Today, many countries understand that not only does an excessive emphasis on developing energy sources lead to waste and misuse of resources, the countries are highly vulnerable to sudden energy crises, while the power plants destroy the ozone layer and contribute to the greenhouse effect, so that in the end it becomes necessary to spend even more money to repair the damage.
今天許多國家也都體認到，過度依賴開源，不僅造成浪費、資源誤用，在能源危機時容易受到衝擊，加上發電廠造成的臭氧層破壞、溫室效應，也只會逼迫我們必須花更多金錢來彌補。
