**4. Conclusion**

From the present study it is observed that substantial increase in energy demand in the developing countries, due to the strong economic growth is dominating energy markets today and subsequently increasing global population deplete fossil fuel reserves is making the sustainability vulnerable. Other major findings of the study are as under:

	- The oil price is currently very high at around \$140 per barrel in nominal terms. This is much higher than after several other oil price crises, such as the Iran/Iraq war, Gulf war and 9/11 as per WTRG, 2008. According to OPEC (2007), OPEC benchmark crude price is assumed to remain in the \$50 to \$60 per barrel range in nominal terms for much of the projected period and rising further in the longer term with inflation.
	- Coal prices have had less fluctuation in comparison to oil in the last 50 years. The coal market depicts relatively constant coal prices in historical data. This trend will remain flat until the middle of the next decade, and then increase very slowly, reaching just over \$60 per tonne by 2030.
	- Gas prices have generally followed the increase in oil prices since 2003, typically with a 1 year lag. The average transmission and distribution margin for delivered gas is projected to change from \$2.38 per thousand cubic feet in 2006 to between \$2.07 and \$2.44 per thousand cubic feet in 2030.

Beyond the year 2050, climate change may be the major driver for biodiversity loss globally. The climate problem affects everyone, and everyone has a stake in deciding what should be done. It is for you to decide what actions you should take as an individual (in your home, your car, and so forth). Equally important, as a citizen you must decide which policies to support or oppose and make every one aware about disastrous consequences of the situation.
