  2. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    Ethanol fuel is the most common biofuel worldwide, particularly in Brazil. Alcohol fuels are produced by fermentation of sugars derived from wheat , corn , sugar beets , sugar cane , molasses and any sugar or starch from which alcoholic beverages such as whiskey , can be made (such as potato and fruit waste, etc.).

  3. Issues relating to biofuels - Wikipedia

    en.wikipedia.org/wiki/Issues_relating_to_biofuels

    Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...

    An ethanol fuel plant under construction, Butler County, Iowa. Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views and is a long-standing, controversial one in the literature.

    Biofuel production shall contribute to the social and economic development of local, rural and indigenous peoples and communities. Biofuel production shall not impair food security. Biofuel production shall avoid negative impacts on biodiversity, ecosystems and areas of high conservation value.

  6. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    Microalgae-biofuel production costs a larger amount of money compared to fossil fuel production. The cost estimation of producing microalgae-biofuel is around $3.1 per litre ($11.57/US gal), [55] which is considerably more expensive than conventional gasoline. However, when compared with electrification of the vehicle fleet – a key advantage ...

    These systems may have other negative side effects. There is however presently no need to expand the use of biofuels in energy or industry applications to allow for BECCS deployment. There is already today considerable emissions from point sources of biomass derived CO 2, which could be utilized for BECCS. Though, in possible future bioenergy ...

  8. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    The IPCC states that the net climate effect from conversion of unmanaged to managed forest can be positive or negative, depending on circumstances. The carbon stock is reduced, but since managed forests grow faster than unmanaged forests, more carbon is absorbed. Positive climate effects are produced if the harvested biomass is used efficiently.

  9. Bioenergy - Wikipedia

    Biodiesel is produced from the oils in for instance rapeseed or sugar beets and is the most common biofuel in Europe. [citation needed] Second-generation biofuels (also called "advanced biofuels") utilize non-food-based biomass sources such as perennial energy crops and agricultural residues/waste.
