The A-Z of Global Warming: Biofuels discusses the relevance of biofuels to global warming, what they are, what they are used for, and whether they are good for the environment.

Just how long do we have until we run out of fossil fuels? There are many studies that address this question and there is general agreement as when these energies are depleted.

This article is taken from The A-Z of Global Warming, a book on all issues relating to global warming and climate change written in unique A-Z format. The Article is first in a series of extracts from the book, to be published in May 2008.

This article discusses the potential for and implications of coal gasification and coal-to-liquids alternative energy initiatives.

The article deals with the efficiency of ethanol as motor fuel and with its ability to contribute to a reduction in global warming. Fossil fuels are the major contributors to global warming and resulting climate change. They must be replaced by carbon-neutral motor fuels very soon. Ethanol is being promoted in the USA as a major contributor to the reduction of greenhouse gas emissions and control of global warming. These claims are disputed.
