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 ]
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.
Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass , which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [ 1 ]
The surface power production densities of a crop will determine how much land is required for production. The average lifecycle surface power densities for biomass, wind, hydro and solar power production are 0.30 W/m 2, 1 W/m 2, 3 W/m 2 and 5 W/m 2, respectively (power in the form of heat for biomass, and electricity for wind, hydro and solar ...
In 2008, recognizing the need to diversify its sources of energy and reduce emissions, Mexico passed a law to push developing biofuels that don't threaten food security and the agriculture ministry has since identified some 2.6 million hectares (6.4 million acres) of land with a high potential to produce jatropha.

The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil. [18] From 2005 to 2007 a number of types of vegetable oil have doubled in price. The rise in vegetable oil prices is largely attributed to biofuel demand. [19]
Most ethanol plants rely on natural gas to power their processing equipment. The process to be used at the Emmetsburg plant will enable the plant to make 11% more ethanol by weight of corn and 27% more by area of corn. The process cuts the need for fossil fuel power at the plant by 83% by using some of its own byproduct for power.
The Environmental Protection Agency plans to finalize biofuel blending volumes at 20.94 billion gallons in 2023, 21.54 billion gallons in 2024 and 22.33 billion gallons in 2025, the sources said. Th
