Free Tools
Practical, free tools to help you understand your energy costs and emissions on a like-for-like basis. Pick a tool below to get started.
Choose a calculator
Compare what you pay across fuels, cost and emissions, side by side
Enter what you pay for any fuels below, or prefill with current market prices for your region. Everything converts to a common $/GJ basis so you can see the true cost of delivered energy, alongside the carbon emissions of each.
Cost ranking ($/GJ, lower is cheaper)
Enter at least one price to compare.
Carbon ranking (kg CO₂-e/GJ, lower is cleaner)
Enter at least one price to compare.
EnergyDesk Insight
Conversions use NGA energy content factors (electricity 3.6 MJ/kWh, diesel 38.6 MJ/L, LPG 25.7 MJ/L, coal ≈ 27 GJ/tonne) and combustion emissions factors (gas 51.4, LPG 60.2, diesel 70.2, coal 90.2 kg CO₂-e/GJ; electricity uses an indicative grid Scope 2 factor of 68 kg CO₂-e/GJ). Indicative only. For a tailored analysis, request a custom report →. Factors per the National Greenhouse Accounts ↗.
Estimate your annual Scope 1 & 2 emissions from energy use
Enter your annual consumption for each fuel you use. The calculator applies NGA emissions factors to estimate your total annual emissions in tonnes of CO₂-e.
Estimated total annual emissions
0.0 t CO₂-e
Emissions factors: electricity Scope 2 ≈ 0.68 kg CO₂-e/kWh (national indicative, varies by state), gas 51.4 kg/GJ, diesel 2.71 kg/L, LPG 1.55 kg/L. Indicative only and not a substitute for formal NGER reporting. Factors per the National Greenhouse Accounts ↗.
Convert between common energy units instantly
Enter a value and choose its unit, the equivalent in all other common energy units is shown below. Useful for reconciling bills, contracts and equipment specs that use different units.
Standard energy conversions. 1 kWh = 3.6 MJ · 1 GJ = 1000 MJ · 1 therm = 105.5 MJ · 1 MMBtu = 1055.06 MJ.
Estimate the fuel energy and cost to raise process steam
Estimate the fuel energy needed to generate steam, accounting for boiler efficiency. Enter your steam output, efficiency and (optionally) a fuel price to see running cost.
Estimated fuel requirement
Enter your steam output to calculate.
Assumes a net enthalpy rise of ~2.34 GJ per tonne of steam (saturated steam at low pressure from ~85°C feedwater). Actual figures vary with pressure, feedwater temperature and blowdown. Indicative only.
Estimate annual generation, bill savings and payback for a rooftop solar system
A high-level estimate of what a rooftop solar system could generate and save. For indicative guidance only, a detailed assessment should account for your load profile, roof orientation and feed-in tariff.
Estimated solar performance
Enter system size and electricity price to calculate.
Generation estimates use indicative annual yields per kW by state (NSW ~1,380 kWh, VIC ~1,250, QLD ~1,500, SA ~1,450, WA ~1,550, TAS ~1,100). Assumes ~80% of generation offsets grid consumption. Indicative only; excludes STCs, feed-in tariffs and degradation.
Model the full cost and emissions impact of switching your boiler, kiln or fleet from one fuel to another, including capital payback and carbon reduction over time.
In developmentSee how your energy rates stack up against regional market benchmarks for businesses of your size and sector, so you know whether you're overpaying.
In developmentWork out how quickly an energy-saving investment pays for itself
Enter the upfront cost of an upgrade (LED lighting, a more efficient boiler, insulation, solar, etc.) and the annual saving you expect. The calculator shows simple payback, return on investment and total savings over the equipment's life.
Payback & return
Enter a cost and annual saving to calculate.
Simple payback ignores discount rates, inflation and maintenance. For a full investment case including these factors, request a custom report →.
Our custom reports go beyond the calculators, benchmarking your costs, modelling fuel switches, and mapping your carbon obligations with practical tactics to reduce both.
