Your letter: On the greenhouse effect

C.G. Moghe is well justified in calling for a careful discussion of Indonesia's biofuel drive (The Jakarta Post, March 6), but some scientific clarification is required in the interests of informed debate. In particular, his concern about additional waste heat from burning biofuels, thus adding significantly to the greenhouse effect, is based on a misunderstanding and is therefore misleading. Waste heat is notbad as the greenhouse gases" emitted from burning fossil fuels.
