Correct Option: D) 1, 2 and 3
The question asks us to evaluate two statements regarding non-conventional energy sources: coalbed methane and shale gas. We need to determine the correctness of each statement based on their composition and availability in India.
Therefore, Statement 1 is incorrect because it mischaracterizes the composition of shale gas.
Therefore, Statement 2 is incorrect because shale gas sources have been found in India.
D) Neither 1 nor 2
Both statements are incorrect based on the analysis above.
The question asks to identify the solar energy technology that uses mirrors to concentrate sunlight onto a receiver. We need to evaluate each option based on its working principle.
Correct Option: B) Concentrated Solar Power (CSP) systems are characterized by their use of mirrors (such as parabolic troughs, solar towers, or Fresnel reflectors) to concentrate solar radiation onto a receiver. This process generates high temperatures, which are then used to produce steam and drive a turbine for electricity generation.
The question asks for the specific term used by the Prime Minister of India to refer to countries that are part of the International Solar Alliance (ISA). This is a factual recall question related to international organizations and India's foreign policy initiatives.
