Which of the following energy sources is best for keeping the environment clean?
Wind energy and Green energy
The source paper marks option (D), Wind energy and Green energy, as the answer. Since wind energy is itself a form of green energy, this combined option is unusual, and many textbooks would instead point to solar energy or green energy broadly as the cleanest choice. This answer is transcribed as marked, with a confidence flag noting the ambiguity of the option itself.
Given below are two statements:
Statement I: Passive solar systems pump a heat absorbing medium rather than storing heat in stationary medium.
Statement II: Solar energy can produce high temperatures even in the range of 1000°C or more.
In the light of the above statements, choose the most appropriate answer from the options given below:
