This article lists 100 Renewable Energy MCQs for engineering students. All the Renewable Energy Questions & Answers given below includes solution and link wherever possible to the relevant topic.

Renewable sources of energy are also called exhaustible sources of energy. This energy refers to all the limitless energy sources present in nature such as the sun, water, wind, waves, earth are few examples of renewable energy sources.

Renewable energy is generated from sources that naturally replenish themselves and never run out and over 80% of total energy is consumed by humans. However the renewables are the fastest-growing source of energy in the world, example wood is a wonderful form of renewable biomass energy but if we use too much, it leads to deforestation.
