Why was Britain geographically lucky when it came to a new source of fuel?

Britain has the largest coal reserve in Europe.

Explanation:

During the earlier era of the industrial revolution, Coal was the primary source of energy fuel that people use to power their cities, factories, vehicles, etc.

Having the largest coal reserve means that Britain could make all the production/manufactures in the country become significantly cheaper. When they sell their products to the international market, this will resulted in higher profit for Britain.  As a result, Britain become the most prosperous nation during the earlier era of Industrial Revolution.

the caste system in india is the paradigmatic ethnographic example of caste. it has origins in ancient india, and was transformed by various ruling elites in medieval, early-modern, and modern india, especially the mughal empire and the british raj.it is today the basis of educational and job reservations in india.it consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.

the caste system as it exists today is thought to be the result of developments during the collapse of the mughal era and the british colonial regime in india. the collapse of the mughal era saw the rise of powerful men who associated themselves with kings, priests and ascetics, affirming the regal and martial form of the caste ideal, and it also reshaped many apparently casteless social groups into differentiated caste communities.the british raj furthered this development, making rigid caste organisation a central mechanism of administration
