Scientists like Albert Einstein and Antoine Henri Becquerel contributed to an interest in the study of generating electricity through nuclear energy. Their objective was to generate a cheap, safe and environmentally sustainable form of electrical energy that can meet increasing global requirements. Radioactivity was a major component of this invention. (World Nuclear Association, 2014).
The world received the consumption of radioactive energy with mixed reactions. While scientists focussed on its low cost, widespread and easy availability, conservationists, health organizations, economists and anti-lobbies begged to largely differ. The explosive and negative fallouts after Nagasaki and Hiroshima in 1945, was the first pointer to the ill-advised use of any form of nuclear energy. The Chernobyl disaster in 1986, as a result of a leaking nuclear reactor, compounded to the wide spread belief that it was like the plague revisited. Strong anti-nuclear bodies preached on its harming effects on not just mankind, but also on the ecosystem. (Misam Jaffer, (2011).
However, a contrasting thought propounded that the generation of electricity from nuclear energy reduced the dependence of energy from coal and oil. Lesser use of oil and coal meant lesser greenhouse gas emissions, such as carbon dioxide, methane, and so on. (Overview of Greenhouse Gases, 2012). The use of fossil to generate electricity was found to be more harmful, according to a NASA study. (Pushker Kharecha, James Hansen, 2013).
Any energy, be it nuclear or fossil driven, is driven with its own disadvantages. Nuclear energy, however, appears to be both ecologically and economically more friendly.
