bioenergy and agrofuels
Similar to how cavemen used burning wood to keep warm, bioenergy employs the breakdown of recently living biomaterials to harvest the stored energy. Examples of recently living biomaterials include wood/food waste, forest residues, or microalgae. This breakdown has become known as biomass. Three methods "to harvest biomass are through burning, bacterial decay, and conversion to gas or liquid fuel" (Energy.gov, n.d.). Biomass can be used in a variety of forms. Some of the most notable are biofuels for vehicles or heat and electricity. The alternative source offers a renewable, cost-effectiv,e and efficient approach to our energy crisis.

Agrofuels and bioenergy
Bioenergy is a type of renewable energy resource primarily obtained from biomass, comprising living organic matter, which is used to produce fuels, electric power, and different products that meet most human energy demands. On the other hand, agrofuels, for example, firewood, bioethanol, and biogas, are fuels obtained from plant-based matter rather than oil. This essay argues that although biofuels are usually perceived as eco-friendly, their adoption as biofuels energy alternatives has several negative consequences.
According to Guo and others., biofuels can be categorized into solid forms that include charcoal and firewood, liquid agrofuels such as bioethanol and biodiesel, and gaseous biofuels, for example, biogas (712-725). They predicted that the adoption of biofuel and bioenergy would significantly increase by meeting approximately more than 30% of human energy demands (Guo et al. 712-725).
Jeswani and others believe that biofuels and bioenergy generally are eco-friendly since they are fuel alternatives containing low levels of carbon; thus, they can reduce the overall production of greenhouse gases. However, shifting to biofuels has several negative outcomes. Firstly, growing crops primarily for energy production exerts unnecessary pressure on land since it will encourage deforestation and misuse of natural resources such as water (Jeswani et al.). Higher demand for agricultural products for energy production will result in clearing forests to find more land, using fertility chemicals, and resource misuse to meet the high human energy demand, substantially increasing food prices (Jeswani et al.). Further, although biofuels use is considered environmental-friendly, it can be associated with higher production of greenhouse gases and carbon emissions (Jeswani et al.). Generally, although biofuels have potential benefits since they are derived from plant-based matter, they can equally be linked with potential environmental risks.
In conclusion, bioenergy involves the production of energy from renewable sources. Biofuels are fuels obtained primarily from pant matter; thus, certain people perceive them as environmental-friendly. However, this is not the case since they can be associated with multiple downsides such as the production of greenhouse gases, deforestation, exploitation of natural water sources, and a significant rise in food prices; Thus, their adoption should be regulated.
