availability of coal

In countries, where coal is easily available as compared to the rapidly depleting petroleum and natural gas, it is possible to avert the energy crisis by preparing petroleum and natural gas artificial..

Reserves of brown coal - are mainly found in lignite basins of Tamil Nadu. They are available in small quantities in Rajastan and Gujarat. Total lignite reserves of India are estimated to be 30 billion ton..

Question: How do you classify our natural resources? Answer: We can classify our natural resources into two categories: (a) Inexhaustible resources: Renewable resources such as solar radiation, air and water. (b) Exhaustible resources: Non-renewable natural resources which are avai..

Resources which are in limited amounts and cannot be renewed are called non-renewable energy resources. Fossil fuels like coal and petroleum are some examples. Petroleum products are energy-rich components of carbon which have undergone anaerobic degradation with the help of sun's energy..

Environmental Consequences - The energy source that we actually choose depends on various factors like the cost, the ease with which it is available, the efficiency of the technology available and the environmental damage that will be caused by using that source. It is thus deba..

Summary - Today most of our energy needs are supplied by the fossil fuels. In one hundred years coal will be the only one left as petroleum products may remain only for 3 to 4 decades. Little of stored energy will be left if we continue to use energy at the same rate. Fossil fuels are non..

In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and other domestic appliances. A large share of energy is neede..

Advantages of Using Solar Energy - It is present everywhere. It is available in plenty. It does not cause any environmental pollution like the fossil fuels and nuclear power. Solar cells last a longer time and have low running costs. In the first half of the twentieth century solar energy..

Fossil fuels and hydroelectric sources are the most readily available and the most widely used sources of energy around the world. In India, most of our population is rural based and uses wood or coal, about 75% of the population uses wood as a domestic fuel. This has led to a ..

When chemical reactions take place, energy is either absorbed or evolved. A reaction is said to be exothermic, if heat is 'evolved'. The heat energy produced during the reactions is indicated by writing + q or more precisely by giving the actual numerical value on the products side. In general, exo..
