Bioenergy is energy contained in living or recently living biological organisms, a definition which specifically excludes fossil fuels. Plants get bioenergy through photosynthesis, and animals get it by consuming plants.
In other words, the energy stored in biomass (organic matter) is called bioenergy. This energy has generally been produced through photosynthesis or is an organic by-product from a waste stream.
Organic material containing bioenergy is known as biomass. Humans can use this biomass in many different ways, through something as simple as burning wood for heat, or as complex as genetically modifying bacteria to create cellulosic ethanol
The materials stored in biological maters can be employed directly for their energy content, when this is so they are referred to as “feedstocks”. Sometimes biological maters produced (grown) in the farms specifically for their bioenergy content (known as “energy crops”), We can also get bioenergy from other sources domestically like animal waste, agriculture, food processing and so on.
Bioenergy materials such as biomass, animal and industrial wastes can be developed or processed to give incredible end product to meet our demand for energy. An example of such end product is gas for cocking, transportation fuels and electricity It is also classified as a form of renewable energy derived from biodegrdable organic material
Bioenergy continues to provide important sources of energy in many parts of the world. Bioenergy is the dominant energy source for most of the world’s population who live in extreme poverty and who use this energy mainly for cooking. More advanced and efficient conversion technologies now allow the extraction of biofuels – in solid, liquid and gaseous forms – from materials such as wood, crops and waste material. This chapter provides an overview of biofuels. What are they, what is their potential and what are their implications for agriculture? The main focus, however, is on liquid biofuels for transport, which are now gaining in prominence as a result of the rapid increase in their use.
