Today, there is shortage of fuels, non-renewable resources - coal, oil, gas, etc. They are being burnt simultaneously, in order, to make electricity. They are, as mentioned before, non-renewable energy. Non-renewable resources are limited resources - once they are used up, they will be finished totally. They are needed because by burning them, we can produce electricity. I believe the best solution to this problem is producing electricity by renewable sources of energy. And if it has to be implented, adults have a role rather than children.
