• Heat Input/Electricity Output
• KCAL/KWH
• Calorific Value
• Heat Content Per Kg
• KCAL/Kg
• VARIABLE COST=HEAT RATE/CALORIFIC VALUE
=KG/KWH
– HIGHER THE CALORIFIC VALUE
– LOWER THE INPUT OF COAL

15. • It was forecasted that Coal, Natural Gas and Nuclear power will continue
to hold their importance as a primary energy sources for electricity
generation till 2015.
• Total world power generation demand(P) – 24980 TWh (2015)
• A growth from 18,920 TWh in 2006.
• Coal-fired power stations increasing their share in total generation from
40% in 2006 to 44% in 2015.
• Gas-fired generation dropping marginally from 20% to 19% in 2015, as a
result of higher prices.
• Oil use in power generation continuing to decline from 6% to 4%
• Nuclear power suffering a fall in market share from 15% to 13% in 2015.
• Conversely renewable generation (including hydro) is expected to rise
from 18% in 2006 to 20% in 2015

16. Reasons for Continuation of Coal Use Despite Existing and
Future Policies to Mitigate Greenhouse Gas Emission
Coal is plentiful, widely distributed and likely to be available
Coal has consistently outperformed oil and gas on an equivalent-
energy basis, and despite a potential cost of carbon, coal is likely to
remain the most affordable fuel for power generation in many
developing and industrialised countries for several decades.
Coal is considered relatively affordable and has less price volatility
compared to oil and gas.
The use of indigenous reserves or the ability to access a well-
provided and affordable international market can enhance a
country’s energy security and provide affordable reliable power to
drive economies and development.
The greatest increase in the demand for coal will be in the
developing countries, especially in developing Asia, where reserves
are large and low-cost. OECD coal use is likely to grow modestly.

21. International Coal Trade Growth :
21.2 quadrillion Btu in 2009 to
35.2 quadrillion Btu in 2035.
The share of total world coal consumption
accounted for by internationally traded coal
has increased from 15 percent in 2009 to a
steady rate of 17 percent as per IEO
projection.
Stability on share of coal trade primarily
reflects the ability of the world’s largest coal
consumers, China and India, to meet
substantial portions of their future coal
demand with domestic production.
