Answer 1

Answer:

biofuel is any liquid fuel derived from biological material such as trees, agricultural wastes, crops, or grass. Biofuel can be produced from any carbon source that can be replenished rapidly, such as plants. Biofuels are used globally and biofuel industries are greatly expanding in Europe, Asia, and North and South America. They contain no sulfur and produce low carbon monoxide and toxic emissions.

Biofuels are substitutes for conventional fossil fuels, such as petroleum, propane, coal, and natural gas. Common U.S. agricultural products including switchgrass and soybeans are specifically grown for biofuel production. Biofuels can reduce greenhouse gas emissions and increase energy security by providing an alternative to fossil fuels. By 2050, biofuels could reduce our greenhouse gas emissions by 1.7 billion tons per year—equivalent to more than 80% of current transportation-related emissions.

Answer 2

Answer:

Biofuel, any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
