Differentiate between:

a. Renewable and son sewable source of energy.
b. Nuclear fission and Nuclear fusion.
c. Biomass and biogas.
d. Wind energy and tidal energy.
e. Solar energy and fuel energy.

a. Renewable and son sewable source of energy.

Renewable
Non-renewable
The energy sources which can be obtained continiously are called renewable sources.The energy sources which can't be obtained continuously are called non-renewable sources.
It is formed in a short period of time.It takes a long time to be formed.
They never get exhausted from nature.They get exhausted from nature.

b. Nuclear fission and nuclear fusion.

Nuclear fissionNuclear fusion
It is the process of splitting a single nucleus into many nuclei.It is the process of combining many nuclei into a nucleus.
It can be controlled.It cannot be controlled.
Atom bombs are made on this principle.Nuclear bombs are made on this principle.
Comparatively, less energy is produced.Comparatively, more energy is produced.

c. Biomass and biogas.

BiomassBiogas
Biomass is the source of biogas.Biogas is the product of biomass.
It is an energy source.It is energy.
Cattle dung, sewage, etc. are biomass.Electricity or heat are biogas results.

d. Wind energy and tidal energy.

Wind energyTidal energy
The energy generated using the currents of wind.The energy generated using the currents of tides on the sea.
The wind rotates the turbine here.The water rotates the turbine here.
It is used for pumping, sailing, etc.It is used for electricity generation.

e. Solar energy and fuel energy.

Solar energyFuel energy
The energy produced by using the heat and light energy of the sun is solar energy.The energy produced by using fuels formed from fossils is fuel energy.
It is the main source of energy.It is an alternative source of energy.
It is formed on the sun.It is formed under the earth's crust.
