Unit 3 the problems of power generation

The shift from fossil fuels – coal, oil, and natural gas – to other energy sources, such as wind and solar power, will be one of the milestones of the 21^st century. For all practical purposes, with increasing use of automobiles worldwide, we could run out usable petroleum in this century. To avoid serious economic and social problems due to oil shortages, we need to find alternatives before we reach that point. The need is great, and the time to act is now.
