Now our First Important Question of Energy Resource Management(ERM)

Q1 Write a short note on Conventional and non-conventional sources of energy.

Answer:

• ‡       Energy is one of the most im‖portant components of economic infrastructure.
• ‡        It is the basic input required to sustain economic growth. There is direct relation between the level of economic development and per capita energy consumption.
• ‡      Simply speaking more developed a country, higher is the per capita consumption of energy and vice-versa.

Two Main Sources of Energy:

The sources of energy are of following types:

 #Based on Traditional Use:

A. Conventional Resources/Source of Energy: -          

          These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power.

These are further classified as commercial energy and non-commercial energy:

#Commercial Energy Sources:

These are coal, petroleum and electricity. These are called commercial energy because they have a price and consumer has to pay the price to purchase them.

(a) Coal and Lignite:

• ‡        Coal is the major source of energy. Coal deposits in India are 148790 million tones.
• ‡        Total lignite reserves found at Neyveli are 3300 million tones.
• ‡        In 1950-51, annual production of coal was 32 million tones.
• ‡        In 2005-06, annual production of coal was 343 million tones.

(b) Oil and Natural Gas:

• ‡        In these days oil is considered as the most important source of energy in India and the world.

• ‡        It is widely used in automobiles, trains, planes and ships etc.
• ‡        In India it is found in upper Assam, Mumbai High and in Gujarat. The resources of oil are small in India.

Natural gas has been the most important source of energy since last two decades. It can be produced in two ways:

(i) With petroleum products as associated gas.

(ii) Free gas obtained from gas fields in Assam, Gujarat and Andhra Pradesh.

(c) Electricity:

• ‡        Electricity is the common and popular source of energy.
• ‡        It is used in commercial and domestic purposes.
• ‡        It is used for lighting, cooking, air conditioning and working of electrical appliances like T.V., fridge and washing machine.

There are three main sources of power generation:

1. Thermal Power

2. Hydro-electric power

3. Nuclear Power

#Non-Commercial energy Sources:

• ‡        These sources include fuel wood, straw and dried dung. These are commonly used in rural India.
• ‡        According to an estimate, the total availability of fuel wood in India was only 50 million tons a year.
• ‡        It is less than 50% of the total requirements. In coming years, there would be shortage of fire wood.

(a)Firewood:

• ‡        Firewood is any wooden material that is gathered and used for fuel. 

• ‡        Firewood can be seasoned (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource.
• ‡        However, demand for this fuel can outpace its ability to regenerate on a local or regional level.

(b)Straw:

• ‡        Straw or hay briquettes are a biofuel substitute to coal.

(c)Dry dung:

• ‡        Dry dung fuel (or dry manure fuel) is animal feces that has been dried in order to be used as a fuel source.
• ‡        Using dry manure as a fuel source is an example of reuse of excreta.
• ‡      A disadvantage of using this kind of fuel is increased air pollution.

B. Non-Conventional Resources/Source of Energy: -          

‡        Besides conventional sources of energy there are non-conventional sources of energy. These are also called renewable sources of energy.

‡        Examples are Bio energy, solar energy, wind energy and tidal energy.

The various sources are given below:

1. Solar Energy:

• ‡        Energy produced through the sunlight is called solar energy.
• ‡        Under this programmed, solar photovoltaic cells are exposed to sunlight and in the form of electricity is produced. Photovoltaic cells are those which convert sun light energy into electricity.
• ‡        In year 1999-2000, 975 villages were illuminated through solar energy.
• ‡        Under Solar Thermal Programmed, solar energy is directly obtained. Sunlight is converted into thermal power.
• ‡        Solar energy is used for cooking, hot water and distillation of water etc.

2. Wind Energy:

• ‡        This type of energy can be produced by harnessing wind power.
• ‡        It is used for operating water pumps for irrigation purposes. Approximately 2756 wind pumps were set up for this purpose.
• ‡        In seven states, wind power operated power houses were installed and their installed capacity was 1000 MW.
• ‡        India has second position in wind power energy generation.

3. Tidal Energy:

• ‡        Energy produced by exploiting the tidal waves of the sea is called tidal energy.
• ‡        Due to the absence of cost effective technology, this source has not yet been tapped.

4. Bio Energy:

• This type of energy is obtained from organic matter.

It is of two kinds:

(i) Bio Gas:

• ‡        Bio Gas is obtained from Gobar Gas Plant by putting cow dung into the plant. Besides producing gas this plant converts gobar into manure.
• ‡        It can be used for cooking, lighting and generation of electricity. 26.5 lakh bio gas plants had been established by the year 2003-04.
• ‡        They produce more than 225 lakh tonnes of manure. About 1828 large community bio gas plants have been established in the country.

(ii) Bio Mass:

• ‡        It is also of a source of producing energy through plants and trees.
• ‡        The purpose of bio mass programmed is to encourage afforestation for energy.
• ‡        So that fuel for the generation of energy based on gas technique and fodder for the cattle could be obtained, 56 MW capacity for the generation of bio mass energy has been installed.

5. Energy from Urban Waste:

• ‡        Urban waste poses a big problem for its disposal. Now it can be used for generation of power.
• ‡        In Timarpur (Delhi) a power Ration of 3.75 capacity has been set up to generate energy from the garbage.
