What You Need to Know
Sous‑vide cooking at 60 °C reduces heat loss by maintaining precise temperature, lowering energy consumption. Solar ovens harness solar irradiance to reach 200 °C, cutting grid electricity use. Anaerobic digestion of kitchen waste converts organic matter into methane‑rich biogas, offsetting energy demand.
The Science
Primary Reaction
Combustion of fossil fuels for cooking and transport, and anaerobic digestion producing biogas.
