Question

The energy obtained from biological resources is called a:
 A) Electrical energy
B) Mechanical energy
C) Bioenergy
D) Life energy

Answer 1

Hint: It is a renewable form of energy that is formed from biologically derived material. It is used in many fields very efficiently and also it is a very cheap source of energy and also it does not harm the environment.

Complete answer:Bioenergy is the renewable form of energy which is derived from the sources like Biomass, Firewood, biogas, biodiesel, ethanol production, and algal hydrogen factory.
Non - Renewable source: a source of energy whose quantity is fixed and reduced with its consumption so ultimately they finished due to their extravagant consumption Example: fossil fuel and nuclear energy sources.
Renewable sources: a source of energy that is regenerated and not reduced with its consumption.
Example: solar energy, wind energy, tidal energy, and bioenergy.
Energy consumption is 82% from non-renewable sources and 18% from renewable sources, 11% comes from Bioenergy.
Hence option C is correct.
Sources of renewable energy are:
1) Biomass- with the help of sunlight plants perform photosynthesis and fix carbon which forms their biomass and this is consumed by animals and forms their biomass.
So we can say that the ultimate source of bioenergy is the sun.
2) Firewood: In simple terms, firewood is wood used for fire. (which has high combustion power, higher calorific value, and also produces less amount of smoke).
3) Biogas: it is the mixture of gases (like methane, carbon dioxide, hydrogen sulfide) which is produced by the microbial university and it is also used as the fuel
Biodiesel: Diesel like liquid which is produced from biological material is called biodiesel. It is made up of vegetable oil, fat, and latex. It is non polluting recyclable fuel. It was discovered by Reddit Diesel and its chemical name is FAME ( Fatty Acid Methyl Ester)
Sources of biodiesel: (1) Vegetable Fatty oil: certain plants like castor and jatropha produce oil which is one of the sources of biodiesel.
(2) Petro- Plant: plants that produce latex and liquid hydrocarbon, which is used as a substitute for petrol and diesel are known as a petro plant.
Example: Euphorbia, Rubber, Oak, etc.

Note:Energy plant: these are those plants whose raw material such as starch, lignocellulose are used for the production of ethanol and are called Energy plants. Example: sugarcane, potato, maize, etc. Power alcohol is the combination of petrol and alcohol and this can be used in vehicles. Brazil is the first country to opt for this
