Sustainable Ethanol: The Future of Energy Production?

Sustainable Ethanol: Biofuels, Biorefineries, Cellulosic Biomass, Flex-Fuel Vehicles, and Sustainable Farming for Energy Independence

We hear a lot these days about global warming, the West's over consumption habits, and how oil is getting more and more expensive and less available. We also hear a lot about alternative energies, flex-fuel cars, ethanol, and the like, but how many of us really know what these alternatives mean - both for the environment and our wallets. Unless you are a scientist working in the field, often we have to rely on what the media tells us; and many of us don't trust the media for a straight forward, objective opinion. Big oil, with their record profits, try and keep us in the dark about other forms of energy. Good thing I stumbled upon the book Sustainable Ethanolby the Goettemoeller brothers. This is the first book I have seen that explains the science - and logic - behind ethanol as an alternative fuel to oil and gas in a clear, readable, and informative style.

Not only do they cover the history of ethanol fuel (did you know the first cars were designed to run on ethanol, not gasoline), but they go into what the latest scientific studies prove - that ethanol is a viable alternative fuel not only for cars, but also for other forms of energy such as natural gas. This latter point is further developed in the book when the Goettemoeller brothers delve into biogas and butanol - two other alternative energies that can be derived from natural resources (such as landfills, manure, and agricultural waste).

Chapters include: A brief history of ethanol fuel; Will cheap oil return?; Economic and security benefits; Environmental impact; E10, E85, and flex-fuel vehicles; Improving fuel economy on ethanol; Food, farming, and land use; Ethanol production; Cellulosic ethanol; Energy balance: Is ethanol renewable?; and Facing our energy future.

Some highlights of the book include:

In 2006 the ethanol industry contributed $23.1 billion to our Gross Domestic Product, created 163,034 new jobs, $2.7 billion in federal tax revenue, $2.2 billion in state tax revenue, and reduced our need for foreign oil imports by 206 million barrels.

If car manufacturers optimized their flex-fuel vehicles to run on E85 (85% denatured alcohol and 15% gasoline), not only would the fuel economy be the same as straight gasoline, but a significant reduction in pollution would occur because ethanol has fewer highly volatile components (i.e., lower carbon monoxide and carbon dioxide).

Ethanol production is not limited to just corn: grain sorghum, wheat, barley, agricultural residues, forestry wastes, municipal solid wastes, food processing and other industrial wastes, and various grasses can all be used to make ethanol.

Ethanol can be made via a "closed loop" system, whereby the grain used to make the ethanol can then be feed back to the animals (as ethanol production only uses the starch from grains, not the proteins or vitamins), the manure from the animals is then used to create fertilizer (for more grain) and biogas which is used as a process fuel in place of natural gas. In a sense, no external energy is required to go into the process, creating a sustainable energy production process.

Sustainable Ethanolis copiously documented, with charts and graphs illustrating the complex science that is clearly explained. This book should be on everyone's reading list who cares about the environment and our future. Rarely does one get to read about an emerging technology and actually understand at the end what that technology is, how it works, and just how important it can be for helping save the planet. The Goettemoeller brothers have succeeded beyond any expectations in this regard. Sustainable Ethanolis a landmark book - if you want to see what you can do to help save the planet, then this book is a must.
