5 Environmental Effects and Tradeoffs of Biofuels

5. Environmental Effects and Tradeoffs of Biofuels. Petroleum extraction, transport, refining, and combustion have many known negative environmental effects, including disruption of sensitive ecological habitats and high greenhouse-gas (GHG) emissions.Biofuels, too, have their environmental costs (NRC, 2003, 2010a), but displacing petroleum-based fuels with biofuels can reduce the nations

Energy-Intensive Industry - an overview | ScienceDirect Topics

Based on gas turbine technology, this is a way in which to substantially reduce the primary energy needs for steam making. Low- and medium-pressure steam can be generated in a waste heat boiler using the flue gases of a gas turbine. Classic cogeneration systems are based on the use of a steam boiler and a back pressure turbine.
