Detailed Solution

1)      CNG: CNG means compressed natural gas that can be used as a substitute for petroleum, and this CNG is found beneath the surface of the earth.
2)      Plastic body: Most electronic items have a metallic body that can be heavy and costly. For its substitute, one can use plastic body coverings to make it lighter and more cost-effective. These plastics are obtained from chemicals.
3)      Plastic: Plastic can be the substitute for metal chairs, and that metal can be used elsewhere where its need is more. Plastics are generally obtained from fiber and chemicals.
4)      Hydel Power Rain: Hydel Power Rain is a substitute for using thermal power, which is generally obtained and operated from coal, as coal is a conventional source of energy, and its regeneration is impossible.
