This glossary can help you prepare for the IELTS writing tasks related to the Energy use in Environment.
average:
adjective
Constituting the result obtained by adding together several amounts and then dividing this total by the number of amounts.
Example:This chart shows the energy consumption of an average Australian household and how proportion of emitting greenhouse gas in each type of activity.
consumption:
noun
The action of using up a resource.
Example:This chart shows the energy consumption of an average Australian household and how proportion of emitting greenhouse gas in each type of activity.
cooling:
noun
Cooling is removal of heat, usually resulting in a lower temperature and/or phase change.
Example:The last two parts of things are water heating which is the second large source of using energy and the smallest consuming energy one = cooling.
emission:
noun
An emission is something that's been released or emitted into the world.
Example:The second chart shows the percentage of greenhouse gas emissions which result from this energy use.
energy:
noun
Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
Example:This chart shows the energy consumption of an average Australian household and how proportion of emitting greenhouse gas in each type of activity.
greenhouse gas:
noun phrase
A gas that contributes to the greenhouse effect by absorbing infrared radiation. Carbon dioxide and chlorofluorocarbons are examples of greenhouse gases.
Example:The second chart shows the percentage of greenhouse gas emissions which result from this energy use.
marginally:
adverb
To only a limited extent; slightly.
Example:There are just marginally changes in greenhouse gas emissions which grow from 30% to 32% and rise from 2% to 3%.
proportion:
noun
Harmonious relation of parts to each other or to the whole: balance, symmetry.
Example:This chart shows the energy consumption of an average Australian household and how proportion of emitting greenhouse gas in each type of activity.
refrigeration:
noun
The process of subjecting food or drink to cold in order to chill or preserve it.
Example:Using energy for lighting and refrigeration are similar changes in greenhouse gas emissions.
source:
noun
A place, person, or thing from which something originates or can be obtained.
Example:The last two parts of things are water heating which is the second-largest source of using energy and the smallest consuming energy one = cooling.
average:
adjective
