5.3 SUSTAINABLE USE OF FUEL AND POWER


Exploitation means the use of something in order to get an advantages from it
Power mean rate at which electrical energy is converted to other form such as motion, heat
Energy is the ability or the capacity of doing work
Uses of energy
Ø Energy is used in running machine in industry
Ø Energy is using in cooking, warming the bodies
Classification of energy
Energy resources can be classified into two ways and that is
i. Renewable resources
ii. Non- renewable resources
Renewable resources are resources which can be replaced after being used and sustainable for example HEP, tidal energy, solar energy – Biogas
Non – renewable energy this are known as exhaustible resources, these are resources once used up they can not be replaced for example coal, petroleum, natural gas, fuel wood and nuclear energy
resources
NB.
Non – renewable energy sources
Coal is the ward old from old English term by means mineral of fossilized carbon by meaning coal is the black or brown rock which consist of carbon usually occur in rock strata in layers or veins, and this coal happen as a result of vegetative matter being deposit and compressed by being subjected to high pressure, heat and pressure turned vegetative matter into coal. Coal is the one of oldest sources of fuel used by man kind about 3000 million of years ago through history coal has been used as an energy resources, primary burned fan the production electricity and heat is also used in industry purpose example refining metals, coal formed by dead plant matter is converted into lignite than sub-bituminous coal after that subtiminous coal lastly anthracite this involved biological and geological process that took place over long periods of time about million of years
TYPES OF COAL
Ø PEAT
It is not a true coal but make a first stage of coal formation it is brownish fibrous substance, which has been formed as a result of partial decomposition of vegetative matter compressed by over-lying layers of silt

It has a lot of moisture a big content of volatile matter with carbon making only one third of it bulk and has law heating value in some part of USA use as a domestic fuel and this mainly decompose in USSR, USA and Canada
Ø LIGNITE.
Is the second stage of peat it has high content of moisture with carbon less than 4% it still retains brownish woody appearance but more compact that peat it gives only moderate of heat and break up easily when exposed to air
Ø BITUMINOUS
It hard black compact coal with a carbon content of between 40% between 15% and 40% it has a very high calorific content calorific value and its further classified into gas coal, value and its further classified into cooking coal
COAL MINING METHOD
i. Open cast mining method
It is also know as striping mining method and it is the most economical way of mining coal. It is used where se…….. are near the surface and the top layer of soil is removed and then quarried by mechanical excavator
ii. Shaft mining method
It involved the sinking of vertical shaft down the level and seams then horizontal tunnels ( galleries) are made from the shaft as the coal seams are dug out is the most common type of mining method. It is commonly used provided the seams of caol

iii. Admit or drifting method
It is used to extract coal from the horizontal or gently slopping seams that out crop along the valley or hill sides. It is commonly
used to extract coal in the valley of Appalachian mountains

ADVANTAGE OF COAL
i. It used to produce other energy sources like oil and gas example South Africa is using coal to producing oil at sasolgurg ( sasolgurg)
ii. It has promoted industrial development like of iron and steel and the manufactured of locomotives and ship
iii. It has promote the development of transport system like rail, ways and road
iv. It lead to the creation of employment opportunities
v. It has facilitating domestic activities like cooking, warning
DIS – ADVANTAGES OF CAOL
i. It is non-renewable resource’s once exhausted it can not be
replaced
ii. It lead to air population by emitting carbon-dioxide, which leads to global warming and sulphur dioxide, which lead to acid rain
iii. Destruction of land space
iv. It is heavy and bulky; thus it is difficult and costly to be transported
v. It use a lot of capital to exploitation leading to the decline of other sector
COAL IN CHINA
China rank the third in terms of both total production and reserves of coal. Coal in China was used as far back as 3000 years ago. The types of coal found in China includes bituminous, anthracite and lignite
In the country, coal found almost in every province; but actively exploited in the following principle areas
a. In shanks and shanks 1 and Shaanxi regions. The two greatest amount of coal and account for over 47% of China’s coal reserves
b. Inner Mangolia; it accounts for 25% of China’s total coal reserves. The main mining centers in this region are fen he(fenho) valley, Ningwu and along in the tatting loses plateau
