The use of ethenol has really grown recently. Just in the years since we've begun building our house, I've seen many more flex-fuel vehicles, and the "E85" signs at petrol stations are increasingly common.
Sweden is also leading on obtaining their ethanol from better sources. The most common sources are food crops (such as grains), or importing from sugar cane sources (Brazil being the main supplier). Sweden is working on 'secondary' sources of ethanol, such as waste material or cellulose-based crops. Both of these approaches are more sustainable and environmentally friendly.
