Renewable energy sources are the sources of energy which can’t
get extinct over the period of time. Non-renewable sources are limited
available and will get extinct over the period of time examples are Crude oil,
Coal etc.
There are following renewable energy sources which are great
source of energy and we can tap off that energy as much as can:-
1. Solar energy
2. Wind energy
3. Hydro energy
4. Geothermal energy
5.
Biomass
energy
We will discuss about these available energy sources and all
over the world these energy sources are getting tapped abundantly so as to get
reduce the reliability on non-renewable energy sources. Also these non-renewable
energy source are not available with every country and in countries where
non-renewable energy sources are available abundantly are charging very high
for giving to other countries.
1. Solar energy:- Solar energy can be used
for generation of electricity, heating purposes and for growing plants. With over
the period of time with lot of developments
in solar cells, generation of electricity from solar energy has gained momentum
and in few years it will form major portion of production of electricity.
2. Wind energy:- As clear from its name,
wind energy can be tapped off to generate electricity. Only constraints in this
form of energy are that we can generate electricity by using wind only at high
altitudes or at planes where wind is flowing at higher speeds.
3. Hydro energy:- In this water flow is
used for generation of electricity. This can be tapped off by building dams
across the rivers.
4. Geothermal energy:- In this form
natural heat below earth surface can be used to heat homes or generate
electricity. But this type of energy is very difficult to tap off and it is
very hard to handle the heat for useful purposes.
5. Biomass energy:- By using Solid fuel
from plants and waste generated from animals. By burning both of these heat is generated
and which is used to produce electricity and even Biogas plants are used to
generate electricity and natural gas to run vehicles. Further waste generated
after generation of electricity can be used in fields in case of Biogas plants
as manure generated during that process in quite useful.
Some people
also consider Nuclear energy as renewable energy but same isn’t true as it
required radioactive material for production of electricity which is limited
available in the market. Further there are so much harmful effects of nuclear
energy. But nuclear energy is having Zero Carbon emissions. Which means that
they generate very low emissions and zero co2.
Advantage of Renewable energy sources:-
1.
Zero emissions which will leads to
purification of our environment.
2.
People can generate electricity at their
homes by using Solar and Biogas plants which ultimately reduce their
electricity bills and even now-days they can sell to power companies.
3.
Maintenance required for solar plants and
wind turbines is minimum.
4. Renewable
energy sources provide more health benefits considering zero emissions.
Disadvantages of renewable energy source:-
1. Higher
initial cost of installation
2. Large
space requirement for production of same amount of electricity as in case of
non-renewable energy plants.
3. Solar
energy dependent on weather and wind turbines dependent on wind so limited power
generation during absence of sun and wind respectively. Solar power can be
generated in day time only so energy required to be stored during day for usage
during night hours. So lot of storage space and storage equipment required for
the same.
Apart from
Biomass plants now governments are more focused towards generation of electricity
from House hold waste. House hold waste may be either vegetables waste or other
waste. Since waste handling is becoming a burden for all the governments so more
and more startups are coming up for generation of energy from this wate.
All countries
are pushing towards the renewable energy sources so as to cut their import
bills for usage of non-renewable energy sources.
