The document discusses non-renewable energy sources such as nuclear energy, oil, and coal that are harmful to the environment but provide a large amount of energy. These sources produce pollution and waste, with coal and oil polluting the air significantly. While providing crucial energy, these non-renewable sources have environmental costs, so alternative renewable sources like wind, water, and solar power should be considered.

1. Extinction of the non renewable sources of energy In our days the amount of energy sources that are used is non renewable. Such sources are nuclear energy, oil and coal. Those sources are harmful for the environment but return a huge quantity of energy, in comparison to the alternative, renewable ones, which are wind, water and sun power systems. ©Koukios Giannis-Odysseas Botsis

11. Finally the price for energy is our environment.The environment we live in and grow up.So, we’d better not waste energy because we pay the price for it.
