Question
Explain briefly the idea contained in the following statement. There will be increasing dependence on sources of energy other than coal and petroleum in the future.
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.
