The production of biofuels can be very energy intensive, which, if generated from non-renewable sources, can heavily mitigate the benefits gained through biofuel use. A solution proposed to solve this issue is to supply biofuel production facilities with excess nuclear energy, which can supplement the power provided by fossil fuels. [112]
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Biofuels are also considered a renewable source. Although renewable energy is used mostly to generate electricity, it is often assumed that some form of renewable energy or a percentage is used to create alternative fuels. Research is ongoing into finding more suitable biofuel crops and improving the oil yields of these crops.
Biofuels are liquid, renewable energy sources created by converting the energy stored in organic matter like plants or agricultural waste, also known as biomass into fuel.
A biofuel made from waste or inedible vegetation, with renewable energy to power the production, would have little or no greenhouse gas emissions, making it a clean fuel.
The most economical source of carbon for recycling into fuel is flue-gas emissions from fossil-fuel combustion where it can be obtained for about US$7.50 per ton. [ 7 ] [ 19 ] [ 13 ] However, this is not carbon-neutral, since the carbon is of fossil origin, therefore moving carbon from the geosphere to the atmosphere.
The EU Renewable Energy Directive requires that the lifecycle greenhouse gas emissions of biofuels consumed be at least 50 percent less than the equivalent emissions from gasoline or diesel by 2017 (and 35 percent less starting in 2011). Also, the feedstocks for biofuels "should not be harvested from lands with high biodiversity value, from ...
However, unlike traditional gasoline, which are fractionally distilled from crude oil and thus are non-renewable fossil fuels, biogasolines are renewable biofuels made from algal materials, energy crops such as beets and sugarcane, and other cellulosic residues traditionally regarded to as agricultural waste.
