Solution
There will be increasing dependence on sources of energy other than coal and petroleum in the future because these two fossil fuels are non-renewable sources of energy and they are being consumed very quickly by the increasing human population. Further, man is trying to obtain energy from non-polluting sources of energy such as wind, hydroelectric power, etc., to prevent excessive pollution that is caused by the use of coal and petroleum.
