In most MEDCs, the demand for energy continues to increase
but the source of this energy will change as fossil fuel reserves a
decline and alternative types of energy are developed.
The coal industry
The industrial revolution in Europe was based
on coal. European coalfields became the
centre of industrial and urban development.
The UK has several major coalfields.
Estimated coal reserves could have kept Britain supplied for
another 200 years. The UK coal industry has been in declaim since
the 1920s when competition resulted in the loss of the world
Coal is formed from fossilised plants and consisting of carbon
with various organic and some inorganic compounds. It is mined
from seams of coal, found sandwiched between layers of rock in
the earth and burnt to provide heat or electricity in
Coal is a Readymade fuel and it is relatively cheap to mine and to convert into
energy. Coal supplies will last longer than oil or gas. But when burnt, coal gives
off atmospheric pollutants, including greenhouse gases causing global
Oil and Gas
The UK has extensive oil fields in the North Sea and the Irish Sea. This helped the
UK reduce its oil imports. Together with natural gas, oil has replaced coal as
Britain's main energy source. Oil was cheap and was in demand from industry and
transport. Some coal continues to be mined from the remaining pits. But
onethird of the coal will be recovered from open cast sites, for example
Natural gas is a cleaner fuel than coal and it also helps the government met
international pollution agreements.
Oil is a carbonbased liquid formed from fossilised animals, Lakes of oil are
sandwiched between seams of rock in the earth therefore Pipes are sunk down to
the reservoirs to pump the oil out and it is widely used in industry and transport.
Natural Gas is basically, Methane and some other gases trapped between seams
of rock under the earth's surface therefore Pipes are sunk into the ground to
release the gas and often used in houses for heating and cooking.
Oil and Natural gas are readymade fuel and relatively cheap to extract and to
convert into energy. But when burnt, it gives off atmospheric pollutants, including
greenhouse gases and there is only a limited supply.
