In the article, "Earthships," what does passive solar mean? (I WILL MARK THE FIRST PERSON BRAINLEST IF THEY PUT THE CORRECT ANSWER :>) a clean-burning natural gas

a type of pollution resulting from cracking tires

a type of fossil fuel used for electricity

the use of the sun's energy for either heating or cooling

Passive solar means to make use of solar energy through windows, walls and the floor without using mechanical or electric devices. In an Earthship, this concept means building large sun-facing windows opposite a heavy wall, a wall with thermal mass or atleast i think it does.
