Energy calculators

Electricity Cost: Cost = kWh × price per kWh + fixed charge + billed kW × demand charge. Methodology stated, your own inputs only.

Motor Energy Cost: Input kW = rated kW × load ÷ efficiency. Methodology stated, your own inputs only.

Pump Energy Cost: Hydraulic kW = ρ × g × Q × H ÷ 1,000. Methodology stated, your own inputs only.

Fan Power: Air kW = Q × Δp ÷ 1,000. Methodology stated, your own inputs only.

Compressor Cost: Cost = full-load input kW × average load × hours × price. Methodology stated, your own inputs only.

Compressed Air Cost: kW = specific power × flow. Methodology stated, your own inputs only.

Generator Fuel Cost: Fuel = L/h × hours. Methodology stated, your own inputs only.

Solar Output: Output = kWp × peak sun hours × performance ratio × days. Methodology stated, your own inputs only.

Energy Savings Payback: Payback (years) = upfront cost ÷ (kWh saved × price + other yearly savings). Methodology stated, your own inputs only.

Thermal Energy: Q = m × c × ΔT (kJ). Methodology stated, your own inputs only.

Boiler Efficiency: Efficiency = useful heat output ÷ fuel energy input × 100 (direct method). Methodology stated, your own inputs only.
