The worldwide demand for energy is increasing day
The worldwide demand for energy is increasing day by day. The increasing use of modern means of transport-cars, buses,trains, aero planes , ships, etc., the rapid rise in the overall industrialization; the tremendous growth in population, particularly in the last 40 years, are some of the factors that have led to a tremendous spurt in mankind’s energy requirements. The biggest challenge/problem the world faces today is perhaps 'climate change' or 'global warming' which will lead to mass extinction of all life on earth. One of the major contributors to this is large use of fossil fuels (coal, petroleum) and moving to renewable energy sources is important.
