The essential energy questions at the beginning of the 21st century turn around two important points: the progressive exhaustion of fossil resources and the worsening of the greenhouse effect. The combustion of fossil fuels (coal, oil and to a lesser degree natural gas) releases into the atmosphere significant quantities of carbon dioxide (CO2), one of the main gases responsible for the greenhouse effect…
Fossil fuels currently account for 80% of the electricity generated. And electricity generation is responsible for 40 per cent of those discharges into the atmosphere that are involved in changes in the greenhouse effect. Nuclear energy therefore holds a considerable environmental advantage: it permits the production of very significant quantities of energy, without atmospheric discharges and without emission of greenhouse gases. (Advantages of nuclear energy for the environment)
The oil and natural gas deposits, the traditional and most important energy sources are exhausting day by day and the search for alternate energy sources has already been started. The current oil resources may be lasted for maximum for 40 more years as per the statistics available at present. It is difficult to imagine a world without any automobiles. Automobiles are helping the movements of goods and human across the countries which are essential for the economic growth of a country.
