Alternative Energy

Biodiesel is an alternative fuel produced from renewable resources such as plant oils, animal fats, used cooking oil, and new sources such as algae. Biodiesel contains no petroleum, but can be combined in any quantity with petroleum diesel to create a biodiesel blend. Biodiesel blends can be used in most "compression-ignition" (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics (the "diesel" odor). (Biodiesel is not raw vegetable oil.)

Emissions trading or cap and trade is usually a government-mandated, market-based approach to controlling pollution by providing economic incentives for achieving reductions in the emissions of pollutants.


This is often associated with carbon trading to allow polluters to 'offset' their pollution by buying equivalent carbon credits.
