Biofuels are a form of indirect [[solar energy]], including any fuel that comes directly from biological sources:
 +
 +
*[[Category:Biodiesel]]
 +
*[[Biogas]]
 +
*[[Ethanol]]
 +
*[[Gas pyrolisis]] (wood gas or poor gas)
 +
*[[Biodigesters]]
 +
*[[Methanol]]
 +
*[[Wood]]

Like fossil fuels, biofuels produce [[wikipedia:carbon dioxide|carbon dioxide]]. But unlike fossil fuels, the carbon dioxide produced comes from plants that sucked it out of the air ''last year,'' rather than millions of years ago. This means that biofuels are a form of closed-end [[WikiPedia:recycling|recycling]], whereby the waste product goes directly into production of the fuel.
 +
 +
[[Pollution]] is any byproduct that cannot be fed back into the closed-end system. For biofuels, this includes particulates and unburnt hydrocarbons (smoke), oxides of nitrogen, carbon monoxide, and a few others. These are typically much lower level than when fossil fuel is combusted, but they remain a problem.
 +
 +
What is pollution for one [[technology]] may be the biofuel in another. For example, if wood is heated anaerobically (with limited oxygen), it produces carbon monoxide, which is normally considered a pollutant, but if collected, can be burnt as a biofuel.
