Step-by-step explanation:
The given sentence is not punctuated correctly. In English, proper punctuation is important for clarity and to convey meaning accurately. The corrected sentence would be:
The president said that we should conserve energy.
In this corrected sentence, the first letter 't' in 'the' is capitalized, and a period is added at the end of the sentence. By punctuating the sentence correctly, we ensure that it reads as a complete thought and follows the rules of grammar and punctuation.
