F |

FuelsMaterials capable of liberating energy by nuclear and chemical reactions, including combustion. They commonly have a high energy density. | |
G |
|---|
Grammer termsMethod acting | |
H |
|---|
HydrocarbonsOrganic compounds, such as methane, that contain only hydrogen and carbon. | |
HydropowerConversion of the potential energy of water in rivers or reservoirs to electricity, by using the kinetic energy that is released when it flows to turn turbines. Because rainfall stems from water vapour evaporated from the ocean surface, hydropower is an indirect form of solar energy. | |
J |
|---|
Joule (J) | |
K |
|---|
Kinetic energy | |
M |

Marine carbon cycleThat part of the carbon cycle that involves the circulation of carbon in seawater through biological activity and inorganic processes. | |
MethaneCH4; a gaseous hydrocarbon that is the main component of natural gas. | |
N |
|---|
NewtonThe force that gives a mass of one kilogram (kg) an acceleration of one metre per second per second (m s−2), and is therefore equivalent to 1 kg m s−2. | |
Non-renewable energyEnergy resources that are replenished naturally over extended timescales of thousands or millions of years. As they are exploited faster than they are replenished they are considered as non-renewable. | |
