1The rationale behind using nuclear energy stems from the need to find alternative energy sources to fossil fuels (i.e. oil, gas, and coal), which are finite. 2 This is a growing concern, due to the increase in the global population, which is accompanied by an increase in energy demand. 3 The annual energy consumption rate per capita in developed countries is between 4,000 and 9,000 kg of oil, while the rate in less developed countries is around 500 kg. 4 As a result, the demand for total primary energy, which will accompany the population growth, is projected to increase from 12.1 Mtoe (million tons of oil equivalent) to 16.1 Mtoe in 2030. 5 If this increase occurs the total global stock of oil and gas would only be adequate for 250 years, thus requiring the urgent development of other energy sources, which would not deplete the stock of natural resources available for future generations.

According to the extract, what is the reason for using nuclear energy?
