Original text

A biofuel is a type of fuel whose energy is derived from biological carbon fixation. Biofuels include fuels derived from biomass conversion, as well as solid biomass, liquid fuels and various biogases.^[1] Biofuels are gaining increased public and scientific attention, driven by factors such as oil price hikes and the need for increased energy security. However, according to the European Environment Agency, biofuels address global warming concerns only in specific cases.^[2]

Revised text

A biofuel is a fuel that uses energy for from a carbon fixation. Basically these fuels are produced from living organism. Examples of this carbon fixation are plants and microalgae. These fuels are made from a biomass conversion. Biomass refers to recently living organisms, most often referring to plants or plant-derived materials. This biomass can be converted to energy in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion’s can be in solid, liquid, or gas form. This new biomass can be used for biofuels. Biofuels have increased in popularity because of the raising oil prices and need for energy security.
