In today''s world, the development of alternative sources of energy is becoming more necessary in order to solve the global problems of energy supply, climate change and other environmental issues. However, as some of these processes are in their early stages, their feasibility and impacts are not possible to measure. In the case of biofuels, the new generations are being heavily criticised whilst they are being researched. This book brings a series of articles about the second-generation biofuels, analysing their repercussions in economic, technological and environmental fields. The book also presents an analysis on scientific and environmental journalism, discussing the role of the media in society; the role of science and environmental reporting; the problems journalists face; the challenges posed by the increasingly commercial media; and interviewing journalists to learn how they deal with their work environment challenges. This discussion is of public interest and could be useful to several groups, from Journalists —as well as Journalism students— to Environmentalists, Scientists and their respective Public Relations.
