Question

Types of bioenergy are
(A) Biomass
(B) Biofuel
(C) Biogas
(D) All of the above

Answer 1

Hint: There are many kinds of sources of bioenergy. Some of them are a renewable source of energy which is obtained from plants and animals and some are known to be the fuel that is derived from biomass.

Complete answer:
Biomass is known as the amount of organic matter which is present in an organism at a given time. It's the stored sort of energy in any type of organism.
Biofuel is any substance that features a biological origin and may be used as a fuel. For instance, fuelwood.
Biogas is made from the decomposition of organic matter and may be used as an alternate source of energy in situ of fossil fuels.
The energy produced from these sources is named bioenergy which is renewable and has no negative impact on the environment.
Bioenergy refers to electricity and gas that's generated from organic matter, referred to as biomass. this will be anything from plants and timber to agricultural and garbage – and even sewage.
Burning biomass does release ${ CO }_{ 2 }$. But, because it releases an equivalent amount of carbon that the organic matter wants to produce, it is absorbed while it grows, it doesn’t break the carbon balance of the atmosphere.
In comparison, burning fossil fuels releases ${ CO }_{ 2 }$ that has been locked away for many years, from a time when the earth’s atmosphere was very different. This adds more ${ CO }_{ 2 }$ into our current atmosphere, breaking the carbon balance.
The overall sustainability and environmental benefits of bioenergy can depend upon whether waste feedstocks or energy crops are getting used.

So, the correct answer is ‘All of the above’.

Note:
-Sugarcane is the feedstock in the production of bioethanol from the fermentation of the sugars present in it.
-Sugarbeets and tapioca can also be used for the production of bioethanol.
-Energy crops can be genetically modified to provide higher yields like more biomass.
