Bioenergy is renewable energy that is produced from biological sources, biomass, which can be used for heat, electricity and transportation fuel, and associated co-products. Biofuel refers to liquid fuels produced from biomass (see FAO 2008 for further information).
Commercially established sources of biofuel today are crops such as soy, palm oil, sugar cane, or corn, often referred to as ' first-generation' biofuels. Biofuels produced from lignocellulosic biomass derived from non-food or food crop co-products (such as straw) are referred to as 'Second-generation' Biofuels. These need further biotechnological and commercial development.
Although bioenergy has been used for centuries, recent commercial biofuel manufacture and the development of biotechnologies to support new forms of production have raised a wide range of social and ethical aspirations and concerns.
The types of issues include a number of notable social issues, with the use of biofuels having the potential to substantially change current energy, agricultural and land use practices and policies. The issues raised by biofuels are exemplified by the increasing controversy (reflected by widespread media coverage and debate) surrounding the use of arable land for fuel production and the resultant impact that this may have on food supply and pricing.
Within in this case study, each of these approaches will be mapped and examined. Claims made that this type of engagement with issues and wider reflection can promote the search for new ideas and solutions within the research community will also be examined.
