Cooking Energy Crisis: Tradeoff Analysis

1) Baseline assumptions

Cooking usage (typical household)

  • 2–3 meals/day
  • Induction active heating time ≈ 1.5–2 hours/day

We’ll take:

  • 1.75 hours/day average

Your device

  • 1600 W → 1.6 kW

Tariff (from earlier)

  • Effective: ₹5–₹6/unit
  • With charges: ₹6–₹7/unit all-in

2) Monthly electricity cost (induction)

Energy per day

  • 1.6 kW × 1.75 h = 2.8 kWh/day

Monthly consumption

  • 2.8 × 30 = 84 units/month

Cost

  • At ₹6/unit → ₹504
  • At ₹7/unit → ₹588

? Induction monthly cooking cost: ₹500 – ₹600


3) LPG cost equivalent

Standard LPG cylinder

  • ~14.2 kg
  • Goa price typically: ₹900–₹1100

Consumption pattern

  • Average household:
    • 1 cylinder lasts 25–40 days

We’ll normalize:

ScenarioMonthly LPG cost
Efficient usage₹700
Average₹900
Heavy cooking₹1100

4) Direct comparison

5) Trade-off analysis (important)

Efficiency

  • Induction converts most energy → heat
  • LPG loses heat to surroundings
    ? Induction wins structurally

Cost predictability

  • Electricity tariffs change slowly
  • LPG prices fluctuate with global markets
    ? Induction more stable long-term

Practical constraints

  • Induction:
    • Needs compatible cookware
    • Power outages affect usage
  • LPG:
    • Works anytime
    • Better for high-heat cooking (e.g., roti, wok)

6) Hybrid strategy (most optimal in reality)

Most efficient households do:

  • Induction for:
    • Boiling, rice, dal, reheating
  • LPG for:
    • Roti, frying, heavy cooking

? This typically reduces LPG usage by 30–50%


7) Final conclusion

  • Pure induction cooking: ~₹500–₹600/month
  • Pure LPG: ~₹700–₹1100/month
  • Best real-world strategy: Hybrid → lowest cost + flexibility

Bottom line

From a cost + efficiency + resilience perspective:

Induction is economically superior for daily cooking,
but LPG remains valuable as a complementary system.
