A lternative fuels: sources of energy that are relatively rare today, such as solar and wind energy.

Carbon dioxide: a trace gas in the atmosphere that is believed to contribute to global warming; it is formed when carbon-rich fuels combine with oxygen in the air through combustion.

Carbon sequestration: the process by which trees, other vegetation, and soil hold carbon in the form of plant matter, preventing the formation of carbon dioxide.

Carbon sinks: plants or other material, such as soil, that absorb and retain carbon.

Carbon tax: a tax placed on fuel, based on the amount of carbon in the fuel; it is designed to discourage the use of fuel that produces carbon dioxide.
