Description of model
|
WEM is a large-scale mathematical model
designed to replicate how energy markets function. The model is made up of six main modules: final
energy demand; power generation; refinery and other transformation; fossil-fuel supply; CO2 emissions
and investment. Its main relevance to the response measures is its use for assessing policy
changes and, in particular, changes in technology patterns.
The model is mainly used for: 1) analysing global energy prospects; 2) estimating the
environmental impact of energy use; 3) analysing the effects of policy actions and technological
changes; and 4) estimating investment in the energy sector.

|
Particular relevance
|
The WEM is relevant in analysing the development and diffusion of less carbon-intensive
technologies, given activities in energy markets.
