1.1 Understanding Various Terms and Conversion Factors

Readers frequently encounter two terms, viz., ‘ton’ and ‘tonne’. Globally, three
different types of ‘Ton’ (https://www.quora.com) have been recognized and these
are as follows (Box 3):
Box 3
Tonne/Ton
British Ton or
Long Ton
2240 Pounds
American Ton or
Short Ton
2000 Pounds
Metric Ton or

Let us examine the calorific value and quantum of energy (Box 4) that can be generated from some well-known commercial and non-renewable sources (Yearbook,
Energy Statistics 2013).

Since different types of fuel materials are used for generating commercial energy,
their efficiency (Planning Commission 1953) is compared in terms of calorie content.
For example, one ton of crude oil is worth 10 billion cal or 42 billion joules. Similarly,
one million ton of Indian coal is worth 4.1 billion cal. It is also possible to measure
electrical energy in terms of thermal energy. For example, one billion kilowatt-hour
equals 0.86 billion cal. Taking the thermal efficiency of a power plant and other
losses in the system, the equivalence between electricity and fossil fuels would be
one billion kilowatt-hour = 0.28 million tons of oil equivalent (in case of coal-fired
