Biofuel Basics - Department of Energy
Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.
Ethanol explained - U.S. Energy Information Administration (EIA)
In the United States, nearly all fuel ethanol is produced from corn kernel starch, which is considered a conventional biofuel under the U.S. Renewable Fuel Standard Program (RFS). Ethanol has other potential sources aside from fermentating grain starch and sugars.
Biofuels explained Ethanol - U.S. Energy Information Administration …
Total annual fuel ethanol production generally increased each year from 1981 through 2022. In 2022, U.S. fuel ethanol production (as measured by renewable fuels and oxygenate plant net production of fuel ethanol) was about 15.4 billion gallons (about 0.4 billion barrels).
Ethanol vs. Petroleum-Based Fuel Carbon Emissions
Jun 23, 2022 · Biofuels have been proven to emit significantly lower greenhouse gas (GHG) emissions than petroleum-based fuels, and recent scientific studies indicate that net-zero emission biofuels are not only possible, but achievable. Corn ethanol and other biofuels.
Biofuel | Definition, Renewable Energy, Types, & Pros and Cons
Oct 19, 2024 · Biofuel is commonly advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels, particularly within the context of rising petroleum prices and increased concern over the contributions made by fossil fuels to global warming.
Biofuels, from ethanol to biodiesel, facts and information
Jul 15, 2019 · Much of the gasoline in the United States contains one of the most common biofuels: ethanol. Made by fermenting the sugars from plants such as corn or sugarcane, ethanol contains oxygen that...
Bioenergy Basics - Department of Energy
Biomass is one type of renewable resource that can be converted into liquid fuels—known as biofuels—for transportation. Biofuels include cellulosic ethanol, biodiesel, and renewable hydrocarbon "drop-in" fuels.
Ethanol Fuel Basics - Alternative Fuels Data Center
Ethanol is a renewable fuel made from various plant materials collectively known as "biomass." More than 98% of U.S. gasoline contains ethanol to oxygenate the fuel. Typically, gasoline contains E10 (10% ethanol, 90% gasoline), which reduces air pollution.
What are the Pros and Cons of Ethanol Biofuel?
Jul 23, 2019 · Biofuels like ethanol might help fight climate change. But they can contribute to food insecurity and greenhouse gases in ways that might surprise you.
Biofuels Factsheet | Center for Sustainable Systems
Ethanol, an alcohol blended with gasoline for vehicle fuel, is the most produced (82%) and used (75%) biofuel in the U.S. 2; The U.S. and Brazil produced 80% of the world’s ethanol in 2022. 3 94% of U.S. ethanol is derived from corn 4, while Brazil uses sugarcane as feedstock 4.
