In face of the increasingly obvious need to ensure the
sustainability of the environment, alternative and renewable energy
sources are no longer just the concern of environmentalists and
have become commitments of governments virtually everywhere in the
world. In this context, ethanol emerges as an excellent substitute
for petroleum derivatives. This green alternative fuel is sustained
by its own burning because when CO2 serves as a carbon source for
the growth of plants, it will allow the carbohydrates to be
fermented. In addition, currently different generations of this
fuel are being proposed, considering the utilization of their own
waste. However, challenges still need to be overcome to enable the
second, third and fourth generations of ethanol. At the same time,
other renewable fuel alternatives emerge to compete with it. The
automobile industry, for example, has been developing new engines,
hybrids or not, that can be powered by electricity or H2. In this
regard, this book addresses, under different aspects, the main
strategies to surpass the remaining obstacles, as well as the
advantages and disadvantages of ethanol as a fuel of the future. In
this context, the "Ethanol as a Green Alternative Fuel" book shows
present and future scenarios about bioethanol and perspective in
their chain, considering the economic and environmental impact
mitigations approach.
