Biodiesel (Greek, bio, life + diesel from Rudolf Diesel) refers to a diesel-equivalent, a processed fuel derived from a biological source. Biodiesel is the common name for a variety of ester-based oxygenated fuels [6] from renewable biological sources. It can be made from processed organic oils and fats.
One possibility to overcome the problem is the cultivation of micro-algae and switching to third generation biofuels, which seem to be a promising source since algae are able to efficiently convert sunlight, water, and CO 2 into a variety of products suitable for renewable energy applications. Therefore, this review is intended to recapitulate ...
Biofuels may have fewer effects on the enviroment than fossil fuels. Production and use of biofuels is considered by the U.S. government to have fewer or lower negative effects on the environment compared to fossil-fuel derived fuels. There are also potential national economic and security benefits when biofuel use reduces the need to import ...
However, there are a number of issues raised by the production and use of biofuels that directly contradict their status as a renewable energy source. When burned, biofuels produce fewer emissions, a reason why they are seen as a preferable alternative to traditional fuels. However, the production of biofuels often involves using land already ...
Despite this, the existing evidence suggests that, if no land-use change (LUC) is involved, first-generation biofuels can—on average—have lower GHG emissions than fossil fuels, but the reductions …
Biomass is an organic renewable energy source that includes materials such as agriculture and forest residues, energy crops, and algae. Scientists and engineers at the U.S. Department of Energy and its national laboratories are finding new, more efficient ways to convert biomass into biofuels that can take the place of conventional fuels like …
WASHINGTON – Today, the U.S. Environmental Protection Agency (EPA) issued a final rule under the Renewable Fuel Standard (RFS) program that establishes the biofuel volume requirements for 2023 to 2025. This final rule builds on the RFS program''s progress over the previous two years and reflects the Biden-Harris Administration''s …
