These include lipids such as vegetable oils, animal fats, greases, and algae and cellulosic material such as crop residues, woody biomass, and dedicated energy crops. Currently, the United States has limited commercial-scale production of renewable hydrocarbon biofuels. Where production is occurring, the commercial facilities largely focus on renewable diesel production.
As of , there were four commercial renewable diesel plants with a combined capacity of million gallons and one renewable jet fuel plant with a capacity of 42 million gallons. One plant is under expansion and two are under construction, which are expected to add another million gallons of capacity. The United States continues to import renewable diesel, largely from production facilities in Singapore.
Researchers are exploring a variety of methods to produce renewable hydrocarbon biofuels. Production plants may be stand-alone or co-located at petroleum refineries. Engine and infrastructure compatibility —Renewable hydrocarbon biofuels are chemically identical to their petroleum counterparts and therefore minimize compatibility issues with existing infrastructure and engines. Increased energy security —Renewable hydrocarbon biofuels can be produced domestically from a variety of feedstocks and contribute to U.
Fewer emissions —Carbon dioxide captured by growing feedstocks reduces overall greenhouse gas emissions by balancing carbon dioxide released from burning renewable hydrocarbon biofuels compared with conventional fuels.
More flexibility —Renewable hydrocarbon biofuels are replacements for conventional diesel, jet fuel, and gasoline, allowing for multiple products from various feedstocks and production technologies.

Biodiesel Biodiesel is a renewable fuel which can be made from vegetable oils, animal fats, or recycled restaurant grease. Electricity Electric cars have been around a while but so far have struggled to enter the mass market. Ethanol Ethanol is an alcoholic renewable that is made of the same kind of alcohol you find in alcoholic beverages. Hydrogen Hydrogen has virtually no greenhouse gas emissions.
Natural Gas Natural Gas is already widely used for a number of purposes around the world. Propane Propane, or liquefied petroleum gas, is clean-burning and high-energy, making it a tempting alternative.

Biodiesel is cleaner than petroleum. Further, its domestic production creates a benefit for local and national economies. On the flip side, biodiesel is significantly more expensive than petroleum-based diesel and can cause fuel filter problems for vehicles.
Ethanol, or ethyl alcohol, is another renewable fuel and is commonly produced from plant material, especially corn. Nearly all gasoline sold in the US contains at least a low percentage of ethanol E10 , and high-ethanol blends exist E85 for vehicles capable of using it.
