, students are taught the basics of a broad range of physical concepts including energy, waves, Newtonian mechanics, electricity, thermal physics and nuclear physics among others. There is also a practical element (known as "required practicals"), which is conducted in the classroom and then assessed via questions in the final exam papers.
Nuclear energy – energy in the nucleus or core of atoms [1] Nuclear fusion; Nuclear reactor; Nuclear reprocessing; Oil drilling; Oil platform; Oil refinery; Oil shale; Oil well; Osmotic power – or salinity gradient power – is the energy available from the difference in the salt concentration between seawater and river water. OTEC ...
Energy crisis, the need to conserve energy resources; Energy development, development of energy resources — ongoing effort to provide abundant and accessible energy, through knowledge, skills and construction; Embodied energy, the sum total of energy expended to deliver a good or service as it travels through the economy; Energy conservation ...
Renewable energy (also called green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries.
The energy industry provides the energy required for human civilization to function, which it obtains from energy resources such as fossil fuels, nuclear fuel, and renewable energy. Forms In a typical lightning strike, 500 megajoules of electric potential energy is converted into the same amount of energy in other forms, mostly light energy ...
Resources and technology do not constrain the capacity of nuclear power to contribute to meeting the energy demand for the 21st century. However, political and environmental concerns about nuclear safety and radioactive waste started to limit the growth of this energy supply at the end of last century, particularly due to a number of nuclear ...
