Why are we not able to find any economically feasible alternative energy source? How long can we depend on fossil fuels?
Solar power has been in use for quite long time now. But it is quite expensive. Why are we not able to make solar power economically feasible? In Indian villages, people use bio gas produced by cow dung for cooking purposes. Why can't a similar bio gas be produced from kitchen waste in urban areas? If the quantity is too small it can be produced at least in restaurants and canteens?
