Renewable Resources
resources that are reformed relatively quickly
3 of 26
Electrolysis
the splitting of molecules using electricity
4 of 26
Non-renewable Resources
resources that are renewed so slowly that the amount available for use is effectively finite
5 of 26
Deplete
to reduce the mount of a resource that is available
6 of 26
Energy Density
the amount of energy in a particular mass of fuel or that can be harnessed by a particular mass of equipment
7 of 26
Intermittent
a process or resource that is not constantly available
8 of 26

an energy source where its availability can be predicted
9 of 26
Aesthetic
the issue of the appearance of things, e.g. wind farms on the landscape
10 of 26
Viscosity
a measure of the ease with which a fluid can flow
11 of 26
Viscous
a material that doesn't flow quickly
12 of 26
Fissile Fuel
a fuel where the nuclei of the atoms can be split by neutron bombardment, releasing large amounts of energy

Barrage
a dam built across an estuary to generate tidal power
18 of 26
Photovoltaic
a system that converts light into energy
19 of 26

a mirror system that reflects incoming light onto a single point
21 of 26
Potential gravitational energy
the energy of raised position
22 of 26
Coppiced woodland
woodland where the trees are cut to ground level every 3 to 15 years. The regrowing branches can be used as a biofuel
23 of 26
