為什麼會有能源危機

會有能源危機是因為人類大量開
發能源,如石油、天然氣、煤......

The modern world depent a lot on ENERGY . The energy that we demand a lot are mainly oil , coal , natural gases ,,,,,,
These kind of fossil fuel and natural gases are non-renewable.
What is energy crisis ? Our life maybe very diffcult if all the fossil fuel is used up .And "Energy crisis" is a crisis due to the over consuming of fossil fuel in our earth crust.

因為全世界的人都在用石油和煤，石油和煤總有一天會用完，所以我們要節約用電，以免發生能源危機！

因產油國出現問題(如戰爭、政變、天災等等)，不能輸出石油，便會出現供小於求現象，就會有能源危機。
