COMPARATIVE FUEL COSTS and
CARBON EMISSIONS
Liberalisation of the fuel
market has led to huge variations in fuel costs and great
difficulty in making general comparisons. SOLIFTEC provide this
spreadsheet for you to enter your own local costs and generate a
comparative chart. An example result is given below.
Download
the SOLIFTEC Comparative Fuel Cost Spreadsheet as XLS Spreadsheet
NOTES:
Wood, although considered carbon-neutral carries a small carbon
overhead in the non-renewable energy required to process it.
Chart results represent energy costs only - costs of running,
renewing, servicing and repairing equipment are not included.
'Useful' heat is heat actually emitted to room, allowing for
efficiency losses
One example of the sort of
chart which can be produced.
