a)Energy implies the capacity or ability to work vigorously. It has a significant role to play in our day to day life, in fact, it is predominantly required in every field, whether it is a household, industry, communication, transport, defence or agriculture. Energy resources are broadly classified as Conventional and Non-conventional sources of energy. Conventional sources of energy are not present in the environment in abundance, however there uses are unlimited.
On the contrary, non-conventional energy sources are the sources present in the environment in large quantity but are used for limited purposes only. This article sheds light on the differences between conventional and non-conventional sources of energy.
b). Natural Gas
I. It is obtained in natural form.
II. It is available in large quantities.
III. It is used as a source of power.
IV. It is also used as raw material in petrochemical industries.
V. It is supplied for household use as LPG (Liquefied petroleum Gas) and also used for running vehicles as CNG (Compressed Natural Gas).
Biogas
I. It is obtained from shrubs, farm wastes, animal and human wastes.
II. It is available in limited quantities.
III. It is used mostly in rural areas.
IV. It is not used as raw material.
V. Decomposition of organic matter yields gas, which has higher thermal efficiency in comparison to kerosene, dung cake and charcoal. It gives no smoke. Hence, quite useful. c). Ferrous Metals mostly contain Iron. They have small amounts of other metals or elements added, to give the required properties. Ferrous Metals are magnetic and give little resistance to corrosion. Some examples of the ferrous metals we deal with:
Vehicle scrap metalDemolition Site scrap metalMetal offcuts from manufacturing industries
Non-Ferrous Metals do not contain Iron, are not magnetic and are usually more resistant to corrosion than ferrous metals.
Some examples of Non-Ferrous Metals we deal with are:
Aluminium & Aluminium Alloys ,Copper,Brass,Lead,Zinc Stainless Steel,Electrical Cable. d)Metallic Minerals:
I. Metallic mineral re those minerals which can be melted to obtain new products.
II. Iron, cooper, bauxite, tin, manganese are some examples.
III. These are generally associated with igneous rocks.
IV. They are usually hard and have shines or luster of their own.
V. They are ductile and malleable.
VI. When hit, they do not get broken.
Non-Metallic Minerals:
I. Non-metallic minerals are those which do not yield new products on melting.
II. Coal, salt, clay, marble are some examples.
III. These are generally associated with sedimentary rocks.
IV. They are not so hard and have no shine or luster of their own.
V. They are not ductile and malleable.
VI. When hit, they may got broken into pieces.

1)These fossil fuels are coal, oil (petroleum), and natural gas. Conventional sources of energy are generally non-renewable sources of energy as the accumulation or creation of conventional sources of energy takes years, once they are exploited or consumed.
2)Biogas is highly flammable and is produced through the anaerobic (without oxygen) decomposition of organic materials from plants and animals. It is similar in most respect to Natural gas (obtained from fossil fuel) used for heating and cooking at homes and industries
3)Non-Ferrous Metals do not contain Iron, are not magnetic and are usually more resistant to corrosion thanferrous metals. Some examples of Non-Ferrous Metals we deal with are: Aluminium & Aluminium Alloys. Copper.
4)Metallic minerals contain metal in raw form. 1.These metals are generally associated with igenous rocks. 2.These metals are generally associated with sedimentary rocks. 1.They are ususally hard and have shine of their own.
