Energy in the future? A sustainable alternative-bioethanol Xiang Gu Department of Computer Science,The School of Electronic Information and Electrical Engineering,Shanghai Jiao Tong University,Shanghai 200240,China Abstract Over the past decades,biotechnology-based fuel has attracted more and more attention.Bioethanol is a standing-out example of it.It has been made easy and available to produce commercial bioethanol in large amounts as well as refined quality.In addition,bioethanol abandons the harmful effects of traditional fossil fuels like air pollution and non-sustainability,and in nature brings several advantages with it,which makes it possible and promising to be the clean energy of the future. Keywords:bioethanol;large amounts and high quality;clean energy 1.Introduction For the past four decades after the massive and constructive reform of technology,majorly represented by the invention and usage of electricity and steam machine,energy has become a serious strategic issue for all countries in the world.At the same time,problems like air pollution and elimination of natural resource have prompted people to seek a better alternative forEnergy in the future?
