In a speech at the 90th Science Congress, internationally acknowledged scientist and former Indian president Mr
APJ Abdul Kalam mentioned a very important aspect of mankind’s future energy crisis. He pointed out that the
era of wood and bio-mass has almost come to an end. The age of oil and natural gas would soon be over within
the next few decades. Massive burning of world’s coal reserves may lead to a worldwide ecological disaster
because coal burning emits the highest amount of carbon in the atmosphere. Ukraine’s (former Soviet Union)
Chernobyl disaster in 1986 has exposed that nuclear energy can be potentially dangerous too. So according to
Kalam, the only solution that mankind can look to is the massive use of solar energy in future because it has
some advantages over other forms of renewable energies. Now why has Kalam put so much importance to the
issue of energy? The energy sources have always been a major factor of change throughout history. The world’s
petroleum consumption has increased from annually 3 billion barrels in 1930 to annually 50 billion barrels today.
In the next quarter century, the world’s population is expected to be about 8 billion which is 30 percent higher
than today. Developing countries will grow their economies about two times faster than industrialised countries.
Global economic growth is expected to continue at 3 percent per year. Consequently, the global demand for
energy will grow at about 1.7 percent per year on an average. It indicates a 50 percent rise of energy
consumption by 2030. If the world’s daily petroleum consumption is 220 million barrels now, it will rise to 335
million barrels by that time. The present reserve of hydro-carbon energy resources is limited and it will not be
sufficient to meet the future energy challenges of the world. And hence, leading industrial countries have taken
initiatives to tap alternative energy sources mainly known as green or renewable energy sources. The bottom
line of Kalam’s speech indicates that concern of mankind in the 21st the century.
