A nuclear fusion reactor in which hydrogen plasma is held in a torus: a ring-shaped tube.

• Thorium reactor

• Toroidal reactor

• Plutonium reactors

• Uranium reactors

The process of storing surplus energy to satisfy later peaks in demand.

• Peak shaving

• Persistence

• Phytoremediation

Nuclear power that involves the splitting of the nuclei of large atoms such as uranium 235 and plutonium 239.

• Nuclear Forming

• Nuclear fishing

• Nuclear fusion

• Nuclear Function

The extraction of crude oil where pressure is maintained by pumping water or natural gas into the oil reservoir.

• Primary oil recovery

• Secondary oil recovery

• Tertiary oil recovery

The extraction of crude oil where the viscosity of the oil is reduced using methods such as the injection of steam, solvents or bacteria.

• Primary oil recovery

• Secondary oil recovery

• Tertiary oil recovery

The extraction of crude oil where the oil is forced to the surface by the pressure of water beneath the oil or natural gas above or dissolved in the oil.

• Primary oil recovery

• Secondary oil recovery

• Tertiary oil recovery

A method of generating electricity using the downhill flow of water to turn turbines and generators.

• HEP

• Photovoltaic

• Kinetic energy recovery system (KERS)

• Concentrating solar power (CSP)

An approach to control of pollution, especially ionising radiation, where levels are kept as low as is practically achievable, taking into account economic and technological factors.

• ALARA

• DEFRA

• CEFAS

• IUCN

A power station that has a high overall energy efficiency because the heat energy from the condenser cooling water is harnessed and used, often for heating buildings.

• Concentrating solar power (CSP)

• Cooling towers

• Combined heat and power station (CHP)

• Kinetic energy recovery system (KERS)
