Complete the information. ice water air clouds the Earth water Complete the information. _____ _____ _____ __________ Can we mainly rely on solar and wind energy since both of them are clean energy? Why? Post-viewing One possible version: As far as I’m concerned,we can’t mainly rely on solar and wind energy even if both of them are clean energy, because the two kinds of energy mainly depend on weather condition.If the weather condition is not so perfect,this two kinds of energy may not be availiable. Write a passage to introduce solar energy, covering its strengths and weaknesses. Homework $$null
