Requirement and importance of Renewable energy resources
There is lot of importance of renewable energy resources as mentioned following
Renewable energy resources such as Sun, Wind, Tidal,
Wave action, geothermal technology, hydro power and biomass all are available
in nature and could be converted in to useful energy without affecting our
environment.
Renewable energy resources require less time and
price as compared to conventional energy resources.
Let us discuss various aspects that shows the importance of renewable energies sources
1. Environmental benefit- as we have already discussed
that renewable source of energies are not responsible to produce the carbon
compounds during the generation of energy or power.
2. Energy secured from renewable sources is infinite as
these sources are freely available in nature and will not run out as in case of
conventional energy sources. Conventional energy sources are in finite
quantities and will require a lot of time to be form and will be run out in few
days.
3. Economical growth – as we are aware that renewable
source of energy are much cheaper as compared to conventional sources, it is
concluded that renewable source of energies will play a vital role to improve
the economic condition of any country.
4. Energy security- During 1970, oil supplies were
disturbed in India and India was dependent on supply of oil from foreign
countries instead of reducing the consumption of such energies. Renewable
sources of energies have ability to make a country self dependent in respect of
energy requirement.
It was concluded by various sector energy experts
that in current situation we are not using suitable percentage of available
renewable -energies but also we are using very negligible percentage of the
available renewable energy.
If we can use only smaller portion of available sun
energy, we will have energy more than requirement to satisfy the demand of
energy globally.
It must be note down that by using renewable source
of energy; we are not only avoiding dependency on conventional source of
energies but also we are also saving our environment for our next generation.
In current situation we normally focus on energy from Sun, Wind and water.
Development of Renewable source of energy
Renewable energy was much promoted by government of
china. When renewable energy rules and regulations were passed, at the same
time government of china has decided to fix a target for renewable energy
production and application and government of china has decided to contribute
renewable energy at least ten percentage of total consumption of energy.
Government of china has decided to achieve this target up to year 2020. In
current situation government of china is contributing renewable energy only one
percentage of total energy consumption in order to fill the demand of energy in
the country.
It was concluded that there will be huge demand of
energy, raw materials and food in china and India due to its big population of
about 2.5 billion.
These two countries, China and India, are dependent
on Coal, fossil fuels to full fill the demand of energy and these two countries
are using much coal and fossil fuels and contributing the carbon compounds in
environment and leading to Global warming.
Let us discuss the development of Renewable energy in India
There is tremendous development in the generation of
power in India. If we consider during the Independence time or approximate
sixty years ago, there were installed power unit of approximate 1300 MW
production capacity.
At the end of month of March-2007, total production
capacity of power was 1, 44,520 MW and this production capacity were achieved
through various areas such as Thermal, Nuclear and Hydro. This capacity of
producing power was achieved through various funds such as Central sector,
Private sectors and state sectors.
After generating this much production capacity, it
was observed the power shortage of eleven percentages.
According to energy experts
this shortage of power might be minimize if there is proper energy management
system and approximate forty percentages of energy could be saved.
If we consider the costing of generating power of 1
MW of new production unit, it will be approximate Rs.40 million. But if same
amount of money i.e. 40 million is invested in process of conservation method
of energy then it can increase capacity of production by 3 MW.
In order to full fill the energy demand, it was
concluded to promote the renewable energy application and this programe was
handed over to Ministry of Non-Conventional Sources of energy.
Simultaneously in order
to promote power production, Private sector- investments in renewable sources
of energy were also increased because too much dependency on the utilization of
resources of fossil-fuel such as oil & coal, in order to meet the demand of
power in country, was not suitable for the long time due to finite availability
of such resources of energy as well as the dangerous impact over the ecology
and environment
Hence, importance was
given to renewable sources of energy (RSE) not only in India but also
throughout the world…
The main sectors under renewable sources of energy (RSE) are as mentioned following
Hydro Power
Wind Power
Solar Power
Bio-mass Power
Ocean energy
Energy from waste
