The fuels screen is the place where you can view or edit the list of fuels used in your LEAP analysis. The screen displays a wide range of data about the energy content, density, carbon content, and chemical composition of each fuel and also includes detailed definitional notes and references for the included data (in the bottom two panes of the screen).

The default data provided with LEAP includes a standard fuels database based on IEA, UN and other standard international sources of data. This data should suffice for most LEAP analyses. However, you may wish to edit the data, for example to change the energy contents of certain fuels (especially coal and wood) to reflect the conditions in the Area you are studying. You may also wish to change the names of fuels to reflect the language in which your analysis will be conducted, or edit up to four sets of named fuel groupings which can be used in the Results and Energy Balance views for viewing results summed across these fuel groupings.

Use the Add () button to add a new fuel and the Delete button () to delete a fuel. Note however, that you cannot delete any fuels already in use in your analysis or in use in the TED database. It is recommended that you do not delete fuels in the Fuels database. Click the button to export the fuels database to Microsoft Excel.  Click the ditto button () to duplicate a field value from the value immediately above it.

Some of the data fields in the fuels screen are worth describing in more detail:

By default, the fuels screen is filtered to display only those fuels currently being used in your area. To see the full list of fuels, choose Show: All Fuels. Use the Find box to quickly locate a fuel by name.

You can also sort the display of fuels by name, state, type and category by clicking on the appropriate column title.  A sort indicator is displayed in the column title to show which column is used to sort the table. The indicator shows the sort order using a triangle pointing up for ascending or down for descending sorts.
