Barrage
a dam bult across an estuary to generate tidal power
19 of 45

20 of 45
Parabolic reflector
a mirror system that reflects incoming light onto a single point
21 of 45
Potential gravitational energy
the energy of raised position

Coppiced woodland
woodland where the trees are cut to the ground level every 3 to 15 years. The regrowing branches can be used as a biofuel
23 of 45
Fuel cell
an electrochemical device that produces electricity from the chemical reaction between two substances, usually hydrogen or an alcohol, and oxygen
24 of 45
Peak shaving
the process of storing surplus energy to satisfy later demand peaks
25 of 45
Half-life

Affluence
the amount of money that people have to spend
27 of 45
Reservoir
the total amount of a substance present on Earth
28 of 45
Reserve
the proportion of a resource that can be economically exploited with existing technology

Hydrocarbon
a compound of hydrogen and carbon e.g. oil
30 of 45
Carbon
chemical element, a non metal which has two main forms; graphite and diamond. Occurs in charcoal

36 of 45
NOx
oxides of nitrogen
37 of 45
Gassification of coal
burning coal underground for heating or producing energy
38 of 45
Secondary crude oil recovery
pumping CO2 into the oil crater so it comes out and can be used
39 of 45
Tertiary crude oil recovery
pumping chemical detergents so the oil is less viscous and can be pumped out
40 of 45

radiation with enough energy so that during an interaction with an atom, the atom becomes charged or ionized
44 of 45
Virtification
used to store high level radioactive waste
