DG vs Solar Carbon Savings

What replacing generator hours with solar+battery saves — carbon and cash.

Diesel self-generation costs ₹25–35/kWh all-in and 0.8 kg CO₂e/kWh — the most expensive, dirtiest power most Indian businesses buy. Enter the DG fuel bill; the 10%-reduction row scales linearly to whatever share solar+storage displaces.

Every DG litre avoided by solar+storage saves 2.68 kg CO₂e and ₹25–35/kWh in true generation cost. Every unit of diesel (l) burned releases 2.68 kg CO₂e (IPCC default, combustion only). Fuel emissions and fuel bills fall together — the business case and the carbon case are the same case.

Frequently asked questions

How much CO₂ comes from a litre of diesel or petrol?+

Diesel: 2.68 kg CO₂e/L; petrol: 2.31; LPG: 2.98/kg; CNG: 2.75/kg; coal: ~2.42/kg (grade-dependent) — IPCC combustion defaults. Multiply by your purchase volume and the Scope 1 line writes itself. The carbon is fixed chemistry; only the volume is negotiable.

Why track fuel emissions monthly instead of annually?+

Because fuel is bought monthly and decisions are made monthly: a generator running long this month shows up now, not in a year-end surprise. Monthly lines also build the evidence trail (invoices ↔ entries) that assurance and audits sample.

What's the fastest way to cut fuel emissions?+

Displace, then improve: solar+storage against generator hours, electric against ICE kilometres, heat pumps or biomass against boiler fuel — displacement zeroes the line. Where the fuel must stay, maintenance and load management deliver the 10–20% the reduction row prices.

Do these factors include upstream (well-to-tank) emissions?+

No — combustion only, the Scope 1 convention. Upstream extraction/refining/transport adds ~15–25% but belongs in Scope 3 category 3. Keep the boundaries clean: this number is defensible precisely because it claims only what your chimney emits.
