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]
The energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density. A biofuel is a fuel produced from recently living organisms. Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline ...
Biofuels compete with retail gasoline and diesel prices which have substantial taxes included. The net result is that it is possible for a farmer to use more than a gallon of fuel to make a gallon of biofuel and still make a profit. There have been thousands of scholarly papers analyzing how much energy goes into making ethanol from corn and ...
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.

Biofuels are different from fossil fuels in regard to carbon emissions being short term, but are similar to fossil fuels in that biofuels contribute to air pollution. Raw biofuels burned to generate steam for heat and power, produces airborne carbon particulates, carbon monoxide and nitrous oxides. [19]
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...
[1] [2] Conversion of biomass to liquid fuels is preferred as an alternative to the extraction of fossil fuels because biomass removes carbon dioxide from the atmosphere as it grows through photosynthesis. When combusted, this carbon is re-released into the atmosphere, closing the carbon cycle and making biofuels carbon neutral under some ...
Fossil fuels have solved two problems which could be separately solved in the future: the problem of a source of primary energy and of energy storage. Along with straight vegetable oil and biodiesel, some energy technologies that could play an important part in the future include:
